I recently showed my son your videos, and he wants me to get a microscope so we can open this old Intel CPU that I have from 1992! He sat and watched your shorts with me, for at least half an hour 😎
I'm glad to hear he enjoyed them! I definitely would have loved to have seen this sort of stuff growing up. If you haven't already picked up a microscope, I'd recommend checking out the "Digital Microscope Comparison" video that I posted a few months ago. It would help set your expectations if you end up getting a digital microscope with the intent of looking at silicon chips like this. A digital microscope is definitely the lowest cost to entry, but unfortunately you won't be able to see as much detail as I show in these videos. I'm sure you'll still have fun looking at that CPU though!
It's a AMD AM29050 CPU from 1989 to 1991 it was run. It took a huge amount of effort to google it.. none of the wafer numbers led to anything but a CPU search for a particular year with the R60A,65A,70A,75A leads to the AM290x0 series like the AM 29020,29030,29040,29050 range of CPUs
Very likely a 386SX 40mhz clone of Intel CPU all the way to the 486DX2 60mhz but because it's a 1990 wafer it's a 386SX clone.. i've tried to post a copy and paste of the actual specs and TH-cam keeps removing it..
Did work for a few years for Philips (in my country the Netherlands in the factory called the MOS3) and did make silicon wafers in the 90's and most of them where 1 chip TV's chips. Did see many... really many wafers under a microscope and they look amazing!
Backgrind is also responsible for removing excess, unneeded silicon. Essentially, a wafer processing in-line has a lot of backside silicon that more or less acts as a "thick" carrier. After backgrind, all you're really leaving behind is some backside silicon, protecting your epixial/epi growth silicon (grown low-defect silicon that gives fundamental life to transistors) and everything built upon it the epi Si layer.
Could there be an element of recycling in this? Like, could they process and re-use what they took from the back? I reckon they'd save a whole load of cash if this was possible.
@@Ryan-lk4pu Never heard of such a thing personally. Backgrind usually ends with a rinse and dry cycle to clean the wafer's backside. Plus, silicon dust is a particle issue that needs to be contained - either be it from a dropped wafer lot, a wafer stress break inside of a processing tool, and even backgrinding. Silicon recycling only typically happens when wafers are scrapped from events such as double processing, no effective process rework flow, wrong recipes, wafer lot drops, etc.
@@jurassicpark104Given the shortage of sand becoming a bigger problem, I’d be surprised if they don’t start using a reclamation process at some point. Maybe supplies aren’t quite low enough yet to justify that though.
@@rfichokeofdestiny The nice thing is that wafers that are misprocessed can be melted down! The amount of wasted silicon from backgrind is minuscule compared to the amount of saved silicon from scrapped wafers put towards recycling efforts.
There is no shortage of silicone for wafers. It's like the 3rd most abundant element on earth. Can scoop up beach sand if needed. Purifying it isn't that difficult too.
I think the architecture of chips when looked up close is a bloody art form. Thousands of tiny lines in specific patterns to create an output from an input
@@user-co6ww2cm9k I'm simply comparing the probable use case for the marks he was unable to identify. I'm familiar with the process of making dies and know they aren't colors.
Those crosses could be registration marks. In semiconductor fabrication we use those to align different layers/colors to ensure the layers are correctly laid down. Yeah, it's the same same only different. Fiducial markings to align layers, same in photolithography as it is in printing, same as it is in making/assembling PCBs. Fun fact, with the ever-smaller feature sizes of chips requiring tighter and tighter alignment, the days of microscope and eyeball based optical alignment of fiducial markings has gone the way of the dodo bird. Machines doing alignment, using higher frequency light to resolve finer dimensions.
I think they’re actually CD bars. Registration marks are usually box-in-box. The lines running up and over other geometry is probably to check for out of process window focus errors caused by patterning over topography from previous layers.
You know all Nvidia cards have the same chips right? They get given the boards and gpu chips straight from Nvidia, the only thing board partners design now are the coolers.
@@Mo-gk9qb what he meant is the chip quality. best chip you can get is the most center ones and going outward, quality got worse. the worst quality would be located to the most outer side of uncut wafer. so let's say 4090, the golden bin would be the center die while let's say the 4th prints from the center still could pass as 4090 at bare minimum spec
@Mo-gk9qb calm down and learn how to take a joke. And incase you're one of those who swears binning chips doesn't happen, I have news for you. It happens.
My uncle used to work for NASA in a project and he ended up getting his hands on two TSC695F chips and bunch of other chips. He gave one to me few years ago and I've been dying to look inside one.
The way you were talking about it's fragility, and you handling it so, gave me strong Chris Parillo show vibes when that guys broke that Edison phongraph crlinder.
A few months ago I was given a 1978 ceramic intel eeprom that had a small window on top of it because they were reset using UV light. Making a video on one of them might be interesting if you can find one
Well if its reset with uv... well maybe a modern uv laser with a tiny beam size about the lithography size could selectively reset different parts? Idk the function of why the uv reset but... maybe it makes it do a new thing. or maybe a uv projector type laser that can change the shapes it projects to make different shapes and patterns on the chip surface in live operation? I do not know enough about it and maybe my idea is trash lol... But I'm always looking for atypical uses for everything that may make function do otherwise than deaigned. Shrugs.
Back in the early '80s I was blown away staring down a microscope at a 68000 cpu our university had gotten from Motorola. It has only gotten more amazing.
How does one actually get into the field of developing these chips? What kind of classes would you have to take to learn about all of this? How many people work on a chip like this, and how the hell are they designing it? Do they like define what they want from the chip, and use some algorithm to calculate the architecture of the chip? I have so many questions lol
So the squares on that disc are the chips? And that’s straight from the AMD factory? So they still need to be cut out of the disc? How would they cut them if this is the case? Absolutely loving these videos
Can i send you some small samples of electocoat primer. Ive been told it looks like velcro or pumace. Therefore if its OEM parts i can seal dorectly and paint with out sanding and keep the corrosion protection more intact
I was in a facility that produced these chips in the late 90’s. Amazing!! The process and integrated chops were invented in the USA, but now these miracle devices are proton China and other Asian countries SAD!!
@donniev8181 it literally is an answer thou 🤣🤣🤣🤣😅 If you want a more detailed answer that you probably won't understand, it's outdated compared to modern processors because it's built using a less advanced process node so it has less transistors in one integrated circuit compared to what can be created using more modern & advanced techniques.
@cryptocsguy9282 No, you gave your opinion. Your opinion is irrelevant. Not only did you just give an opinion, but you gave an opinion without citing any examples to back it up. I asked how these compared to modern-day chips, and your answer addressed nothing.
I might have to unsubscribe; the more I watch, the more I realise , I know nothing.😕 (p.s. I'm 60 years old, ( thus the use of 'p.s ).' but still feel about 25 ). 😀
It must be amazing to live through all the technological advancements from the 60s onwards! Especially the 60s and 70s must have been amazing in terms of people their technological optimism. After all; those were the times when science fiction involved nuclear powered everything, flying cars and interplanetary travel! To this day I therefore marvel at technological foresightedness of people like Arthur C. Clarke and numerous other industry leaders of the 60s and 70s onwards. I am currently 38 years old and consider myself lucky to have experienced the slow trend of digit(al)ization and miniaturization of many existing technologies. Especially when you know what came before a certain technology; you become increasingly appreciative of it!
I'm younger, but got a job repairing the old stuff. Pretty incredible to see the changes. Stuff they didn't teach me in school because it's obsolete, and yet here it sits on my work bench waiting to be repaired and sent back to the field.

