- I have finally been successful in creating a conductive, clear layer of indium-tin oxide on a microscope slide. In this video, I show the process and explain how sputtering works.
Came here from linuses ridiculous build lol
What?
I was literally just here for the same thing.
Same
My grandfather, Manfred Kaminsky, was one of the discoverers of the sputtering effect on metals in the early 1960s! He worked at Argonne National Laboratories! I believe he was also on the team that discovered radiation blistering on solid surfaces
Hey, the setup you have there is quite impressive, especially since it appears you made most of it yourself. I do have two pieces of advice:
1) The crack in your ITO disc likely isn't due to the lack of cooling. Don't get me wrong - you will need cooling. However, cracking is often the result of thermal shock, not overheating. I suspect that you just turned your power supply on to whatever current / power you wanted. The sudden localized heating caused by this is what makes ceramic materials crack. You should ramp your supply - start at a low power, then work up to what you want. I recommend a rate of 1 W/s or less. Also keep in mind that no matter what, your disc can only take a limited amount of total power without bad things happening.
2) You might want to integrate a shutter, so you can shield your substrate from deposition until conditions (presssure, power etc.) are just the way you want them.
Hope this helps, and the best of luck!
Both very good tips. shoot for ~3W/cm² max w/ ITO.
You can probably get an inexpensive MFC on ebay and control the pressure much better, you could even make a control loop if your pressure sensor has any kind of electrical output.

Anyone here from the Linus Tech Tips video?
Yeah ^^
Which video?
@@gcr100 th-cam.com/video/l_IHSRPVqwQ/w-d-xo.html saved with timestamp on when he talks about the panel
@@nathanielcutajar You are my friggin savior. Thanks, man!
Which video is that, can I get s link?
Beautiful machining, I say this as a machinist. I really like this channel a lot and the things you do, absolutely fascinating and a wonderful blend of technologies and fields. awesome stuff man. awesome.
Ben, I think your selfless TH-cam howtos should make you a candidate for something like a MacArthur Foundation Fellowship. Unfortunately, the Foundation does not accept nominations. I just hope hope someday, somehow, the collective body of what you explore and share here on the Internet will come to the attention of the movers and shakers in the Foundation, e.g. Robert Galluci, Joi Ito, Daniel Huttenlocher, Mario J. Molina, as you are doing a lot of good here. The MacArhur Foundation is probably besieged by academia with their sophisticated fund raising divisions that the garage tinkerer who gladly shares his discoveries has no hope for consideration.
Tinkerers are an overlooked bunch and the United States needs to foster more of them. (I was acquainted with Stan Avery, he started his label empire in his garage, and if he were alive today, I'd bring to his attention what you do, I think he would have admired what you accomplish.) With more money available to you, I think you, with maybe an assistant, could do even more.
that shiny reflector in a Maglite flashlite is coated in aluminium by the evap method ... I used to do that for work !
Great video, clear explanation. What makes the sputtered aluminum firmly stick to the glass? Why doesn't it just wipe off easily afterward?
@Alphonso Stufflebean nope, no one gives a single damn.
@Alphonso Stufflebean also a friend requires the person to find you as a friend back

speed
Probably van der waals forces because good contact is achieved, similar to cold welding or why gage blocks wring together.
Ben I would love to hear your thoughts on how to find read and gleam data from academic literature and patents. It is a soft skill that is hard to communicate but you are clearly extremely good at it and I think it would be an excellent video topic.
Very nice and informative presentation Ben. Kudos.
One thing worth mentioning though, is the lack of bonding.
You will find that bonding the target to the backplate using Indium will greatly reduce failure by thermal shock, which is an inherent problem when working with any oxides/ceramics targets.
Water also helps you to not exceed the Curie temperature of your permanent magnet.
Dude, they're are way below that! They're talkin nanometers!
I look at your shop and think this guy is goofing around and having fun. Then I see what you make, and I think holy crap he's a mad scientist making lab grade equipment.
And he does it all just because he can
"All the Stupid Safety Interlocks that Make it Difficult" -Famous Last words of Many People [10:56]
I think it's about time you start building a cold fusion reactor. The stuff so far has been childs play ;)
Oh and you should really consider joining Reddit, very intelligent group of people there that can help you with any doubts you may have throughout your experimenting. Good subreddtis to start are www.reddit.com/r/askscience and www.reddit.com/r/science
that sputter gun you machined is absolutely incredible.
