Whether a chip exists or not, and the approximate process, is pretty straightforward. You do a SEM cross section and check parameters like CD, metal layers, FinFET or not, etc.
Other things may be derived parameters and are a bit more nebulous.

Ah yes, actual research papers, bidding data and sales numbers are exactly like that. Holy shit lmao.
Interesting article. I have no idea if it has already been shared?
“The still-unstated goal is to keep China two to three generations behind U.S. and other western companies in the manufacturing space,” Triolo said. “But the actual impact of new controls being considered, including for deep ultraviolet lithography, previously uncontrolled, is to give the U.S. government veto power over what any new foundry in China can produce.”
The U.S. plans to implement the controls with its international partners under a pact dating back to the Cold War known as the .
The new rule has been “coordinated via the Wassenaar Agreement, so it would be multilateral in nature,” Triolo said. “In terms of companies that could be affected, for this particular rule, it is the EDA tool makers that would be most affected, here Cadence, Synopsis, and Mentor. However, the wording of the rule remains unclear, and as written, the industry is pushing back because it is not clear that advanced versions of EDA tools can have GAA capabilities disaggregated from the overall software package.”

These two statements are not mutually exclusive.
This is ineffective though. It's all or nothing. If I were the US government I would do either:
1. have no tech restrictions and use market and media propaganda to let biased self haters keep Chinese semiconductor industry separate from each other and dependant on both foreign customer and supplier
2. full immediate decoupling like a semiconductor Pearl Harbor and let the chips (lol) fall how they may .
The slow approach that tries to have both profits and restrictions just gives forewarning of what areas China needs work in.
The boys from Jinhua are getting some local OCD equipment, usually KLA where the ones supplying this equipment until the sanctions.
Shanghai Jingce Semiconductor Measurement Equipment won the bid for Fujian Jinhua Memory Construction Project
Shanghai Jingce Semiconductor is a holding subsidiary of Wuhan Jingce Electronics. Shanghai Jingce has achieved technological breakthroughs and industrialization of semiconductor testing and process equipment through independent construction of R&D teams and overseas mergers and acquisitions to introduce localization, so as to quickly become bigger and stronger. In July this year, Shanghai Jingce Optical Critical Dimension (OCD) measuring equipment EPROFILE300FD once again passed the 28nm process verification of key customers, successfully entered the mass production line and put it into full use, and was highly recognized by many customers. The successful application of this equipment not only fills the gap in the domestic semiconductor measurement equipment field, but also makes Shanghai Jingce the only OCD measurement equipment supplier in this field in China that has been successfully applied to the customer's large production line.

so, can China ban the sales of nVidia chip to the US defence that partly developed in China ?

but, who manufacture the chip?
That seems pretty important. To quote KLA "As each layer in a chip is constructed, the Archer 750 helps verify that pattern features are correctly aligned to features on previous layers, while the SpectraShape 11k monitors the shapes of three-dimensional structures, such as transistors and memory cells, to ensure they remain in spec". Which broad category does that fall under?
