Earlier quoted context omitted.

The term "5 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. It is a commercial or marketing term used by the chip fabrication industry to refer to a new, improved generation of silicon semiconductor chips in terms of increased transistor density, increased speed and reduced power consumption. https://en.wikipedia.org/wiki/5_nm_process It i…

IMO GiB and gigabit are deliberately consumer-confusing terms with an even clearer standard definition.

Same with 4K, prior to it the number was used to describe the height of the screen (480, 720, 1080) but then 4K describes the width which confuses people into thinking it has 4x the resolution of 1080 when it’s really 2160 (double the resolution.)

> i don't believe in physical limits for computation there are limits, we're just not close to them. https://en.wikipedia.org/wiki/Limits_of_computation > when i read about 50MHz being the fundamental impossible to surpass limit yeah i think the problem here is popular press writing

some of those limits are applicable to black holes only in the state of thermodynamic equilibrium. The miniature unstable black holes/singularities produced using quark-gluon lithography may be not a subject to those limits, and miniature wormhole loops through 4th dimension may prove to be an effective workaround for storage limits, etc.

i hope that any of that has any bearing on engineering practice in our lifetimes.

That "1nm" is complete marketing bullshit, like it always was, for a decade or two. Silicon lattice step is ~0.5nm, so 1nm is at most 3 atoms. Current technology is definitely not there yet however we're getting closer. Very interested what marketing department will say after 1nm became old news

It's a random number in front of physical measurement, unrelated to anything from reality.

Just because all of the marketing departments choose to participate in this particular bs doesn't mean it's not pure marketing bs. That just means it's industry standard marketing bs.

Double the linear resolution. 4x the pixels.

I'm confused - the whole point of this paper appears to be reporting a gate composed of a 2D monolayer of atoms as opposed to a 3D bulk deposition. So it seems like it is "there" in the sense you mean?

Abstract: Advanced beyond-silicon electronic technology requires both channel materials and also ultralow-resistance contacts to be discovered1,2. Atomically thin two-dimensional semiconductors have great potential for realizing high-performance electronic devices1,3. However, owing to metal-induced gap states (MIGS)4,5,6,7, energy barriers at the metal–semiconductor interface—which fundamentally lead to high contact resistance and poor current-delivery capability—have constrained the improvement of two-dimensional semiconductor transistors so far2,8,9. Here we report ohmic contact between semimetallic bismuth and semiconducting monolayer transition metal dichalcogenides (TMDs) where the MIGS are sufficiently suppressed and degenerate states in the TMD are spontaneously formed in contact with bismuth. Through this approach, we achieve zero Schottky barrier height, a contact resistance of 123 ohm micrometres and an on-state current density of 1,135 microamps per micrometre on monolayer MoS2; these two values are, to the best of our knowledge, the lowest and highest yet recorded, respectively. We also demonstrate that excellent ohmic contacts can be formed on various monolayer semiconductors, including MoS2, WS2 and WSe2. Our reported contact resistances are a substantial improvement for two-dimensional semiconductors, and approach the quantum limit. This technology unveils the potential of high-performance monolayer transistors that are on par with state-of-the-art three-dimensional semiconductors, enabling further device downscaling and extending Moore’s law.

No, it isn't random either but it hasn't been associated with a particular physical feature size since 1997.

0.8nm. Something TSMC stated they intend to bring to market by 2030.

Yes it is marketing term. But I thought everyone should know that by now.

HD ~= 1080p ~= 1K. 4 x 1080p ~= 4K.