You should send it to this dude
It would be really cool if we got to see you open up a chip from a smaller process node like 180 or 45nm. I love ur content!
The small feature sizes you mention are had to make anything out with even a 500x microscope
@cristalscrystals7148 those process nodes are smaller than the one used for the chips in this video from 1990

WOW... excellent channel
It would be interesting to know what you paid vs price if it wasnt scrapped. The latter number would most likely have to be retail of finished chips.
I have a request! Can you do an AMD Athlon 64 processor? Keep up the good work and my best to you and yours good sir!

Where do you buy the silicon chips or ICs? On eBay or where?
Any chance at getting one of these working? or is that process too complex or the wafer too damaged?

Promis chip.
The double cross is a symbol of rulership
I was in a facility that produced these chips in the late 90’s. Amazing!! The process and integrated chops were invented in the USA, but now these miracle devices are proton China and other Asian countries SAD!!
Could it be one of those wafers that get processed into AMD CPUs, except this didnt end up as a finished CPU?
Could it be a micromosaic chip? Those were fabbed by AMD as well at a certain point!
It’s that quantum array
"Diced." The plural of die, is dice..... O_0 This is the first time I've heard that term used in this context and my mind is completely blown!
What devices were these AMD chips used in ?
Where do you store all your parts? :D
I'm looking to buy a silicon wafer got any extras?
You should make prints.
How do i buy one ?
Ebay! I think the seller still has some left. It should be this one:
