That would be annoying for someone living in the US. Imagine paying medical bills associated with one extra limb in with their disaster of a health care system.
DeSantis wants to raid Canada for its more-affordable prescription drugs.
The connection to tech in this comment is extremely tenuous.
Back to the topic... people were musing about future transistor tech. I have been waiting for some sort of gallium arsenide since the Cray III. How about creating a machine that can build transistors from such a molecule — molecule by molecule? This will remove all of the defects and maximize the density. There has been talk about nanowires but it all seems very messy.
I truly wonder when this "race to the bottom" will run out of steam and FET transistors of any kind will need to be replaced with a new tech due to physical and/or quantum mechanical limits.
GAA-FETs are almost certainly not the last FET tech, TFETs (TunnelFETs) are next. These exploit quantum tunneling, which in traditional MOSFETs is a hindrance, since it increases leakage.
Hence they also overcome the 60 mV/decade of current limit, which is a fundamental limit of MOSFETs. And since they work via quantum tunneling they work best with super slim gates - which, again, does not work well with conventional MOSFETs.
Then what though? Are TFETs the last FET transistors? If so what tech will replace them?
in all likelihood, for general deterministic computing, nothing. the so-called quantum computer works only for a miniscule niche of problems. ya ain't gonna run your GL on a computer that guesses at the bottom line.
Probably nothing. We reach the limit of what we're capable of with transistors within the universe's laws of physics. We'll have to find a completely new way of computing I guess.
I got a question. Does this High-NA EUV equipment improve on the feature resolution at the same node size? Or, in their promo slides, are they talking about a presumed size node shrink in conjunction?
I'm afraid that's rather a confused question; 'node size' and 'feature resolution' are pretty much the same thing, 'node size' is a marketing number referring to a complex specification which includes feature resolution.
The two got divorced a long time back. The marketing term of node size has merrily been partying on fast track, while the more mundane feature resolution stayed home and kept things real.
AFAIK it always has been called "High-NA" Why is it called that? Because the main change between the previous machine and newer one is the higher Numerical Aperture.
They enable finer detail with each mask so you can keep doing complex features with single patterning on smaller nodes than with the earlier scanners, which keeps the processing times and therefore cost down. Multipatterning is expensive and increases the processing time.
Please call it something like '0.55NA optics' rather than 'a 0.55NA lens' - there are no lenses in EUV lithography, a lot of what makes it difficult is that essentially everything absorbs EUV light, so the whole light path needs to be in vacuum, and you need exquisitely complicated multi-layer coatings even to reflect it.
Diffractive lenses are still lenses, and in the EUV regime you're phase-shaping diffraction more than you are 'reflecting' as with mirror lenses. Even DUV lenses already include diffractive and reflective elements.

While funny, the "health care system" is doing precisely what it's designed to do: make massive amounts of money.It has little to do with "health", and hasn't for a very long time.
