When I studied, around 1992, the professor said, that replacing analog, chemical photography with digital cameras was impossible. It would require at least 8 Megapixel! Unimaginable at the time... In this industry, you are out of date every 6 months, so it appears. Others back then were positive, that the first 33MHz PCs (was it 286?) would never work, because it is just too high a frequency... And today, they still have some wiggle room left to improve electronic circuitry and the production process. But also that will end, rather sooner than later. I wonder what will then come next... Me personally, I have no idea. Nonlinear optics? Biotech? Maybe asianometry could enlighten us, how the non-electronical future might look like.

@neo3418 The first 33 MHz processor was i486. There was a 33 MHz i386, too (AMD took it further with 386DX40 MHz). Intel's fastest 286 was 12.5 MHz. After launching i386, Intel moved all its atention to it, and Intel didn't allowed that second source partners could make the chip. So the second source partners, stuck with the 16-bit 80286, had no other option than develop the chip clock. The fastest 286 achieve 25 MHz - made by Harris. Most 286 motherboards topped at 20MHz, due to the scarcity of higher speed chipsets. There's an additional problem about that, because AT(ISA) bus runs at 10 MHz max, so the chipset has to decouple the bus from the processor.

Most EEs at 22 already have their EE Batchelor degree and are deciding if they need to get a Masters or Doctorate degree for the job they want. You better be very motivated to get in starting at 22. An alternative is getting in to Integrated Circuit Mask Layout Design. Get in to that and you'll be down in the weeds battlng the process. It's not hard to get in to that and much less schooling but you wind up with lots of schedule pressure because you are in the critical path. If you are good with spatial relations and things like Tetris, packing suitcases, grocery bags and you can understand resistors, capacitors and transistors, you might have the talent for it. With that said you will never have the influence in a company that an EE has even if you design devices and libraries that allow the EEs to design circuits with better electrical characteristics and lower die area. You'll have to reinvent the wheel often because most rookie EEs won't believe that your experience is worth listening to and there is a chance that your job will be replaced by some AI Place & Route tool even if you specialize in full custom analog or you are a guy that runs a Place & Route tool.

Minor correction; at 6:05 you talk about the effects of dielectric permittivity on gate function, and while obviously higher dielectric materials produce a higher capacitance, the electric fields within the substructure are actually *reduced* as an effect of the polarization, which can be essentially described as the realignment of electric charges inside the dielectric that cancels out the external field.
@Martinit02 ай бұрын
So the actual benefit of using high-k gate dielectric would be? Is is that the electric field is lower in the volume of the dielectric but then higher at the interface of dielectric-channel?
@bort64142 ай бұрын
@@Martinit0 Correct, charge density at the gaussian surface of the electrode increases as relative permittivity increases, increasing total work capacity. It's easier to think about when you look at what we consider ,"charge" in electromagnetism as an imbalance of electrons and protons throughout a system. A dielectric essentially acts as a material with quasi-free electrons; similar to a metal, but instead their movement is limited to their immediate surroundings. When an electric field is applied to the material, the charged particles inside rearrange in order to achieve electrostatic equilibrium, which means there is no imbalance of charge, so the field on the inside from the perspective of the system is zero. It also increases charge density disproportionate to voltage, meaning increased efficiency, but I'm not sure how pertinent that is to transistor design specifically. More applies to capacitors and electrostatic motors.

@@aekue6491 I work for a sub contractor for a big international defence contractor. We have long since been briefed that porting existing GAA designs to BPD-GAA will be, and I quote, "a largely automated process for embedded memory and gate logic, but will require substantial consideration and planning ahead of time for analog circuits". Since we work almost exclusively in the boundary layer between analog and digital (such is the nature of real-time signal analysis and shaping) we are currently "a little bit freaked out" as we are in mid-stage design of a GAA based solution that would ideally be finalised and rolled out as BPD-GAA, as that offers vastly superior noise characteristics. However, we are only now starting to get the builtin points on what to account for early to facilitate a reasonably straight forward porting process. Everything is still tightly under NDA from "the big three" but from the gossip I hear the situation is largely identical everywhere: The EDA tools will a breeze for the logic folks (CPUs, GPUs, accelerators, PLCs, FPGAs, etc, etc) but us analog folks (memory controllers, radio spectrum technologies, PCIe/CXL, optic signal modulation, etc, etc) will be the whipping boys as usual. We generally only get good EDA automation and integration of a node once it is no longer relevant for us (aka, once it's mature and cheap enough to make bulk crap products on like wireless doorbells and fridges and what have you). I hope that satisfies your curiosity, as I can't really divulge anything that is more specific than this.

A transistor is not just a switch (on/off). it can also behave like a variable resistor (linear operation). Even if in the field of Digital Electronics, it is always operated (biased) to perform as an on/off switch, the device can also be operated on its linear response characteristics to perform as an amplifier in the analog world. On the input and output sides of a digital circuit we still use transistors as linear devices. After the junction voltage is overcome, there is a nice linear response of changes in current to voltage (smooth changes in input current produces proportional changes of output voltage), before the transistor goes into saturation (completely On). If someone ever invented a true 'digital relay', transistors would become obsolete.

And some time later, after some frustration, they figured it would work better in reverse order, data line first. And the anecdote goes, "we'll never ever talk about this again."

waiting for cpus to use stacking and trying to bump up core counts with out energy counts ones you crystalize a formula in to a transister arrey and lipograpth the function like we want to go as small as possble anyway right?

I've been out of the semiconductor game for a long time. Does anyone have the figures of merit for these transistors?

What FoM are you looking for? As far as I'm aware, unlike with the switch from planar to finfet, the switch to GAA and CFET isn't about individual transistor performance as much as it is about TOR density. As RF designer, everything since 22 nm is a step backwards for my performance (though I hear the high-speed analog guys still get some minor gains).

@JorenVaes I would love to know what the f_t and transconductance looks like. It seems like there is an improvement in output impedance too? I'm just curious how the transistors are better. I haven't seen any numbers for all these nodes, so it's hard to contextualize what's improving and what's the same.

@@ion599I can't comment on Ft, as we tend to not use that that often in millimeter-wave design and work more with Fmax as a metric instead. In general, Fmax has flattend around 300 GHz since 65n, and stayed quite constant until 22 bulk (with exception of 22 FDSOI, which has an Fmax of about 380 GHz). Since finfet, it has dropped back down, afaik the most recent nodes have an Fmax of about 250-ish GHz. This is mostly BEOL limited though - intel has a special 16nm finfet process optimized for RF, and that has a custom BEOL, and supposedly has a crazy Fmax of like 380-400 GHz. I believe a colleague of mine, Carl D'heer, has done some work on quantifying this Fmax over technology in his PhD thesis, but I don't know if this is publicly available.

No one can escape from this game without moving out to the forest in survival mode… because each and every moment of your life the semiconductors are all over the place around you… until you get back into the game and start upgrading your knowledge realizing that the game has never stopped haha 😅 I am personally just an enthusiastic player who is not involved in any kind of design but this show is so fun to watch because it has the best presenter in the industry so seriously conscious and so deliciously funny ❤

@@JorenVaesIt's a shame that the process improvements are not creating faster transistors. It would have been nice to have power gain deep into the THz region. Thanks for answering my question!

I was working in the forklift industry when the first MOSFETs came on the market thirty years ago. They were far more efficient than Thyristors, and took the market by storm. Not quite the same tech, these devices could handle 400 amps at up to 96 volts. Single devices will fill an old style coffee cup, and weigh up to a kilogram.
