Recently, the U.S. Department of Commerce issued an announcement announcing that 36 Chinese high-tech companies and R&D institutions will be included in the U.S. export control “entity list” to continue to expand the crackdown on China’s semiconductor industry. As soon as the news came out, many people noticed the well-known domestic memory chip company YMTC, but at the same time, everyone may have overlooked another key company on the list-Shanghai Microelectronics.

Shanghai Microelectronics — the light of China’s lithography machine industry
Many people may not know that Shanghai Microelectronics is currently the most advanced lithography machine company in China. The 600 series lithography machines it produces can reach a maximum process of 180nm, occupying a high market share in the entire domestic market.
In addition, Shanghai Microelectronics’ 6000 series lithography machine technology is also very mature. Its process technology has reached 90nm, which is of great help to the R&D and manufacturing of domestic low-end chips. Therefore, it can be said that Shanghai Microelectronics has a very high status in China’s lithography machine industry, similar to SMIC among chip foundry companies, and they are all important presences in their respective fields.

The development progress of domestic lithography machine is dragged down
Although Shanghai Microelectronics is one of the largest lithography machine companies in China, it still has a big gap with ASML and other international lithography machine giants, and some key parts are still controlled by other countries.
It is reported that some of the main components of Shanghai Microelectronics lithography machines come from American component suppliers such as MKS, and the localization rate of these components is very low. In addition, components are a small and beautiful track that tests basic research and long-termism. Its technical barriers are extremely high, and the possibility of domestic suppliers replacing American suppliers in the short term is almost zero.
But now the United States has officially ordered Shanghai Microelectronics to be banned, preventing Shanghai Microelectronics from buying any American technology, equipment and raw materials. This will cast a shadow over the development of domestic lithography machines. You must know that as early as 2020, according to media reports, Shanghai Microelectronics disclosed that it will deliver the first domestic immersion lithography machine with a 28nm process in 2021-2022, but now 2022 is coming to an end, and there is no waiting for Shanghai. The news of the first domestic immersion lithography machine with a 28nm process delivered by Microelectronics, but the news that Shanghai Microelectronics was completely banned by the United States came, which is unavoidably sad.

It has to be said that this trick of the United States is really poisonous enough to block one of the largest lithography machine companies in China, which will hinder the development progress of domestic lithography machines. Without lithography machines, domestic chips will inevitably be greatly affected. Perhaps the most Hard times have come. It is worth noting that this is not the first time that the domestic lithography machine industry has been suppressed!
The domestic lithography machine industry has been suppressed many times
The CEO of ASML once said that China could not manufacture EUV lithography machines even if the drawings were made public; Eric Johnson, CEO of Japanese photoresist supplier JSR, also pointed out that China could not master It is based on extreme ultraviolet lithography, or a complex chip-making process known as EUV lithography.
The CEOs of the above two companies both overtly and secretly looked down on China’s ability to manufacture lithography machines. But in fact, China did not start late in the R&D and manufacturing of lithography machines, and was once at the same level as the world’s top lithography machine manufacturing level.

As early as 1966, No. 109 Factory and Shanghai Optical Instrument Factory jointly developed the first 65-type contact lithography machine in domestic history. After the successful development, Shanghai Radio Special Equipment Factory put it into mass production. In 1985, the 45th Institute of the Ministry of Electronics successfully developed and manufactured the first distributed lithography machine in China: BG-101! It is worth mentioning that at this time, the gap between the manufacturing level of China’s lithography machines and the top international level is less than 7 years.
Unfortunately, it changed in 1996, when more than 30 countries signed the “Wassenaar Agreement”! According to the agreement, the semiconductor technology and lithography equipment exported to China are required to be two generations behind the most advanced international technology in the same period. In addition, at that time, China had no surplus funds to spend on the independent research and development of lithography machines, which led to an infinite gap with foreign countries again. In addition, in recent years, the United States has unreasonably suppressed domestic lithography machine companies such as Shanghai Microelectronics. , The domestic lithography machine technology seems to have reached the point where it cannot catch up with the top international level.
