接近于ASML的1980Di 的国产版,“批量”进入“工艺验证阶段”。

不是SSA800-10哦

写一篇,等着吧。
上次传闻中有对有错,机型和数量都错了。而这次放出来的,是硬货,而且时机是川帝来访前,呵呵
Clearly this is happening and it’s already in use somewhere given the YTMC and CXMT news but the production and delivery number, wafers per hour and type number all seem to be incorrect

well, it's just needed for the most critical layer IIRC?

so basically, this can fully replace 1980i IIRC (although at lower process rate).


Where are you getting this? It's in fact likely that SMEE just concentrate on ramping Arf/Arfi scanner production because their WPH rate is likely lower than that of ASML machines. So, they would concentrate on delivering to top end labs.


if you read the article. It says the machine being used is already at 90-95% yield. Which is quite significant.
And that they are delivering 5-8 in Q2

I guess you can compensate with multiple machines? SSA800 is likely less economical than ASML machines to start off. But given the latter might not have maintenance, seems like worth the trade off.
This SSA800 will get better and better very fast by feedback loop from SMIC, etc, hopefully newer version SSA900 announce soon which is expected to be equivalent to the performance level of the ASML TWINSCAN NXT:2000i and 2050i series. Hopefully in 2027

Is it fair to say that SAA800 is roughly equivalent to the current best Japanese DUVi from Nikon ?

So 2026/2027 is the year when China managed to do complete 28nm process on commerical scale, on all its own?

Is that the right conclusion?

If so, that can be compared to 2013 when various companies in the west achieved said process node? I am sure two are not directly comparable but still...
The 28nm number is only indicative of the machine's ability to etch on a single exposure, all current wafers use multi-exposure techniques to gain a huge accuracy advantage, including EUV machines. If true this will be sufficient to produce every node that SMIC is now manufacturing.

Probably 7 or 8 nm, but I don't think it can do 5nm

28nm planar needs double exposure, the key number is overlay, for 28nm planar is about 8nm, for 14nm Finfet 3.5nm and for 10-7nm is like 2.5nm.

More like article that try to manipulate the stock price.
its cleat that, authorities still don't want to disclose the information so article removed from the website. most likely article draw enough attention.

but one thing is sure, domestic immersion scanner achieved production if we follow SEMICON 2026 and last few months info. now its up to Authorities/SMEE when they officially disclose the scanner with full specifications.
