China's mature chip technology development deters the United States
Some time ago, foreign media reported that the United States and Europe are discussing a new strategy to prevent Chinese mainland from expanding to a mature process.
In the past, the United States was not limited to advanced technology, why is it now eyeing mature technology?The reason is that Chinese mainland is accelerating the production of mature process semiconductors, and the mature process capacity has ranked second in the world.
And China is expected to continue to develop, and mature technology is expected to become the world's first, so the United States is again"Beat the grass and scare the snake"Finish.
At present, the mature process defined by the industry refers to 28nm, as well as the 28nm chip process. Don't underestimate the 28nm and above process, in terms of quantity, it accounts for about 75% of all chips.
In other words, three-quarters of the world's chips have mature manufacturing processes. Nowadays, except for the performance requirements of some chips, such as CPU, GPU, AI, SOC, etc., which require advanced processes, the vast majority of other chips use mature processes.
85% of the world's chips are designed in the United States, but only 10% of the chips are manufactured in the United States, and the other 90% of chips are manufactured in Taiwan, Chinese mainland, South Korea and other places, and the United States accounts for about 50% of the global chip market.
It can be seen that there is a great demand for advanced processes in the United States, and there is also a great demand for mature wafer processes.
At present, China is limited by advanced technology, and vigorously develops mature technology, of course, let the sufferer"Paranoia"The United States is worried, for fear that its own mature process will be stuck by Chinese mainland in the future, so there is news of limiting the mature process.
Of course, some people say that the United States can not limit the mature process, because most of the domestic ** chains have reached 28nm and 14nm, and once suppressed, it will quickly lead to the national production of the 28nm process.
For the United States, the gains outweigh the losses, because if 28nm is not restricted, the localization process is not so fast, once restricted, domestic substitution will be completed quickly, and it will eventually be affected by these equipment manufacturers in the United States.
Of course, for the time being, restricting such a mature process as 28nm is just a statement, but it also reflects from the side that the United States has been frightened by the development speed of China's chip industry, and is trying to delay or block the development of China's chip industry, and we can't have illusions about the United States, we can only rely on ourselves and take all the core technologies in our own hands, and no one is afraid.
