Chip manufacturing difficulty. The first level, mask aligner, stumped China, because foreign countries have never sold high-end mask aligner, we have our own low-end, and the best in mask aligner is only 90 nanometers. The second level is chemical materials, that is, Japanese sanctions rods, which are not easy to do, especially high-end photoresists. We can only produce low-end products. Low-end photoresist can only be used in low-end lithography process, and 7 nm, 14 nm process can only be used in high-end third wafer pass, that is, monocrystalline silicon wafer. The related equipment, such as laser cutting and silicon rod production equipment, is not a fourth-level design that can be built with large investment. It takes many iterations to reach maturity, and the fifth-level market is not built, with high cost and no competition at all. The sixth-level software ecosystem, without architecture and authorization, cannot be compatible with existing software systems. The previous Loongson can only be used for military purposes. It is invisible in the market. The seventh level is the process level. This technology is constantly improving, the cost is getting lower and lower, and the old technology is expensive and uncompetitive. The eighth level of funds, 10 billion has just started, and it is not difficult to advance10 billion. The ninth cancellation. It didn't start in 65,438+00 years, and there will be no mature products on the market. Kirin series has been making chips for 15 years now. Years of accumulation have led to today's success. Ten-level talent clearance, this line of talent is very precious, can not be taught in school. China is even rarer if it is cultivated by enterprises. Most of them invited China scientists from abroad or Taiwan Province province.
Manufacturing in mask aligner is very difficult, so few countries can produce cutting-edge mask aligner. ASML, the Netherlands, is the height that can be achieved by concentrating the technical talents of Europe, America and even Japan. China people are the smartest people, and the nation with the most scientists in the world is China people. National will, national will, capital, technology and talents, combined with China's strong will, will surely overcome difficulties and make mask aligner the top in the world.
