It immensely help to propel Chinese semiconductor industry forward. Last year when Mate 60 series was launched, the Kirin 9000S chip it used was fabricated with a de-Americanized production line. Such production line could still use foreign equipment, material and process, such as those from Netherlands and Japan, with a mix of domestic supply chain.

Around the time Pura 70 series was launched, ie. about two months ago, the domestic production line has completed and came online. By complete, I believe it mean certified in real world production. Which suggest that the Kirin 9010S chip used in Pura 70 Pro could be fabricated with full domestic process, including the domestic lithographic machine.

About two months ago, after Pura 70 launch, there was an analysis of the Kirin 9010 chip. While it was found that Mate 60’s 9000S is clearly manufactured using ASML machine as the Athena AH74 scribeline mark is clearly present. On the 9010 die, there is none of the ASML scribeline mark, from ancient TTL to Athena and SMASH.

Not only ASML machine, the LSA, FIA scribeline mark of the Nikon, TTL, OAL of the Canon are also not found on the 9010 die.

The conclusion at that time is, there's no evidence that 9010 is fabricated by ASML lithographic machine. What lithographic machine is used is unknown. Now with the revelation of the domestic process being completed around that time, it's very likely to be a domestic lithographic machine.

The 9000S and 9010S are manufactured with the same 7 nm process, they shared a lot of commonality, all components are exactly the same except the CPU cluster. Why would 9000S has clear ASML scribeline mark while 9010 has none? The simplest explanation is it wasn't fabricated with ASML, Nikon or Canon lthographic machine. Then the question is what machine is used?

The US not only banned ASML from selling EUV lithographic machine. Later on they also banned DUV machine. Then later on they pressured ASML to stop maintenance support of existing DUV machine bought before the ban, after finding out Huawei could still make 7 nm chip using DUV machine. This is in clear breach of contract, goes to show how much worth is signing contract with the West, they’d easily breach any contract they sign without making repatriation. It’s easy to understand the need of not only de-Americanized process, but a full domestic process. Now they can talk more openly about what chip are used in Huawei phones.
