In the field of integrated circuit manufacturing, TSMC is the dominant company, accounting for about 60% of the global market share, leaving the remaining domestic companies with less market space. The reason is that China's integrated circuit manufacturing level lags behind the international advanced level by more than two generations, and the lack of advanced processes limits the development of integrated circuits in new application areas. At present, TSMC and other companies have mass-produced 7nm processes. SMIC has begun to lag behind at the 28nm node. It is currently expected to achieve 14nm mass production in the first half of 2019. After achieving 28nm mass production, Huahong is actively deploying 14nm R & D.

In the field of raw materials, silicon materials have a high monopoly. More than half of the global semiconductor silicon material production capacity is concentrated in Japan, especially as the size increases, the monopoly situation becomes more serious. The total share of the world's top five semiconductor silicon fabs reached 94%. China's self-produced silicon wafers are mainly 8 or 6 inches. The main application areas of products are still photovoltaic and low-end discrete device manufacturing, while 12-inch large-scale integrated circuit-grade silicon wafers still rely heavily on imports.

The field of integrated circuit equipment is a highly monopolized market. According to the statistical data of market share of each segment, in the field of lithography machines, pVD, etching machines, oxidation, and diffusion equipment, the total market share of the top three equipment manufacturers has reached More than 90%.

The problem of designing and manufacturing "two ends out" is still continuing. China's manufacturing industry is developing rapidly, but it is mainly for OEMs of overseas customers. Under this background, expanding the production capacity of domestic OEMs may not directly increase the self-sufficiency rate of domestic chips. Some projects will face huge risks.

On the whole, there is a problem of low overall capital expenditures in the integrated circuit industry, and investment tends to expand production capacity expenditures rather than technology upgrade expenditures. Therefore, it has further caused problems in the design field and manufacturing field with fewer technical bright spots and backward manufacturing processes. On the other hand, in the manufacturing field, the monopoly of raw materials and production equipment has further increased the uncertainty of industrial development. Therefore, industrial drawbacks still exist, and there is a long way to go for development.