Thank you Linus for recommending this video
You're Ionizing things in a vacuum chamber and You're going to take apart a Microwave to get a diode out of it ? Do You think that You could do some Chemical Vapor Deposition to make a Diamond ? You're just a step away from using a microwave to ionize methane (CH4) and I think they also said Hydrogen in a slight vacuum , above a diamond seed , and grow a diamond off of that seed ?
Ben, I need video of the sputtering gun in the dark!
Wow that revives some old memories of when I worked in a university physics lab in about '75. The postgrad at the next bench to me was trying to do evaporative deposition. He was struggling because his heater kept burning out. He kept coming to me as the resident electronics guru for ways to improve the power control. He ended up borrowing a wardrobe sized stabilized DC power supply from the lab next door, but still was eating heater elements for breakfast. Getting tired of being dazzled by the light from his rig every time he ran it, I suggested putting some tinfoil around it as a heat reflector. He didn't believe it would help and asked our boss. That worthy started scribbling on the back of an envelope, muttering "reflectivity of foil, fourth root of energy ratio, absolute temperature..." "Yes it should be able to get you to 1700°C." Thus encouraged he tried it and it worked.
You can avoid cracking the target by gradually increase the power applied on it (5 W per minute). You can find a document on Lesker website about power density on various metals and semiconductors.
"And the hose runs to my argon cylinder"
Of course it does. Where else would it go. I too need to go and check on my argon cylinder that I happen to have in my garage.
This guy is awesome. Is he a uni professor or something? I can't think how else you would just GET all this stuff.
He's actually Mark Watney
A lot of these things are available from suppliers online. It's not cheap, but if you have the time and money... A quick google and I've found an argon bottle available for delivery from £100. Other parts he's machined himself so all you need is access to milling machines, lathes and pillar drills as well as the raw materials. The only other thing needed is the expertise, which is what Universities and youtube videos are for.
he worked for Google doing research and then worked for valve doing hardware prototyping so he makes the big $$$
You buy it. It's not anything controlled or secret or special. Most people don't have a need for it, but it's a common welding supply, so it's not exactly hard to find.
antiswattt3 I would estimate it to be somewhere in the range of Stahlrim and Argonian.
Ok guys please dont keep saying “who else is here bc of linus tech tips” we dont care
linus send me.
I would leave a chemistry joke, but all of the good ones argon
Reported.
Neon sounds like "not him" or "not this one" in Russian. But no one grins at Uranus instead.
Really cool stuff, Ben! I really enjoy your videos. I think indeedItdoes is on the right track with better thermal conductivity to prevent cracking. In the cleanroom I work in, we always use a thin copper mesh between the heat sink and target to improve thermal conductance. Also, when sputtering ceramics and ITO, I have found that a ~2 minute ramp up and slow ramp down is critical to prevent cracking your target.
I've seen people on youtube splattering with home made Magnetron. Is that a similar process? Or are they different horses for different courses? Thanks for the upload and awesome description of your splatter chamber :)
You mean with a high voltage transformer that come from a microwave? I don't really see what you would need the actual magnetron for.
@@allornonebaby I mean with a home made magnatron. No parts from a microwave. See Aplied Science chanel diy magnatron.
The magnatron creates magnetic field which orientates the plasma field to the desired polarity and also does some stuff I don't quite follow with the free electrons.
man, you are 100% pure awesome
The magnetic field direction combined with the 'direction' of the current flow should make an observable difference. Also.... placing another magnet of the correct polarity above the target may also improve the process according to my understanding. If you are not familiar with Ken Wheeler's study of magnetic phenomena it might be worth looking into. It may not be particularly useful for this project. But I am all kinds of excited to see that plasma field you created there and it has inspired me to start yet another ridiculous project, lol Great work, btw!
Спасибо, очень понравилось, в поддержку!
Any chance you could build a device to produce carbon nanotubes? I'd love to see that.
ElGatoLoco698 me too, I wish I could make an electron microscope so I could check what kind im making quickly
He has done it already
I watched all your "vacuum" videos - nice job! Since I am also in the progress to build a similar system to sputter Al to make mirrors: I can see your vacuum measuring sensor is facing straight into the vacuum chamber. Isn't there the danger that over the time, you will also coat the inside of your penning/pirani gauge?
