What makes a truly world-changing invention?. Of all the inventions of the 20th century just one could be said to have changed the world in such a way that it touches virtually everybody on the planet's lives on a daily basis. It has enabled the most rapid development in technology in history and yet you cant see the vast majority of them directly and their individual job is just to switch on and off. This is the story of the MOSFET and how it changed the world.

    One of the more important features of MOSFETs that you didn't mention is that at full saturation, internal resistance is very low, unlike bipolar transistors. This means MOSFETs are capable of switching very high current loads without generating much heat. This allows for the use of MOSFETs to replace electromechanical relays, as well as for high-speed, high-current switching. This is why our "power bricks" of today (including cell phone chargers!) have evolved from heavy devices containing iron-core step-down transformers, into tiny, switching power supplies capable of producing huge amounts of current from a tiny power supply with very little heat and very high efficiency.

    it's entirely a misconception to believe our devices work without failure, in fact our computations fail so constantly you cant run modern software without error correction, and with transistors so small tiny little particles flying through space have enough power to switch a 1 to a 0. which doesn't sound like a big deal until you realize how much a single bit of information can alter a computation. there is a bunch of basic tech support tactics drilled into the brain of everyone who works with computers, which basically boil down to "have you tried turning it off and on again?" because computers so regularly back themselves into a corner that shouldn't be there

That said, intelligent people do tend to be more interested in learning in general, and therefore are more likely get over that "I know it all!" bump in more fields than people who don't do care about looking into things in detail. That doesn't mean intelligent people do that for _every_ field (and some very smart people just completely keep themselves constrained to their specific field of occupation) but they're more likely to have a broader spectrum of knowledge and therefore more fields where they know how much they don't know.

    @@myrtistaylor5759 He does not go into great detail. That is the idea, it is an overview. He does explain that a transistor can be: *1)* An *amplifier* of a signal - making the signal stronger as it passes through. An example is that a weak radio signal can be made stronger to power a speaker. *2)* A *gate.* A gate is just that, it stops the signal, as a light switch does, or allows the signal to go through, as a light switch does. Using it as a gate it is a _relay._ One circuit switches _on_ and _off_ another. As the _gate_ is either _on_ or _off,_ it is ideal for the binary numbering system which is 0 and 1 _(base 2)._ We use in our everyday use _base 10_ because we have 10 fingers. This is a cumbersome way of using an electronic component as a device is switching _on_ and _off_ a signal, not having it continuous and moving all the way fast as in an analogue form - electricity moves at approx' 1,860 miles per second. It is inefficiently stopping and starting. But here is what makes it feasible. Having *60 billion transistors* in a device that can carry out *two billion* _on_ and _off_ switches per second, _binary_ calculations can be performed amazingly quickly. How does that make a modern digital electronic device work? A computer, _computes,_ constantly calculating. That is what it is doing underneath. The so-called computer devices we use, the function is not computing for the end user - using a web browser on a smart phone is not adding up numbers. To achieve what the end user wants, an amazing level of calculations are performed underneath using the binary, base 2 system. All performed by the Central Processor Unit (CPU) and other components that contain transistors used as *_gates._*

    A couple of key discoveries and inventions in the early days of the MOSFET were 1) the process recipe for growing gate oxide (SiO2) on silicon with low Si/SiO2 interface defect densities. 2) The self-aligned gate where the gate electrode was deposited before source/drain diffusion (or ion implant) and was used as a mask. The gate had to be able to withstand a very high temperature dopant activation anneal so had to be refractive like TiSi, not aluminum. Without those innovations, MOSFETs would just be laboratory curiosities.

    In the "naughts" I "owned" a 248 nm KrF excimer lithography laser. It was retired shortly after I was in 2009. Viewers may not know that an excimer is an "impossible" molecule formed from an inert element (argon, krypton) and a highly reactive element (e.g. fluorine) under very energetic conditions (electrical discharge). It quickly falls apart, emitting a photon of a characteristic wavelength in the ultraviolet. Even so, the natural spread of wavelengths is enough to cause chromatic aberration, so a grating is used to filter out some photons.

    A little history I learned while doing a school report: Schockly's original design worked fine - right up until the moment when AT&T attorneys did a standard patent search. Imagine their surprise when they found that his idea had been patented ten years earlier, by a college professor. They had no choice but to hand-build the early point-contact transistors to fulfil contracts.

