An interesting set of data was found in the customs statistics
Semiconductor exports to Russia is double in 2022, and the data drop in 2023, but it will still be much higher than before 2022.
In 2019, the export value was 45 million US dollars
In 2020, exports worth $55 million
$72.61 million in 2021
2022, $175 million
From January to June 2023, $66 million

Offline Lithography Process Stability Control Method Based on Image​

Bowen Xu Shanghai IC R&D Center, Shanghai

Abstract: In the lithography process, the stability of lithography conditions plays a key role in the stability of the image quality on the wafer after lithography. For the monitoring of the stability of lithography conditions, the current practice is to use a scatterometer and a specially designed grating pattern to infer the actual process conditions of lithography from the scattering profile curve. This approach requires special scatterometry tools and is sensitive to layer changes in the film stack beneath the photoresist. In order to solve the above problems, this paper proposes an image-based off-line photolithography process stability monitoring method. For the first time, the method of using neural network is proposed to extract the characteristic information of CDSEM images under different lithography processes, and make one-to-one correspondence with the aerial images. This method replaces the method of using a scatterometer to observe the image after lithography, and avoids the actual lithography process, which is of great significance for the detection of the stability of the lithography machine on the production line.

It's widely embraced because it is both objective and correct. Without EUV, the Chinese semiconductor industry hits a hard stop no matter how capable other parts of it are, and truth be told the DUV lithography part isn't great either.

It would be better if the author wrote about the progress being made here and when a completely indigenous supply chain will be ready rather than some cope about lithography being secondary and a non-sequitur about AI. AI doesn't run on air, it runs on semiconductors - very capable ones - and Chinese AI will be hobbled if China can't supply itself with the semiconductors it needs.

If there is essentially a complete external embargo on semiconductor and IC chips making equipment and materials such as deposition, etching, implantation equipment and also photoresists, having and knowing how to produce EUV machines will not produce any chips when all the aforelisted items and others not mentioned are necessary for the production of chips. One shouldn't be dismissive of other items.

Imagine the frustration in the US semiconductor industry reading something like this, the problem with this people is that they have EUV engraved in their heads, they think that everything is ASML.

That's not the point that should be made, that concedes EUV to them. The point is China is 80% of the way to the James Webb Space Telescope.
