Ultra-fast Quad 3-input NOR gate from GigaBit Logic

[@jdrevenge]

Gallium Arsenide*, Also, Triquint merged with RFMD in 2015 to become Qorvo. :)

[@pacadet]

Was just about to post that haha

[@EvilmonkeyzDesignz]

I appreciate the corrections, thanks! The arsenic slip was my fault, and I didn't scroll down far enough on the Triquint Wikipedia page to see they merged with RFMD to make Qorvo 😅

[@KlodFather]

@@EvilmonkeyzDesignz - GaAs is the semiconductor of choice at VERY HIGH frequencies and in aerospace chips handling UHF and MicroWave RF signals... They were serious about speeding up this unit with the built in decoupling and GaAs as the substrate. Good one. See if you can get your hands on some high power GaAsFETs from MicroWave and Radar equipment... I am certain that they are very interestig. The Russians are very good at making them. Their main factory is in Belarus and should make an interesting video if you can get your hands on some.

[@dsracoon]

Also Triquint is named after the III-V semiconductors they use (being GaAs one of them)

[@KlodFather]

@@EvilmonkeyzDesignz - You do good work. A correction or two sometimes is no problem... Its how we all grow and learn. What you are doing here is so very cool and interesting, we are all learning with you. This channel is quite a ride. I wonder how many FSU (former soviet union) semiconductors have doodles or sprites in them and how bizarre or macabre they are.

Massive respect to the engineers and engineering that went behind this chips I mean holy crap

[@heinzhaupthaar5590]

Take a deeper look at things like VUV lithography machines, processes and what huge amount of accumulated knowledge and research went into something we usually view as rather banal, if you like such "wtf, holy crap" - things. The whole story of the continuing race for ever smaller IC structures, the development of transistor gate technologies like FinFET and Gate-all-around etc. is extremely fascinating and absolutely awe-inspiring. And it revealed something more or less - depending on your angle - profound to me: For most of our whole existence, humankind always has been in a state that could be built back up in a relatively short amount of time if civilisation were to collapse completely, proven by the fact of several civilizations all around the world reaching similar stages of advancement independently over and over again - But now, now we're at a point we might very well never reach again if there ever was a complete collapse. It's simply way too advanced, high-tech stacked upon high-tech stacked upon high-tech - just to build "simple" components necessary to manufacture such "highest-tech". If things aren't going the right way and circumstances aren't quite favorable there might not be a way to ever reproduce our current advanced technologies - and there might never be enough incentive again anyway. After all it's not exactly essential or even remotely necessary to have low nanometer range advanced architecture ICs and such. We could do just fine without, and that applies to quite a few of the higher-end technologies imo. Anyway, just an interesting thought I wanted to share 😅

[@Shurtugal_107]

Idk what these are, but cool!!

[@CarlsTechShed]

290 picoseconds! For some context, light travelling in a vacuum would travel just 86 millimetres or about half the height of an iPhone screen during that time!

[@944LS]

Only 86mm, psssshhhhhh

[@zakkomatic]

Every video you post intrigues me. Keep up the great work!

[@deang5622]

Gallium Arsenide is the correct name. I used to design chips in GaAs like this, but with 30,000 gates.

[@philip.t]

Can someone please exlain how do they manage to cut these chips? They are thinner than any kerf I could imagine.

[@jameskinard]

They stick them to a sheet of tape and then slice using a diamond saw, the tape holds it in place to then later be picked out and wirebonded.

[@philip.t]

@@jameskinard thanks james!! I do that too when wood working. maybe I should start my own FAB xD

[@ahmetmutlu348]

Depends o which part you talk about but main rule using photo image of circuit and print it on copper or whatewer ut is then fire the laser laser concentrates on black parts tough burns them faster so you can burn specifix schapes.... second is similar but chemical version where they paint copper or whatewer is used circuit on ... then dip it into chemical which melts copper , so painted part of copper stays intact which is the part you see.... sadly we dont have microrobots for doing this using another technique but who knows may be military has it 😅😊

[@RayceVR]

I was working with logic gate’s yesterday. The standard ones we were using were 10ns per inverter!

[@briancase6180]

It's actually gallium asenide. And, CMOS pretty quickly became faster than GAs circuits. GAs circuits have advantages today, but not for dense, high-speed circuits.

[@YodaWhat]

Gallium Arsenide is abbreviated GaAs.

[@herrbonk3635]

Although comparing CMOS to GaAs is like comparing railways to steel.

