I wanted to clarify one part of this. I recently worked at that research fab in arizona for intel as a contingent worker, and have held in my hands those glass substrates, very cool stuff. But i wanted to clarify, their organic substrate wafers are also rectangular. They only use circular wafers for logic. I would hope thats common knowledge at this point (thats not a jab at you, thats a fingers crossed for any nda i might be under)
you do very cool stuff man! I as a pilot I appreciate people like you a lot; without you RnD lads planes would be less tech more Manual! Namaste from Bharat 🇮🇳🙏🏼
Why is logic still on circular wafers? I thought I had something to do with the way they make the silicone Crystal ignots as a cylinder and then cut them. I think they probably do some kind of spinning operation which favors circular dimensions. So why can't logic go to however they're doing the square wafer substrates if efficiently? TIA.
@@ariisaac5111 Even if using round wafers is entirely last-gen, there is well established supply chains, lots of infrastructure that is paid for and profitable. There is a huge market for legacy chips, they go in lots of cheap IoT devices and are probably the bread and butter of most of these companies profit wise.

Those mysterious eyes transcend her excitement through the camera, lips curling into a subtle, elegant smile directed at you.

My goodness your smartness combined with your beauty is so mesmerizing, I am willing to believe you everything..."
Glass could be bonded to something more rigid like diamond. There was one physicist in Germany who figured out how to grow flawless diamond crystals in a microwave oven. He needed them for his Q bit experiments. He actually grew some for a necklace for his fiance. The diamond cutters scoffed at him because raw they looked black. However when cut and polished they were stunned. Glass is a supercooled liquid with a very low elastic limit. However there are some types of glass that are much stronger to resist shattering.
I still remember in the olden times, they grew SiO2 (glass) to insulate the layers. During that time they spoke of better substrates, like Silicon on Sapphire which was resistant to radiation, but those were expensive. Now, we have gone so far that we have diamond as a heat sink for thermal management, just mind blowing. Great video, once again.
I wonder if the semi industry will follow the same path telescope making did going from glass to pyrex to cervit to zerodur and even more exotic variants to get improved thermal and dielectric properties both in manufacturing and use.
Not necessarily. The optimum glass for a substrate would have the same thermal expansion as the chiplets so zerodur might cause a problem by expanding less than silicon.
I have been saying optical computing, including use of glass, will be the future for quite some time. In fact, I think some form of amorphous programmable glass will be best. You can basically "tune" a neural network on the glass substrate, then lock in the metamaterial surface patterns, then use light input as the signal and the output is the computed result. If you need to change the function of the chip, change the internal amorphous glass structure and you instantly have a new network that can process on different tasks.
Thank you for this insightful video. The shift to glass substrates is largely driven by the need for much tighter design rules, enabling denser redistribution layers and reducing parasitic effects-key factors in achieving better 3D IC integration at high frequencies
Great! I just love glass, it is literally magical. The ancients were spiritually awed at how something made from sand could end up in glorious works of cathedral art.... P.S. As an hobby, I used to do stained glass windows for my home... Spiritual, yeah, for me and mine❤
Should add that when we refer to glass there is a lot of chemistry and physical nature involved when it comes to its properties...I know this having studied a lot of glass engineering in pursuit of some projects a few decades ago and of course the material science of it has really expanded in understanding. Looking forward to more...and more. Cheers.
Many MOSFET devices have internally connected Zener diodes on the gates to reduce the chance of static damage to the gate. the most useful characteristic of a Zener diode is a constant voltage drop under conditions of varying current. The field-effect transistor (FET) is a type of transistor that uses an electric field to control the flow of current in a semiconductor. It comes in two types: junction FET (JFET) and metal-oxide-semiconductor FET (MOSFET). FETs have three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source. FETs are also known as unipolar transistors since they involve single-carrier-type operation. That is, FETs use either electrons (n-channel) or holes (p-channel) as charge carriers in their operation, but not both. Many different types of field effect transistors exist. Field effect transistors generally display very high input impedance at low frequencies. The most widely used field-effect transistor is the MOSFET (metal-oxide-semiconductor field-effect transistor). Using glass as an insulator is good until it gets a crack in it because a static charge will find the path of least resistance through the cracks rendering 99.9% of the rest of the Non cracked glass insulator useless. This is not a new technology Anastasi, this is widely available information in the world of us FCC Amateur Extra licensed radio operators and commercial radio and radar endorsed operators as well. I like your enthusiasm on the tech subjects though.
Hi Anastasi you know as an electronic engineer I thought about it , using the glass as a substrate when we start using fiber optic instead of cooper wire, and now it's a reality, Wow!
Anastasi, I love your videos. Please make video on how to make a simple chip at home that contains just one transistor, two resistors, one diode, one or two capacitors. Start from design to finish. I will be glad to learn something new.
I have been a material RD researcher for many years in the field of Ceramics/glass. And a dedicated stained glass restorer / builder . Glass is at the Beginning of its come back .
I work at Intel in a fab and I was working on their glass substrate wafers. It's really cool to hear you talking about something that I've been working with. It happened that way with catalyst heaters for the polishing as well
Interesting video, thanks for sharing. We have been using silicon substrate in chips for so long, it's almost surprising to learn that it is finally about to be replaced.
