This 15 minute video is about making feature sizes smaller than the wavelength of the light used. It goes through the history smaller features and shorter wavelengths leading up to OPC, Optical Proximity Correction. Then it talks about the fancier technique ILT, Inverse Lithography technology. ILT requires too much computer power, and Nvidia have found ways to use GPU's to speed it up 42 times.
Nvidia was ordered by the US government to ban export of 4090's to China - because they fear Chinese A.I. research.
But they were given a month (ban starts November 17th). So Nvidia is probably diverting virtually all supply to China while they can. These regulations don't seem to restrict third parties from buying and then reselling to china for a premium. So scalpers have an avenue there.
It looks like Nvidia is saying that there are more reasons for GPU scarcity and price increases, of course it benefits them so they are happy.