[@8BitNaptime]

arsenide, not arsenic

[@EvilmonkeyzDesignz]

Yup you're right, that's my slip 😅

[@petergibson2318]

The molecule is composed of One Gallium atom bonded to One Arsenic atom so his minor mistake was that he got the semantics of chemistry wrong.

[@ericsuperstar746]

You need to make more shorts please please please please please it’s therapeutic to watch it didn’t take me long to watch your full inventory

[@herrbonk3635]

I personally can't really stand his way of talking though.

[@MillhouseDaPlug]

Man i live your videos, i like building pc's but im addicted to watching videos like these, so happy i find this page all the cgi videos are not the same lol

[@Jackpot1711]

can you please show how a latest iPhone chip looks like under microscope.. thank you

[@annnonimous9929]

No way screwtube allows that. Apple would be on him before he finished uploading.

[@darkarvindrakkar9898]

I think when your panning around you can see the decoupling capacitors, they are the interlocked (but not touching) finger traces

[@YodaWhat]

290 picoseconds... That was quite fast for those days. It's equivalent to 3.45 gigahertz. 😮🎉

[@abusaleh2222]

Respect for Engineers, machines, softwares..etc behind this work :)

[@newsolution5669]

Hi. Don't you have any diagrams of processors from the Motorola 68060 family? I'm looking for diagrams, documentation, and everything that could be useful?! you don't know where to find it?! Regards . !!

[@Intercomp_salam]

In 1985, how they wrote the small writing on the chip??

[@AppliedCryogenics]

I wonder how the speed of this compares to an equivalent gate in a modern CPU or GPU.

[@mOwOhib]

Where has bro gone?

[@EvilmonkeyzDesignz]

Two back to back trips put me out of commission for a bit. Flying back from OpenSauce today. More chip videos are on their way! 😁

[@WolfmanDude]

Is it ECL? ECL is the coolest type of logic ever!

[@bakagaijin7452]

What exactly makes ECL cool? That is basically your grandma's op amps. Unlike (Bi)CMOS unsuitable for ULSI things with its power and heat. Yet modern CMOS beats it in speed. CML is a different beast of the mixed signal world though related.

[@WolfmanDude]

@@bakagaijin7452 I really like they way it works, those differential circuits are very intuitive to me. Also you can just make your own high speed logic gates from normal transistors. A few years back I made a ECL XOR gate from rf npn transistors that worked up to 500MHz. They still make high frequency counters and prescalers with ECL logic to this day, there is no CMOS replacement that I could find. Maybe I am biased since ECL logic is mostly used in expensive/special devices while I associate CMOS with cheap and crappy consumer electronics :D Maybe its kind of "outdated", but did that ever prevent something from beeing cool?

[@absurdengineering]

@@bakagaijin745210k family ECL works without a ground plane on wire-wrapped boards. Building something like CRAY 1 with non-differential CMOS signaling would not have worked even today. ECL’s claims to fame are differential outputs “for free”, and the relatively constant power consumption. Keeping VCC or VEE from jumping all over the place in ECL was relatively easy compared to the ultra-spikey CMOS. Sure, ECL does not scale to high density due to crazy heat output. But as far as it can be scaled, powering it is easy and basic 70s power tech does it just fine. For comparison just look at what it takes to power a modern desktop CPU. The requirements for transient response of the supplies are crazy, as the entire CPU can ramp from a fraction of an amp to a couple hundred in a couple microseconds at most. ECL did none of it. ECL is also the lowest transistor count means of building fast discrete digital logic from BJTs. Not of any practical use, but for homebrew logic it’s a good thing.

[@absurdengineering]

@@WolfmanDudeYup. I second your fast transistor experience. It works pretty damn well even with through hole parts with a bit of ingenuity in PCB layout. It also doesn’t disturb the supply lines much. With fully differential outputs with differential termination it is approximately a constant load on the supply whether it switches or not.

[@WolfmanDude]

@@absurdengineering You are right, the constant supply current is another great property of ECL logic that I forgot to mention!

[@LP-fy8wr]

If there is not some type of coffee table book with all of these Doodles in it you need to make one brother. I would buy that today

[@bijingqueen]

ok but there are no resister or transistors here only the lines how does that work:(

Man there's all kinds of gold for recovery

[@jacoblf]

the electroplated gold is only a few atoms thick. 100k ICs might approach 1gram.

[@matterickson5651]

Those older chips are not electroplated it's the newer ones that are. I used to work for an electronic recycling company and we would extract the gold from those exact chips and the recovery rate was pretty high

[@jacoblf]

@@matterickson5651 how many chips per gram of gold?
