Under the huge external pressure, it is necessary to build a domestic semiconductor industry chain with self-reliance. So how long will it take us to support most of the demand without us technology? The crisis has always been the coexistence of danger and opportunity. Although the current situation is quite grim, China has never lacked the ability and confidence of independent R & D and innovation. Objectively, the restrictions of the United States have also created a good opportunity for China’s semiconductor industry to develop and improve its industrial chain. < / P > < p > on the one hand, under the background of the revision of export control rules by the United States, the participation of international monopolists has been reduced, and the demand of domestic semiconductor industry for domestic equipment and materials has also increased. As long as they can be made, they will not worry about selling, which has greatly stimulated the enthusiasm of upstream Chinese companies. On the other hand, the government is vigorously promoting the localization of China’s semiconductor industry, and has given many favorable policies. On August 4, the State Council issued several policies to promote the high-quality development of integrated circuit industry and software industry in the new period, which mentioned that the integrated circuit manufacturing enterprises or projects with integrated circuit width less than 28nm (including) and operating period of more than 15 years encouraged by the State shall be exempted from enterprise income tax from the first year to the tenth year, and those with 65nm (including) encouraged by the state and operating for more than 15 years shall be exempted from enterprise income tax Integrated circuit manufacturing enterprises and projects are exempt from enterprise income tax from the first year to the fifth year and reduced by half from the sixth year to the tenth year. At the same time, capital is pouring into the semiconductor industry. According to it orange data, in the second quarter of this year, capital investment in the chip industry increased nearly 10 times year-on-year and 65% month on month. Some companies even obtained more than 1 billion yuan of investment in the early stage of entrepreneurship. According to the incomplete statistics of Zhidong, from the second quarter of this year to July 23, there were 77 semiconductor investment and financing transactions in China’s primary market. The total amount of open transactions reached 26.7 billion yuan, and a total of 72 semiconductor companies were invested. SMIC also attracted a large number of institutional and strategic investors when it went public in July. In addition, Chinese companies are also actively recruiting talents. The Nikkei Asia review reported in August that since last year, more than 100 experienced engineers and managers have been recruited from TSMC by two government supported chip manufacturers. In fact, a lot of good news has been spread out in China’s semiconductor industry. For example, in terms of the most core equipment and the most mentioned lithography equipment, recently, it is reported that Shanghai microelectronics will deliver the first domestic 28nm lithography machine in 2021. In many people’s opinion, 28nm process technology is far from 5nm and 7Nm, but in fact, as the dividing point between mature process and advanced process, 28nm can meet most of the current market demand, such as industrial manufacturing in Internet of things, home appliances, communication, transportation, aerospace and other fields, in addition to mobile phones and computer chips which have strict requirements on power consumption and size 。 < / P > < p > from the global wafer foundry capacity distribution in 2019, including the annual import of 300 billion US dollars of chips in China, we can see that the process above 28nm is the mainstream. This means that once we fully master the 28nm chip manufacturing technology, we can largely meet the needs of domestic development. < / P > < p > recently, many analysis institutions and media have carried out an inventory of the key equipment and materials involved in the chip manufacturing process, as well as when their domestic substitutes can be realized. It is found that most of the equipment and materials have basically no technical problems at the 28nm node. The bottleneck lies in the lithography machine and photoresist, and the latter is expected to achieve 28nm in 1-2 years The landing of production line. < p > < p > in the past few decades, the global semiconductor industry chain has been closely divided and cooperated, and a professional cooperation mode of vertical division of labor in chip design, OEM manufacturing and equipment supply has been formed. The main chip design companies are concentrated in the United States, China, Europe, Singapore, Japan and Taiwan, and chip manufacturing is mainly concentrated in China, South Korea, Japan, Europe, Singapore and Taiwan, which are interdependent and highly dependent. Chip manufacturers all over the world widely use chip manufacturing equipment from different countries, some of which rely on the United States. < p > < p > the practice of the United States has destroyed the trust foundation of global cooperation and caused serious harm to the international semiconductor industry. A large number of rational institutions and people abroad have criticized this and called for further cooperation. According to Japanese media reports, the ban on Huawei may cause Japanese enterprises to lose as much as 1 trillion yen; the American Semiconductor Association and the international semiconductor association have also expressed concern about the US government’s practice, which has also imposed huge restrictions on the chip sales of American enterprises. With the vigorous promotion of the government and the strong demand of the 1.4 billion population market, the localization process of the upstream and downstream of the domestic chip industry is accelerating, especially the 28nm domestic industrial chain is expected to mature after 1-2 years of efforts, which provides strong support for the construction of a new development pattern with the domestic big cycle as the main body and the domestic and international dual cycle promoting each other.
