According to reports, Shanghai has announced that it can mass-produce 14 nm chips, and there are few manufacturers with this core technology in the world, which is obviously the basis and source of confidence for China's chip technology to take off. There are also manufacturers working on 7 nm and 5 nm chips. This shows that China's chip research and development has approached the world's advanced level. In this case, the focus of China's chip research and development has shifted to 28 nm chip manufacturing, but no longer mentions 7 nm and 5 nm.
The 7 nm process is obviously more advanced, so why not do more in-depth research and development in this area? What about mass production of this? In fact, the reason behind it reflects the wisdom of big countries.
As we all know, although TSMC can also produce 3 nm chips, but due to the small number of orders, it is simply not enough to support his huge profit demand, 7 nm is also facing this situation, although it can produce, but it is not enough to achieve mass production, the continuous reduction of orders, so that this chip production can not provide huge profits, so it is not TSMC's most important business.
Faced with this situation, even if SMIC has been able to produce 7 nm chips, but due to insufficient mass production, it cannot improve quality and increase production at the same time, which is due to the market environment, coupled with TSMC's advantages in product quality, so SMIC decided to suspend 7nm mass production research and development. In addition, considering that the United States has been suppressing the development of Chinese chips in various ways, but also restricting the export of semiconductor equipment, after all, the domestic demand for such high-end chips is limited, if it cannot open the international market and cannot be exported to other countries, the research and development of high-end chips will also be full of risks.
SMIC decided to focus its R&D on mature chip R&D, so it invested heavily in expanding production, hoping to be self-sufficient through domestic chip manufacturing, while counter-exporting to the international market. Moreover, new energy vehicles have a huge demand for mature industrial chips, and in the face of a huge market, SMIC seizes the opportunity to promote the rapid growth of mature chips, improve the yield rate, and improve the competitiveness of the international market.
So far, SMIC's 28 nm chips have a very mature technology and can compete with international famous manufacturers. After all, the global demand for mature chips is huge, which can support a company to obtain huge profits. But at the same time, SMIC has not stopped the development and production of more advanced chips such as 7 nm, Chinese companies know that the United States is hoping to lock China's technology below the 14 nm process, in order to prevent the phenomenon of stuck neck, Chinese companies will continue to taoguang Yanghui, even if they cannot make a profit, they will not stop research and development. In the future, chips below 14 nm are the development trend of the market, and Chinese companies must not be satisfied with the self-sufficiency of the current 28 nm chips.
The various restrictive policies introduced by the United States, including restricting Japan, the Netherlands and other countries from providing lithography machines to China, the evil idea of locking China's scientific and technological development has not stopped, what do you think about the future development of Chinese chip companies? Welcome to discuss.
