What's inside a microchip ?

In this video I take you on a tour of the visible internal workings of a 27C512 EPROM microchip, with the aid of an optical microscope at up to 800x magnification.
With any luck, you won't find it too boring and you'll learn a bit about what's inside a microchip and how they work.

[@toshineon]

Really gives you an idea of how complex computers are. It's insane how precise the manufacturing have to be to make all of this work.

[@jyrgenruut]

This is an extremely old IC... you could even make out the block which saves the bit (not too sure about EEPROMs but I don't think what he said was 1 transistor really was 1 transistor... the transistor part of it was probably even smaller). Nowadays one transistor is just about over 500 times smaller than that one block. You will not be able to see it under an optical microscope... even electron microscopes have a hard time picking them up right now.

[@TheHolyReality]

***** then how the fuck are they made? who sees whats going on and is it going on as it is planned?

[@jyrgenruut]

TheHolyReality It is all regulated by computers nowadays. They make a batch and then check a few chips for their functionality - if they all work, probably the rest work as well. To see how IC-s are made you can search youtube - there are a lot of videos on it.

[@alexmcmahon2810]

+Jürgen Ruut No no no, they can see and manipulate INDIVIDUAL ATOMS (and have been able to since 1981), transistors are clearly visible to Scanning Tunneling Microscopes. There's a video, by IBM, called a"A boy And His Atom", made out of atoms. You can google pictures taken of microprocessors by Scanning Tunneling Microscopes and a whole pile of things will show up. One can look at fairly current cross sectional images of apple's mobile chips, and clearly see transistors. STMs are commonly used for validation of chips, too. "A Boy And His Atom": /watch?v=oSCX78-8-q0

[@jyrgenruut]

Alex McMahon I didn't say it wasn't possible. I just said that it is hard to pick them up. Seeing down to atomic level is not really a very easy job, it takes quite long to get the clear picture.

[@CMMikeAdamsPFForensics]

Guys... in 1973 I went to work for Ross Perot @ Texas Instruments in North Dallas. My first job was in the electronic calculator manufacturing line and more specificlly I ran a machine which formed and cut each of the three leads attached to the transistors that were inserted into each calculator's printed circuit board (mother board). Unlike the microscopic transistors in this video our transistors were about the size of the tip of your little finger. The chip you see in this video would hold hold maybe two of the transistors we used then as opposed to the millions or billions that would fit today. That is called progress.

[@BrassLock]

C.M. Mike Adams At around that time in Australia, guys were selling calculators to Life Assurance Salesmen and other businessmen as a full time job, and making a very good living at that. Some could afford to drive a Volvo, which was a sign of commercial success. Recently I bought a similarly featured calculator for 20 Thai Baht (approx 80 cents), which also demonstrates "progress".

Thank you for this video. It took me back to when I was a Technician at IBM Research. I did the design verification on the CAD systems and then once the wafers were made, I would saw the chips, mount it on a chip carrier and painstakingly wire bond it. I think we used silver wire because it was easier to ultra sonic bond to the aluminum pads. It was also more flexible to loop up so it can cross over another wire like a bridge without shorting.

[@RubenLightfoot]

Loved this! Great to see it all under a microscope like this! You mentioned not being sure how the addressing system works... based on my limited understanding here's some more on that: The address pins are used to specify which MOSFETs (the type of transistor which makes up the memory) to connect to the IO pins by applying voltage to them, turning them 'on' or 'off', in order to define a binary address. That address is then connected to the IO pins of the chip via a series of logic gates between the pins and the MOSFETs making up the memory. This EPROM has 16 address pins, so an address would look something like this: 1001000000010000. Each of the possible 64,000 address combinations then corresponds to an 8 bit memory location made up of 8 tiny MOSFETs which can be 'on' or 'off'. So, in this case, we might find that address 1001000000010000 contains data 00101100.

