I'd appreciate it if one of the few people here who know what they're talking about like @FairAndUnbiased and @WTAN could shed some light (no pun) on this question: What's the difference between the light source of an LPP EUVL machine and a laser weapon like the Silent Hunter? Both are around the same power, 30 kW for the MOPA lasers ASML uses (and China is rumoured to have recently developed) and 30-100kW quoted for Silent Hunter.

IDK much about military lasers or ASML lasers in particular, but from my understanding ASML uses a CO2 laser which is somewhat absorbed in atmosphere at 10.6 um. Despite being in a minor atmospheric window the absorption is still much higher than in visible or near IR. In addition higher wavelengths means wider beam divergence, which is the exact opposite of a good drone weapon. You should not use the same wavelengths on an antidrone weapon.

I'd say that for anti drone weapon you'd use a laser in the visible window at near IR, both for low beam divergence and for low atmospheric attenuation, so it'll be a fiber laser, and Silent Hunter is a fiber laser.

TSMC was also late with strained silicon and FinFET. Intel came out with both of those earlier. Samsung does joint process development with the IBM process research lab in the US East Coast and that is why Samsung is ahead in GAA research. But IBM was never known for having good yields with their processes and now Samsung of late seems to be suffering with the same issue. TSMC does not want to jump into GAA too early because they want to solve the manufacturing issues and improve yields before commercializing it.

Apple bow down to pressure, now let's see if other American company will follow suite, Mr Musk you're on the cross hairs and better moderate your political views and opinion cause Uncle Sam is watching...lol

(Reuters) -U.S. tech giant Apple Inc (NASDAQ:

reported on Monday.
Apple had originally planned to start using state-funded YMTC's NAND flash memory chips as early as this year, Nikkei said, citing people familiar with the matter. The chips were initially planned to be used only for iPhones sold in the Chinese market.
It was considering eventually purchasing up to 40% of the chips needed for all iPhones from YMTC, the newspaper said.
The United States last week added China's top memory chipmaker YMTC and 30 other Chinese entities to a list of companies that U.S. officials have been unable to inspect, ratcheting up tensions with Beijing, starting a 60 day-clock that could trigger much tougher penalties.
YMTC is also being investigated by the U.S. Commerce Department over whether it violated Washington's export controls by selling chips to blacklisted Chinese telecommunications company Huawei Technologies Co Ltd.

Biden administration's sweeping set of export controls on China is a bid to slow Beijing's technological and military advances by cutting the country's supplies off from certain semiconductor chips made anywhere in the world with U.S. equipment.
Apple did not immediately respond to Reuters' request for comment, while YMTC declined to comment.

Well looks like is China for the Eurasians now on, US companies heavily absent in the new biddings. With Japan taking more prominence.

[One-week bidding/bidding] Shanghai Jita added 7 new equipment for bidding, Shanghai Microelectronics added 1 new bid-winning equipment, and North China Innovation added 1 bid-winning equipment​

No matter what China will not buy American treasure notes.

I never understood why YMTC did it in first instance.

They have the whole Chinese market to grow, not only Chinese smartphones producers, but also the general NAND market. Even if they double their manufacturing capacity, they would have no problem in selling all their NAND in the Chinese market alone. Why did they choose such a provocative action? IMHO this was a bad management decision.

Certify by Apple is good publicity.

Probably for the world wide prestige, Apple as a brand is known world wide as a brand that sources top parts. So being in a iphone would be a big marketing gain. "If its good enough for apple, its good enough for you"

It's provocative for a Chinese company to solicit for business?
