Chinese company SMIC has officially achieved volume production of its newest 5 nm-class node called SMIC N+3. This is officially China's most advanced semiconductor node produced without any extreme ultraviolet (EUV) lithography tools, relying on the deep ultraviolet (DUV) to manufacture its silicon...

The source is this paywalled report, the headline of which notably doesn’t go as far as the techpowerup one, though that might just be to bait people into buying access to the full report.

I know very little about fabrication itself, but it seems like the gist is it’s impressive, but pretty expensive and pushing the limits of what’s realistic with DUV. I wonder what the plan is if China still can’t source (or develop) EUV tech soon?

    probably, i remember numbers floating around 7-5 nm transition of like 25 to 35 patterns change (without euv), so in that area
