The Kirin 9000s chip is made by Huawei itself, so the lithography machine is also made by Huawei itself. Huawei has its own research and development team and production equipment in the field of chip manufacturing, including lithography machines. The lithography machine is a very important device in the chip manufacturing process, which is used to project the circuit pattern onto the silicon chip, ensuring the precise manufacture of the chip. As the world's leading communications technology company, Huawei has advanced manufacturing capabilities and technical strength to independently produce high-quality lithography machines to meet the manufacturing needs of Kirin 9000s chips.
