At present, the domestic semiconductor industry has not fully realized the 22nm level of chip manufacturing, so whether the domestic lithography machine can really break through the 22nm level of manufacturing is still controversial. However, domestic semiconductor equipment manufacturers are actively carrying out related technology research and product development, such as micro semiconductor, Naura and other companies have carried out a series of technological innovations and breakthroughs in the field of lithography machines, and continue to improve the resolution, processing accuracy and production efficiency of their equipment. With the continuous development of the domestic semiconductor industry and technological progress, it is believed that domestic lithography machines will also achieve 22nm level chip manufacturing in the future, and play an important role in the global semiconductor equipment market.
No breakthrough to 22 nanometers.
The current energy production process of the domestic lithography machine is 90nm, which is a device manufactured by Shanghai Microelectronics, which is also one of the four lithography machine manufacturers in the world. The 28nm lithography machine of Shanghai Microelectronics Company last year has passed technical testing and verification, and is expected to be provided to the purchaser this year. The lithography machine of 22nm process should not be included in the company's plan.