Currently, I have to decide if I place the penning and/or the pirani gauge straight onto the chamber's bottom plate OR to put them both on the tube which connects the oil-diffusion pump with the chamber's bottom plate.
What would be your recommendation?
Thanks again for your great videos.
I'm a huge fan of your omnipotent work skills and your projects.
Could you do something like a titanium nitride coating with this sputtering machine?
Would it work if you took a bare piece of titanium as sputtering material and fill your chamber with nitride instead or argon?
Pleas try this if you like to and make a video of it, I would highly appreciate that.
Cheers Max
Or maybe anyone else could answer to this?
ANYONE?
I feel like a ghost posting comments here...
Max Lindner Yes, titanium nitride can be sputtered. Yes, it can be done by starting with titanium and adding nitrogen to the chamber. I showed the reactive sputtering process in my self-cleaning glass video. I'm not sure I will do a TiN coating, but it sounds interesting.
Applied Science
Nice, thank you very much for the answer!
Fantastic job on the machining, its like a work of art. I can't wait to see what you plan to do with CLEAR conductors
whats the cheapest vacuum pump i can get away with? would an ac/refrigeration pump be ok? i tried with a frige compressor and got plasma but it kept arcing so i guess there was too much air inside.
edit: now have a decent leybold pump. please tell your chamber material and thickness, and working pressure
In theory yes, but is really useful to get better vacuums
I'd recommend using compression fittings for the cooling system. Threaded connectors have a built-in pathway for liquid to exit, even with sealants. Liquid exiting and causing shorts on this wonderful POC would be no bueno.
hey just a quick tip, if you dont already have a variac buy a router speed controller , to power your microwave transformer, they only cost 20$ at harbor frieght, basicly they are 15 amp triacs with a potentiometer
Replace nylon screws? Your two basic choices are ceramic and fiberglass. What did you end up going with?
How on earth are those the two only options and considered basic?
Teflon or PEEK would be way more realistic hahaha
You make it all look very easy! I`m very impressed with your ingenuity.
It’s black widow but on a smaller scale!
so ur the one who took the ark reacter from tony stark huh???
Fascinating video as usual ben! I've no idea how any of it works but its still very interesting.
Ok, looks like we have a real Tony Stark here...
My thoughts exactly.
This is beyond awesome!
Keep up the excellent work, man. You're an inspiration to us all.
hey, i would love to see u build a pulsejet engine. :) just a request. love the videos. thanks for all the entertainment!
(or rather, i would REALLY love to see u find a good use for one!) lol. :D
Pulsejet powered ultralight aircraft
SQUAZZ that would be so fucking loud.
Great work, thanks for sharing and keep them coming! :) P.S. Would love to see something about vanadium dioxide as a photochromic agent for IR reflectivity. Seems to be some buzz about it for years, but no revelation. Could it be... "vapor"-ware?
Wonder if multi layer microprocessor could be made with sputtering tech?
+minuteman2012 Most micro chips are multi layered, they have to be because some components that are less or more conductive than others have to go over and under other parts to make the element work, like with a transistor for instance.
+minuteman2012 YES you can, thats how they are made professionally
sure. then you only have to master semi-conductor CAD design and micro-lithography.
This guy is different. He is doing things on youtube most people aren't.
Where did you get the ITO disc?
You're a man with infinite resources! Great job, Ben.
Doug
Please make completely transparent circuit boards, could look amazing with just random soldered components on a glass slide.
Regarding photoresist, I can see that you are using shortwave lamps (~250 nm)? I found it works much better with 365 or 400 nm lamps (a.k.a. disko lamps) with normal Positive photoresist. The reason why it works better is sandwitch of glass, ordinarry window glass, which does not permit 250 nm to penetrate. 365 nm on the other hand has much better chance to do its job.
Impressive work as always. Some questions:
1. Why is the spark plug necessary?
2. Have you measured the uniformity of the coating thickness? I imagine there is a tradeoff between uniformity and efficiency?
3. Those ITO targets must have been expensive. Do you think you can still get good results with the cracked one, or is copper contamination an issue?
