There's no way they'll be manufacturing "3nm" chips this decade without ASML selling them the machines to do so, while this would delay them by months at best.<p>This makes no sense unless the US expects ASML to ship EUV machines to China <i>very</i> soon, because now China will be prepared if they receive such machines later and it likely won't slow them at all. They will know to source materials elsewhere and I have little confidence in software export bans working in this day and age.<p>Surely the US would pick an inopportune moment to yank this away from China to inflict maximum chaos and delay development as much as possible. What prompted this to happen <i>now</i>? Are they about to acquire EUV machines somehow?
> Announced Friday by the US Commerce Department's Bureau of Industry and Security (BIS) and enacted today, the rule will ban the export of two ultra-wide bandgap semiconductor materials, as well as some types of electronic computer-aided design (ECAD) technology and pressure gain combustion (PGC) technology.<p>> In particular, the BIS said that the semiconductor materials gallium oxide and diamond will be subject to renewed export controls because they can operate under more extreme temperature and voltage conditions. The Bureau said that capability makes the materials more useful in weapons.<p>Do SaaS providers of these kinds of software now have to kick off Chinese customers?
Pressure Gain Combustion tech was a very promising approach to increase the efficiency of planes, gas turbine power stations, rockets, and many other fields.<p>An export ban effectively kills all that tech.<p>Banning efficiency improvements like this isn't exactly great for the environment. People will just keep burning coal.
I expect China to have its own EUV machines in the next few years.
Any bans will only serve to convince the Chinese government to give more money to their scientists.
