Why didn't China develop its own chips? Which foreign countries have independently developed chips?

There are more than a dozen countries and regions that can manufacture chips, but the only countries that can design and manufacture high-end chips are probably the United States, the Netherlands and Japan. Whether etching machine smaller than 14 nm can be independently manufactured is a measure. China, too, has always been a domestic chip for military and aerospace. Japan, Korea and Britain have them. Chips are not patented in the United States, and other countries just take shortcuts to buy chips to reduce R&D investment.

Many countries have their own chips, only the powerful functions of chips and the integrity of chip industry, as well as their own independent development capabilities. At present, the problems to be solved by China chips are industrial integrity, development capability and independent intellectual property rights.

Lithography is the link between manufacturing and design. Many of these processes are carried out in independent factories, and the equipment used also needs to be manufactured by special equipment factories; The materials used include hundreds of special gases, liquids and targets, all of which require special chemical industry. In addition, the production of integrated circuits is carried out in a clean room, so exhaust and air purification systems are needed.

The key point is that China people are the best among those who have created the existing facts and status quo. Everyone says how difficult it is to make a chip, but the top chip is made by TSMC, of course, for others, which makes the internationally leading chip design technology owned by domestic and foreign companies including Huawei become high-end chips.

China is the only country in the world that can manufacture the world's top high-end chips. In chip design, Huawei Hisilicon leads the world. In the field of chip manufacturing, companies such as TSMC and SMIC in China have the highest chip manufacturing capability in the world, especially TSMC. Because the technology that the whole chip industry chain depends on, especially the top technology, basically comes from the United States, we have the most advanced chip semiconductor industry chain in the world. However, in the chip semiconductor industry, it will still be subject to the United States, so that companies in their own country cannot provide chip manufacturing OEM production for enterprises in their own country because of the restrictions of American laws and regulations.