One thing I remember hearing on a few occasions is "we have hit the limit of physics" on things like layer thickness and others but layer thickness is the one that I find the most funny because the claimed limit keeps changing . They really should just say it's the limit of current technology rather than claim it's a limit of physics , luckily not everyone believes in limits and they seek to break those supposed limits . From what I hear bacteria is being used to etch the smallest of layers which seems interesting , I would love to see that demonstrated . The next step I think will be 3D printing circuits and insulators to reduce distance traveled internally for operations and get layer thickness down even more , an entire computer could theoretically be printed into a single chip in almost any shape you wanted and would only require limited external connections .

    Bacteria are orders of magnitude larger than the smallest layers so... In regards to the limits, yeah physics does throw curveballs when you get into the single digit nanometer scale. As in quantam tunnelling of electrons and such, high energy photons from general background radiation flipping mosfets, which is why clever error correcting code is needed. And now clever architectures to further increase the performance of modern chip designs. These days the whole 5...4...3 nm nomenclature is just marketing jargon, to indicate progress in computing power, not the actual size of the circuits that are being made. As it stands, the chips are already printed in 3D, just go take a look at how RAM and SSD's work.

But then again,who really does component level repairs these days? Did they teach you how to do circuit board repairs without schematics?

    @@ebayerr Some of the equipment didn't even have Technical Orders so we had to use manufacturers manuals about 25% of the time. And those often had block diagrams and often no schematics. Yeah we had to identify circuitry at times by taking measurements. I taught PMEL for 5 years. When I started school in PMEL we didn't have calculators and worked with numbers with up to 6 or 7 decimal places. Used a lot of logarithms for calculations as slide rules were not near accurate enough.

    I've been an electronic technician for almost 40 years and witnessed most of this development. As a footnote to the comment about needing chips to create more chips: what was omitted is the time and amount of water necessary to produce a wafer like those shown. It takes at least a month to produce one wafer, and hundreds of gallons of pure water. This point is omitted when we talk about making cars, trucks, ect, all electric.

    Very good overview and review. But I think the Colossus was actually built outside of BP although it was delivered to BP because it was to be deployed there. And I think there were two distinct Colossus machines: one was pretty fixed-purpose, but the second was truly an advance and deserves its place as a first in computer history. Well done, UK! ☺️

    I play my electric guitar through a fuzz pedal with three germanium transistors. Then it goes through a MOFET overdrive pedal and then into high tech microprocessor controlled digital reverb and delay with premium FET buffers and preamp, all before it gets to my 50 watt stereo vacuum tube head. Musicians made all these technical devices into musical instruments that are still used and loved today for their sound, warts and all. Meanwhile the digital industry attempts to reproduce those old sounds, from crusty old tape echo machines to tube distortion and dynamic effects. The tube industry nearly died if not for the venerable tube amp and pedal Guru Mike Mathews of EHX. The guitar pedal industries managed to get obsolete analog Bucket Brigade chips made again, just so they could make the classic Analog Delay pedals again. The history of these devises is fascinating to me being a techie and a musician. Bravo for good story telling. I'll subscribe.

    My 91 yo Dad was on the R&D team at Texas Instruments and developed the integrated circuit. It had something to do with masking to control oxidation and phosphorous and silicon. This discovery made multiple circuits possible on one slide. A new manager came in and the RnD went on vacation. Jack Kilby took credit although he had virtually nothing to do with it. He was awarded a Nobel Prize for the most critical invention in history. Just talking to him. He told me he was successful and the engineer believed he messed up. Dad told the engineer Dub Little “Now we can install 25 circuits on one chip!!! I need to video interview him soon!!! He’s 91 !!!!

    That is a fascinating history of the development and use of solid-state devices. I remember how thrilled I was in the early 60s to have my pocket 9V AM radio with its 8 or 9 transistors and a jack for an earphone, so I could listen to Top 40 AM rock radio around the time of the British invasion(1964 - 1967). Later I marveled at the use of MOSFET front-end voltmeters that had the high input impedance necessary for making voltage measurements in RF circuits, where no loading of the circuit was necessary. Previously, we had to use vacuum tube voltmeters(VTVMs) for that purpose and they were often barely stable enough to get good measurements.

    Dennard's scaling hadn't ended back then, so you'd see chips double in clockspeed in just a couple years. going from 8mhz to 15mhz to 33mhz to 66mhz. Nowdays chips have hit that tdp limit and IBM, AMD, and Intel haven't been able to break past ~5ghz (IBM still makes chips though they are for the mainframe market)