4. What is the flux density of the magnetic field? Does the flux density affect the rate of ionization?
5. How easy is cleaning over-sputter from the chamber?
Do you know your answers? Can you explain them to me?
There was an old Scientific American "Amateur Scientist" article that featured plans for a really simple sputtering device. I tried it with some success.
flic.kr/s/aHsjwkrVoe
Like one of the other commenters, I too wanted to make CO2 laser mirrors - an output coupler using a salt window, to be specific. To my dismay, the salt crystal cracked from the heat!
how is there no arcing between the 1000v and ground when they're so close together? lower current? or just that it's in a vacuum?
Current doesnt really have any effect on arcing. Static electricity makes lighting bolts you can see with your eyes, but it has almost no current. Arcing is a function of frequency, pressure, and voltage. The lower the pressure, the harder it is to get an arc. Now, thats not to say that you wont have currents going from the inner layer to the outer, its just that it wont be visible.
Static discharges can have a really high current (up to a few amps 😳), but their total energy is really small because they only last a *very* short time.
Also good for small spacecraft.
ltt
This equipment is not likely to work well, although should work with metal targets. For ITO, plasma needs to be generated by a RF magnetron. Direct the plasma at an ITO target. The target needs to be bonded to a copper/steel plate to conduct heat.
Thought I'd look up lens coating. Wound up here. Maybe Fuji has a video, not sure. It's not going to detailed in any way if there is one.Good to know Argon gas will have a future. You didn't explain wha the coating on the slide will be for, though.
Wow Ben. That is some laboratory quality machining there! Nicely done.
Nice work, you're obviously not 100% satisfied with it yet, my advice is worth the paper it's written on, but an objective suggestion can be priceless, and you're already doing your due diligence in the K.I.S.S. methodology.
Stick with I until you're 100%!
Hi Ben; I know you did this video several years ago. However I was wondering if you'd be willing to relook at this process using laser pumped ablation in thin capillary tubes with a torridial magnet on the outside.
I've had some incipient success with this in down an dirty proof of concept runs on Argon plasma chambers.
Given the spot size of 405 nm blueray lasers and the reduced cost of specialty matieals such as LiF windows; which should be able to be formed into capillary tubing like quartz tubes; it seems like a simple 90° spinning polarizing mirror could be usedbin conjunction with a speed controller to puls a high frequency focused laser into a 1/16th I.D. LiF Capilary tube that holds pencil lead like 1 mm diamter rod targets.
Essentially your capillary tube with target wire feed can get subjected to vaccum with Ar, laser evaporated, flow foucesed inside the center of the capilary through small exterior torridial coils wrapped around your capillary tubes holding each targer fillament then have the other 1/4th -1/2 of your 405 nm (or UV possibly) direct the path of the ions at the top of the tube into your depostion chamber, and then back onto your target.
Given the inexpensive cost of some of the laser diodes now that have spot sizes which get down to sub 400 nm size on the case of the Blue ray disc lasers; it seems to me one could very inexpensively source multiple lasers diodes that are inserted on the interior of a vacuum chamber system with a ~500 μm lens cover with a 2 way mirror coating; that lets them use pulsed timing synced with time of flight to push or steer ions through a mirror coated capilary tube system such as a hollow core fiber optic cable and final accelerate them onto the surface of the material one wishes to deposit onto.
Uniformity could be an issue that has a high time cost to get down; but the trade off is one could essentially extend the same priciple they use in the Anycubic M3 Premium DLP mirror actuated resin 3D printers; and extend that to multi fillament array feeds to sputter based 3D printing like deposition.
Someone may already have suggested UHMWPE to replace the nylon, but I've been too lazy to check all the comments :-)
Why is nylon not suitable for a vacuum chamber?
If I don't know that, why suggest UHMWPE? Because it strikes me as being nylon on steroids (I'm an enthusiastic noob, not an expert).
Thanks for your awesome videos Ben. I do some vacuum experimenting myself and worry about x-rays. What are your thoughts, do you think you are getting x-rays in your sputtering experiments?
Nah, he said in the video that the voltage he is working at is only 1kv. To make x-rays, you need a much higher voltage (like, 30 times higher). I'd be more concerned about UV radiation, but I guess the glass chamber also filters a lot of UV.