Wow, thank you for the info' . The way to deal with shock stability is to laminate! look at bullet proof glass and shrink the dimensions. Float glass is a super cooled fluid which has a grain in line with its production process. Take two sheets of glass, transpose one at 45 degrees and put a thin film of polymer between the two, you now have a shock resistant glass. The coefficient of expansion is the same if the buffer polymer between the sheets is the same. Thanks again for you podcast
When we "discovered" America, it was full of bison, deer, elk and fish filled the lakes and rivers, that needed no veterinary care,, and which provided ample food. Then we decided that we had to "fix" it, by cutting down the forests, and plowing the land to feed livestock. What were we thinking?
Love how informative your videos are can you start to cover general technology news as well,I really like the direct research based way you present the changes in the chip industry I don’t know it’s just an idea I guess
In 1965 when Dr Moore published Moore's Law, no one dreamed we'd get as far as we have come. The amazing part is that we haven't hit all the limits to improvements yet.
There has been a lot of discussions about photonic transistors in years past, almost entirely using light. So this glass wafer tech is a stepping stone towards that goal
As a photon moves through space, normally space is the ground; black points transitioning with plank astral surface area points, two grounds exchanging imaginary transform axis. But the photon is many times slower, so in a snapshot of time, the two grounds latch onto it and barrel shift in the 4096 dimensions range, thus it doesn't have an absolute chiral radix, but churns the space with most of its energy. The implied vector means unradixed points are infront and post radixed points are behind. A very juvenile iacobian cramer rule can be observed in its power over frequency spectrum.
@11:22 I can see *Corning* getting into the substrate business and partnering with the planned *TSMC* chip factory which is being built in the *US.* Now that would be one heck of a *Chip **_Fab._*
As the CEO of Intel put it - they as well as the whole industry will be exploring periodic table and use all kinds of materials to deliver innovation in the semiconductor space. Experimenting in labs is going on with TFETs, GFETs and others we don't even know about. Human ingenuity is endless as long as it is stimulated and supported👍Thank u for this vid!
Years ago hard disk manufacturers switched from aluminum to glass for the platters. The surface was smoother and without the micro-pits in aluminum. As far as shattering, Sediver in their glass insulators and Corning in Gorilla glass make "toughened" glass that does not shatter easily.
Can't believe I didn't think of this.. After all, glass has been used for hard drive discs for years for the same reasons - it's thermal and physical stability over time.
In the late 1980's we used ceramic casing as THE solution bringing the desired thermal and mechanical properties. We ruled out glass for fear of the migration of light ions, which could contaminate the silicon. By that time, a wafer was some 4" (10cm) in diameter and a "normal" size for a microprocessor was about 1 square centimeter ! ;-D
I made a small PCB our of glass for my Masters Thesis in 2005: it was gold deposited on chromium to make a rectangular rat-race balun. Worked to get my Masters 😀. Then I did my PhD 😀
Love this in-depth analysis and update on this amazing new development in silicon chip /processing fab technology. One question though, for at least 10 or 20 years I recall silicon on insulator being commonplace at high end for high-speed communications and maybe even photonics applications. How is this very different than that SOI technology and white only now has it come to APUs/CPUs? I'm guessing so I was only good for small-scale things like LEDs or I've been with transistors maybe, and not systems on a chip integration on the insulating substrate.
Similar but not the same. Silicon is an element, and is used for making semiconductor chips. Sand is an oxide of silicon, similar to the way rust is an oxide of iron. Glass is usually a combination of several metal oxides. The advantage of glass is that its thermal expansion can be designed to be the same as silicon. The disadvantage is that glass is by definition amorphous; that is, not a crystal. Silicon used for semiconductors is made from crystals. This can be a disadvantage because crystals do not expand thermally the same in all directions, whereas glass (in theory) does. So perfect thermal expansion matching is not really possible.
Glass has a tendency to flow even under gravity, at a room temperature. Clearly visible when you look at the old windows. I understand that is a different type of glass, but still it would be interesting to see, how this problem is going to be solved.
@@c94d44027 That is false. The old windows were created as disks spun around and were thicker at the ends. When they were cut the original window framers always put the thick end down. Look it up.
@@c94d44027 not quite true, here's a quote because I'm too lazy to type it all out: "It's not totally bullshit, per se. Glass is an amorphous solid. The viscosity of glass is really high, but the bonds between the molecules are not as strong as the covalent bonds in crystalline solids (like diamond and quartz). But the "proof" in old window panes is total bullshit. The bottoms don't gradually get thicker than the top because the glass "flows" downward due to gravity, but instead, the panes were made in a non-uniform thickness back in those days, and the thicker part was oriented downwards for stability. Also, just because it's an amorphous solid doesn't mean it flows. I mean, glass has a greater viscosity than even some metals like lead. In summation, this is a classic case of science textbooks not knowing what they're teaching." Veritasium has a pretty good video on this if you're curious
When I saw the rectangular sheets, I imagined a visual of new machines that print the chips the same way a laser printer does but on the scale of newspaper printers. That would be a boon if they could pull it off. It would definitely drive chip prices down.
Great video as always. However it would have been very informative if you explained why only now is glass technology possible. Also a nod to the semiconductor electronics of actually forming transistors on a glass substrate would be appreciated. Thanks.
