Taiwan Semiconductor Manufacturing Company (TSMC) announced a number of node scaling details and technological advancements at its 2020 Technology Symposium:

TSMC's first "5nm" node (N5) has a lower defect rate than its initial "7nm" node did at the same point in its development cycle (high volume manufacturing, which N5 is now in). This is due in part to increasing use of extreme ultraviolet lithography (EUV). "5nm" will represent 11% of TSMC's sub-"16nm" wafer production in 2020.

TSMC's "3nm" node (N3) will continue to use FinFETs rather than gate-all-around (GAA) transistors, and is scheduled for volume production in mid-late 2022. Performance is expected to improve 10-15% at the same power (compared to N5), or power consumption will be reduced 25-30% for the same performance. Logic area density improvement will be 1.7x, but SRAM density will only increase by 1.2x, leading to a 1.27x overall density increase for chips that are 70% SRAM and 30% logic.

Intel's EMIB (Embedded Die Interconnect Bridge) connects "chiplets" together without using a full silicon interposer. TSMC has its own version that it is calling Local Si Interconnect (LSI), and it will be combined with other packaging technologies. TSMC has demonstrated 12-layer stacking of chips using through silicon vias (TSVs), although cooling or doing anything useful with them could be somebody else's job.

    Only computer nerds would brag about how small their pipes are. Of course, when they reach the Quantum Realm, like AntMan, all bets are off.

        You do not know your Greeks, especially your Samians! Try Ευπαλίνιον όρυγμα [wikipedia.org]. Greeks have pipes. Where do you think the God Priapus [wikipedia.org] is from?

        Oh, you lesser northern Europeans, or residents of the more southern realms! You really all wish you could be Greek men, and so do all your women. Tis true.

    That's what she said.

    I should have dumped her before she dumped me.

      So much for SoylentNews being a tech site, with salsa, a replacement of the un-named. Instead we have Runaway, the Rejected, and TMB, the irrefutable, and no rational discussion of the reductions of pathways in silicon. I blame Janrinok, for banning the aristarchus submissions that could have forestalled this alt-right takeover.

        So says "3nm-pennis" AC, hehehe.

    Extreme Ultraviolet lithography.

    I understand the concept of smaller spectrum of light, but I don't understand the mechanism that controlls the light more accurately than the size of the particle wave itself. In my mind it's like a chicken and the egg conundrum.

    For some perspective, that's approximately the width of ten water molecules, or 50 hydrogen atoms.