I have a Harvest Right Freeze dryer and am trying to hunt down a leak. The freeze dryer is practically brand new and I was able to get down to 500mTorr in about 10 to 15 minutes (at 7,000 feet elevation). But now I cannot get past 700 mTorr even after 30 minutes.
It might be the pump or it could be the door seal or ??
How do you troubleshoot vacuum leaks?
Don't know if you're still monitoring comments on this video, but I just thought I might offer a couple of suggestions to maybe help, perhaps people like myself with only a little bit of college education. I was just thinking that it might have been better to FIRST explain 1) what is sputtering, 2) what is it's purpose, 3) why would anyone want or need to do this, etc., instead of breaking everything down and THEN explaining those things. I think, for me at least, I would have had a better understanding if you had gone that route. Just a friendly suggestion. Keep up the good work!
You can purchase a package of 25 75mm × 25mm × 1.1mm indium-tin oxide coated glass slides for less than $750.00 Why bother making your own given most of us don't have machining tools costing many thousands of dollars.
tnx for vid !🔬🆒📚 , I see your resistance went from approx +300Ω to around 500 some ohm when you increased the distance between ohmmeter test points at begining of vid.🆒 If i could do that i would try making some transistor ( mos & bipolr) layers , and maybe amplifiers & logic gates . learned a lot here tnx !📊📈
I have taken apart some large sputtering machines in the past. They used an MKS 250 pressure controller with a control valve and vacuum gauge. Probably $300 total on ebay if you know what your looking for. I can calibrate and tune it for argon free if you like, I work with vacuum equipment for a living so this be intriguing...
Why not use FTO instead of ITO? Its physical properties are much better overall and less expensive than the ITO... im not quite sure on the transferring process other than the FTO requiring a constant 600°C over the 300°C of the ITO sputter process.. but seems to me would be much more of a usable result as well as possibly an overall easier process in the transfer based on the temp and the FTO being directly adhered to the glass rather than the film segregation with ITO glass... good topic though and great execution.. must have looked over the necessity of the whole constant 300°c deal and the temper/expansion and contraction of glass.. but nobodies perfect and cannot possibly account for everything in the experimental stages, thus the need for the word experiment.. even if you bleeped out your reaction, it still would have been a fun thing to look back on.. how you always voice your mistakes, if you had a gag reel of everything would fir sure get more kids into physics/science/etc.. in my opinion.. keeping it up though still years later!! Thank you.. :)
Is the sputtering material anode or cathode? The cooling hoses would make a lot more machining if it could spin. The advantage being additional power by pneumatic power. It sounds silly, but you can be more efficient by having hybrid power.
Hey, Would a speaker like mechanical vacuum chamber work for this application, in sputter machine design? Could injected sound frequencies, could play a role in atmospheric pressure differences, of argon atmospheres. automation is a must. Anybody?
Thinking along the lines of additive printing do you think this could be converted into an alternative 3d printing technique???
Imagine the resolutions it'd be capable of let alone the types of materials you could print with or combinations you could combine...
Cool vid reminds me when I had the opportunity to operate ODME cd producer spudder gun and high grade pucks for cd coat on lexan disc. In fully automated robotic machine. Was amazing tech 20 plus years ago
it is required. thermal expansion of copper is 1.6 mm per meter, per 10 degrees. ceramics are around 0.4 Depending on the elasticity of your disk, your gonna shatter it with only a 30-degree temp differential. I don't sputter, but I make precision bedplates, mixing glass and metal plates and not having them shatter or distort each other. You could try tungsten instead of copper, its thermal expansion is very low. the lowest of all the metals. and it conducts heat well enough, more than steel, less than copper and alu.
Additionally, your working in a vacuum, there is no conduction of heat from your copper mass, and plasma it hot. Therefore, so is your block. Watercool the poor thing.
I know a house with a tunnel that goes under the basketball court for a 19th century boiler. If I use pulleys to make mechanical advantage, a tethered balloon can fly upto 700'. The balloon could land on top of the gym.
