You still haven't read the article. *Sigh*, it seems I'll have to take time out of my day and educate you once again. Not that you'll learn anything, so this is more for the benefit of other readers.
If you bothered to read the article, you'd know that China has put in decades - it's been researching extreme ultraviolet lithography for three decades. The tech demonstrator mentioned in the article is the culmination of that work.
The great (for me) part is that all of the machine's components: the light source, the lenses and mirrors, and the workpiece are all indigenously sourced. 100% Chinese, 100% sanctions proof, 100% available for use by all those countries like Russia and Iran that have been bullied by the US and excluded from access to modern technology. They'll be able to use SMEE's machines, and China's complete semiconductor toolchain from design to manufacture, to create whole new generations of military electronics. Isn't that swell?
It's so adorable that you think China's planning to do anything as pedestrian as "competing" with ASML - China is going to drive ASML and TSMC out of business. It's going to make any kind of commercial semiconductor activity outside its borders untenable. You think Trump is some mafia gangster because he shook down TikTok? He's nothing more than a two-bit thug. China's going to show you what real mafiosi thuggery is all about.
China is already the world's assembly point for all semiconductors.
Everything finds its way into China at some point or other. Once China has attained complete semiconductor independence for itself, it will turn around and present every single electronics manufacturer around the world with an offer they can't refuse: either shift
all of their semiconductor sourcing to SMIC and other Chinese fabs, or forfeit the gargantuan Chinese market entirely and exit China. And don't think "exit China" means anything for them other than dying outside in the cold.