[@TheAwesomeManDan]

They are Floating gate MSOFETs (FGMOS). The gate is isolated from the circuit and acts as a floating node, so it can hold a charge (the data) for a long period of time.

this is an EPROM from an early GM OBD1. or at least the same part, if that's not what it was pulled from. The remarkable part is that this chip is roughly 40 years old. Modern day computer processors are one of mankinds most incredible feats. So incredible infact when you watch production videos, they have trouble explaining it

[@JoeyaoChou]

Usually we use Alloyed aluminum or pure gold as bonding wire material, not Silver. Because according to my knowledge, Silver can NOT establish firm connection. Nowadays copper is also used because it's cheap than gold and lower resistance than aluminum. But using copper require special manufacturing process.

[@hardscorerockkssss]

firm connection was not issue,but to small amount silver you could add into connectin..simply it means you need more silver than chooper to make good connection..that was real reason why solver was not used

[@ChrisFEJackson]

I agree 90% of what you say and you say quite aptly with a semantic appraisal lending toward reminiscence. Ok gold is a better conductor than silver, the wires here I can't tell if silver, many materials were used in these devices depending upon application and complexity. The bonding process is a "stamped" type under an ultrasonic 'scrub' to bond onto the aluminium pad and package. I designed a stress pull system to determine the strength of bonds of devices many years ago. For aerospace industry, where the centrifugal forces of such devices underwent in certain times of travel ;). It's nice to hear an open & honest description for once with the added interest and amount of knowledge respectfully given and understood. Good fellow :) btw the "M752" number is the manufacturer's mask number used in the Lithography process(s).

The machine was turned off and a sign on the power lever stating DO NOT TOUCH was place also at the breaker panel as we always did for safety. A employee who did not read English or French or Spanish nor the Icon with a lighting bolt hitting a person as a universal language turn the thing on in both places. The machine drove that same Eprom deep into my fingers in same angle you had yours sitting. in two areas the legs went clear through. The Doc in the ER asked if he could have it after he removed it to add to collection in one room of stuff removed from all kinds of items from all parts of body areas. I went back there to take my kid for a posible brock arm and that chip and other items were still there.

The technique for bonding the wires on the die is called cold welding. It works by pressing two clean metall pieces together with high pressure until they meld and form a bond.

The reason why they are able to use less pins per transistors, is simply because they have multiplexer circuits inside them to address which transistor (or memory address) the data goes to

[@julianhafner3380]

You wondered about how the wires are connected. The process is called Wirebonding, this particular one is done by so called wedge-bonding, the connection is made using temperature, force and ultrasonic power. Check out some videos it’s awesome. I also do that in the lab.

Looks like the second bond on what's called wire bond Ball Bonding . It sticks by using heat 100C and friction weld from ultrasonic. The first bond is the ball and the second one cuts. A small flame or spark (EFO) creates the next ball.

[@beanerama9]

I've always wondered how precisely has to be the printer (?) that designs and prints every single transistor. Ok, I might be incorrect; but how do they even get to make those microscopic plaques to be so perfect?

[@TheAwesomeManDan]

They use a process called photolithography-much like making a PCB. There are numerous steps but the main 'printing' is done by a laser, either photons or electrons depending on the precision needed. The entire process is repeated for every layer.

[@lilikoimahalo]

I just found out that during the photolithography process the light patterns that pass through the mask are reduced by a factor of four by a focusing lens and then projected onto the wafer. Now the whole process seems much easier to accomplish to me:) however, I am still in awe on how to read and store, and how everything is interconnected to allow the software to work hmmm

[@Bruno-hd9qo]

The way you narrate really made me remember when I was reading Brave New World...

[@Finkelfunk]

Well, you are making it sound like the transistors hold the memory and the data of the chip. This, however, is only partially correct. It's not just any transistor, it's a MOSFET. The MOSFET works a bit like a transistor, only that it depletes a bit differently. Getting a voltage towards the gate of those micro MOSFETS will cause a shift in the p-type layer of the MOSFET, causing electrons to be able to tunnel through from source to drain. Aka: A bit was written. If you apply a negative voltage to the gate, the p-type layer between the n-types will stop passing charges, thus resulting in a blockage between the n-type layers. This is a free bit.