Maybe it could be used for some kind of machinery calibration. Either for low cost, or for places where it's hard to visually inspect. e.g. Apply conductive paint where you don't want to pay for adding another sensor. Measure it at the factory for calibration data. Later the paint wears off and no one really minds, and it was low cost.
we evacuated the chamber, then back filled with .99999 argon back in the gold old days...I don't recall pressure control being all that difficult...but that was automated...and a long time ago... we had a gate valve that would close off the cryo pump to the chamber during sputtering...every so often the system would need to be shut down, and the cryo condenser would be brought back up to room temp to "defrost" ...I don't recall water cooling at all, but it must have been there ...
try using a voltage across from gun to your microscope slide like it is done for spray painting I do think this will make the process more efficient and better coating of your microscope slide. Just build a plate behind your microscope slide an charge it with the opposite voltage from the sputtering plate voltage. Should be much more attractive as you ramp up the voltage across these two plates and reduce power needed. Just like a high voltage on a TV tube attracts electrons to the face plate and makes the picture. Best of luck .. let me know if it works PS: ( Do you give rewards?) ha ha ha .. How thin do you want ? I can help more if you like my idea.
Aluminized mylar is made with deposition. So, searching with a hall sensor for nanostructures makes sense right?
And I though I was impressive by building my own lead screw with all the design analysis. You know electrical and machining.
What are you trying to do by depositing ITO on glass? I work in the optical industry and one of the coatings that we deposit is ITO. We use electron beam deposition and it works just fine. Sure we use expensive vacuum chambers to do this because it is a complete process in order to achieve an Anti-Reflective coating but in the simple form that you are trying to achieve I would use the electron beam type of deposition and the crystals at 6 mHz are really inexpensive.
I learned the evaporation method way back coating my first telescope lense with aluminum was quite exciting to see a sheet of aluminum just vanish and coat the glass.
It would also be good for aviation but I don't know if a rotating cathode magnetron would be possible, but I think, "Where does the force go?"
Ben, did you contemplate using aluminum for the anode body before ultimately making it from copper?
Applied Science, I have one question. How much did the ITO disk cost? I'm assuming it's very expensive.
If you make a pv cell that is 12% efficient at converting solar radiation into electricity and you are able to measure that it has a 16% partial reflection and the thickness is 1um, the partial reflection at 0.5um is 0% partial reflection and the thermal efficiency can improve.
I have succefully sputtered copper in glass, however, when I try to plate copper (galvanic acid copper bath) to thicknen the layer, the deposit come off the glass. What possible is hapening? thanks for any help and great video.
Question. If you ionize argon by applying 1000 volts, why do you need electrons to hit Ar+ toward the target?
"Bloody Hell, Ben" moments: 4
You make me wish I had your motivation.
Small commercial sample prep sputter-coaters don’t get much lower vac than 300mTorr. But also, they are careful to set the stage at the sweet spot. Horrible to admit this, but in a pinch I’ve used a dc welder as a supply.
It makes me wonder if something like this could be used as an ion pump for getting down into ultra high vacuum territory. It seems like very similar technology just with a different magnet configuration.
Negative 1000volts?. No such thing. You would be sucking electrons out of the ground.
Can anybody help me out? I'm planning to do my own vacuum window. How long until chamber evacuated till the desired pressure in this setup?
Maybe it's not silly. Scale experiments should probably be even more efficient.
The central rod that connects the sparkplug to the source material, how do you keep it from wasting power by forming a plasma between it and the grounded tube that surrounds it? Also, could this rod have expanded from the plasma heating and caused the broken disk?
at UMIST Manchester as a student in 1990 we were demonstrated a sputter coater, it was a molybdenum boat with the silver pellet and it just blew it out . big time . 50A ,
So, after it goes in through the magnetron, I thought I would use it for propellant in a microwave plasma torch. The kind with the wave guide inside the tube reactor.
The only paper I read about a rotating cathode magnetron was a sputtering paper. I theorized it as a way to apply kinetic force to magnetron after I saw a video about the rotating anode x-ray tube. Then, I can regenerate thermal during an endothermic reaction. Etc
Etc.
If I had a microgrid, or weatherband with conditions for sun or wind at green energy installation sites, I would include that into the automation. Like if a sun is over my solar panel or over the solar or the wind field has no wind it would turn off. DigitalFM.
hello! is there a way to send you a private mesage? im attemping to designing a sputtering chamber to coat borosilicate tubes and I have a few questions I simply can't find an answer to on google. If you have a few minutes to spare to answer I'd appreciate it!
Cheers!
