I remember the X90 teardown now. I hadn't known it had been promoted by the state as 5nm the month before. The teardown must have truly caused some embarrassment, TechInsights now blacklisted in China. But what's more significant is whether Huawei itself had considered X90 any generation beyond...
Xiangdixian is the key player here; it almost dissolved last year, but apparently got bailed out by Anfu (a battery developer?), probably with government arrangement.
At its website, Xiangdixian maintains it is doing domestic GPU production; it previously used 12nm, which likely came from TSMC...
This development, which happened a little over two months ago, may not signify much in the GPU world (compared to Huawei and NVIDIA obviously), but a 5nm GPU tapeout in China at this point is significant, since last November TSMC and Samsung have stopped shipping AI-related chips at 7nm and...
On September 3, Anfu Technology stated on its interactive platform that the new generation "Fuxi" architecture chip developed by Xiangdi has completed tape-out verification. The chip performs excellently in terms of graphics rendering capabilities and parallel computing performance.
It is...

With speculation mounting that former TSMC SVP Wei-Jen Lo may have taken key materials to Intel, the company’s CEO Lip-Bu Tan has spoken out in response...
EUV is less predictable than previous litho technologies, because it is fundamentally a stochastic process. A lot of money will be burned.
Unfortunately, some of the thinking behind not using EBL, which found the need to use Monte Carlo simulations, did not get used.

It has no US patent applications since 2017, based on assignees list here: https://patents.google.com/?q=(X-ray+lithography+optics+pattern+wafer+nm)&country=US&after=priority:20170101&oq=(X-ray+lithography+optics+pattern+wafer+nm)+country:US+after:priority:20170101
"These bright pulses of light are transported and shaped by a succession of perfectly polished optics all the way to the silicon wafer."
The missing piece is the mask, or reticle.

Apparently, he will not sell this to TSMC, he wants to create his own US-based foundry to compete against TSMC. I suppose he will even compete against Intel.
I noticed his setup lacked any radiation hazard signs, which should be required for X-ray accelerators.
The single-layer prints aren't any better than something that can be done by nanoimprint, which leads to the question of how to control overlay, among other things.
X-rays also have worse...