[@c14ips17]

I think he termed a genera term that is transistor. We know transistors can be divided into BJT an MOSFET. The same MOSFET can be classified accordingly. so yes it is MOSFET which can offer the ability of memory.. does any one knows that water we seen around has memory capacity? Because I know.

[@Finkelfunk]

C 14 IPS But a BJT and a MOSFET are two entirely different mechanisms, although both are classed as "transistors". Kind of how an electric eel and a carp are in the same subcohort, but both are two entirely different fish.

[@c14ips17]

+Finkel - Funk yes...otherwise both field effect transistors and bipolar junction transistors would have made no distinction. It could have been used interchangeably. right?

[@adriandinanski7656]

MOSFETs and BJTs have distinct differences, yes, but it's still perfectly acceptable to refer to both simply as 'transistors'. It's in the name after all, they are transistors, but with some differences between them. And strictly speaking it isn't just a MOSFET in an EPROM but a FGMOS. Again distinctly different, but still a transistor.

[@Finkelfunk]

Adrian Dinanski Well, fair enough. Still I'd consider a BJT to be something entirely different through the way it works. The differences between those and actual memory cells in CPUs for the Cache should also be made, but then again, this goes into microelectronics engineering and that's about where my knowledge starts to get very thin.

[@musictrans]

hi all. i am going to write easy version for you to understand. codes present the language. language as every other. how to store the information? simple black and white. white is one bit info for example. or light is on. to understand what transistor do, u must understand the electricity. battery for example is just 2 metal plates with different electric polarization. what happens inside electrical circuit? electrons wants to jump or flow from one plate to another. humans come to idea to make electron pipes. so electron flows normally inside the pipes, but some transistors are set like switch. that is the catch! with turning on and of light u can write the code. how to memories the switch position? to understand this process u need to understand the chemistry. basically it is all about electron barriers. inside there are pools full of the electrons and the idea is to make them flow from one pool to another. in memory effect for example electron pool is empty and electrons can not jump to second pool. I hope it helps. by dt

[@leonc.k.7346]

E Nonyabis the chip probably uses circuits called demultiplexers or “demuxers” to select a row and colom to output a signal. Demultiplexers have n number inputs and 2^n outputs, if a binary number is entered like 1010 (10) then it will turn on input 10. And why circuit boards aren't atomic sized? Because that would be impractical, most circuit boards are used to connect components, if they were small it would just make it difficult to connect components. Probably

working as a cleaner in "bnr" bell northern research i had the pleasure of not having to vacuum a very large space for almost a month while day and night a team of designers poured over a color plotted microchip image looking for a design flaw during pre production .. kinda funny seeing a bunch of guys on there hands and knees following traces and circuits .. it was blown up to about 80x 80 feet and far enough back in history to be a single layer only .. still quite a marvel when you consider that 80 x 80 image compressed to less than 1/4 inch square and they were still using magnification at 80 x 80..

Mike Cartman good stuff! Bad for the designers for sure, not amusing.

Mike Cartman Eventually they found a small black screw from your vacuum cleaner had lodged in between the digits 1 and 7 😞

Nice !!!! Thank you very much its my FIRST time fully understanding what IC's really are

[@sparticus214]

Those primitive chips were used in vcrs to generate a signals. for example converting composite to RF.

I grabbed a loaf of bread and rub it against my speaker. I can taste a butter.

[@rammaychannel]

Yup. I ever worked in microchip factory in 1996. Wafer, dye, compound, gold wire, ect.

A transistor doesn't store a bit :D It can only TRANSmit a bit of information, or not, based on an input signal. Only an "SR Latch" or "Flip-Flop" stores bits. They're often made out of 2 NOR gates at 4 transistors each. So 512.000 bits x 8 transistors, which is technically --quote-- "at least 512.000 [...] transistors" I guess.

[@shubhammaurya3671]

These transistor are small as 10-100 nanometer

I am watching the same video 2 years later. Wow
