I think technically there is no such thing as a single number that describes a lithography process any more.
Yeah, the boundaries of the UV light will put it from 11-14 and the physical photons they emit will average 13.5nm with some ridiculously small margin of error
Yeah, but if I'm understanding you correctly then I would argue that you can't say the following:
Because using that reasoning everything before EUV was all 193 nm process since all of the high end processes such 10nm, 14nm, 28nm, etc etc nodes used a 193nm source.
Not quite the ASML 3300B and 3350B are what Intel used for its 14 nm through 14+++++++++nm process and it ranged from 22nm down to 16nm towards the end. ASML's precision work comes from how much they have managed to narrow down the EV spectrum, the first lasers in the 1960s were using a 435nm mercury laser for carving out ICs, it's all about tightening up the very small usable portion of the spectrum too as narrow as they can get it and focusing it as tightly as they can, which is where their lenses come in. But the point stands the numbers matter but the names are made up and nothing means anything.
Hmm? Intel 10nm and 14nm are 193nm lithography.
Intel used the ASML 3300B at the start of their 14nm stage, which at release was 22nm, as time went on it was tightened up to 18nm with the replacement of the lasers and lenses which as burnt up over time as they get used. The 3350B is what Intel uses currently for their 14nm and 10nm process and ASML advertises that as a 16nm photon, with some sort of magic mumbo jumbo and angles.
I either disagree with a lot of your posts in this thread, or am misunderstanding what you are saying. EIther way I guess I've probably derailed this thread enough, so I'll stop.
I’m probably not explaining it well, but there’s no good way to that I know of. But Intel until now has not been using EUV processing which TSMC has been using since 7nm.
Yeah point is Intel, TSMC, Samsung, and ASML all seem to use different metrics to determine the actual size of the nodes. So don’t pay attention to it. But Intel’s purchase of the next 2 years supply of ASML’s latest and greatest 5500 EUV units is how they finally pass TSMC in the race because TSMC can’t physically take delivery of similarly classed equipment until some time in 2025 with them getting online in 2026.
