Learning is never-ending, what are the core technologies that China has yet to master

Our country's manufacturing industry has long been at the top of the world, but in terms of creation, our country is still relatively backward. Many of the world's top core technologies, our country has not mastered, to a large extent, making our country's development subject to foreign countries. The following are some of our country has not mastered the core technology, our country's development is a long way to go.

The development of science and technology can not be separated from the semiconductor, so a country's semiconductor processing technology advanced or not, can reflect the country's scientific and technological strength. Semiconductor processing design to a very large number of technologies and equipment, currently the most advanced technology in this piece of the United States and Japan, other countries are relatively backward, including China.

These years Huawei pressure, I believe we all know the photolithography of this thing, photolithography is mainly used for the chip carving circuit. Our country's chip technology has not been able to develop, to a large extent can be said to be stuck in the photolithography. The most advanced chips in the world are already as small as 5 nanometers, while our country can only produce 12 nanometers now, and the breakthrough of 7-nanometer technology will take several more years. For now, our country can only buy photolithography machines from the Netherlands.

Most machines have bearings, don't look down on the bearings of this small part, the bearings for a machine to play a very important role in the operation. Do not think that look at the simple bearings and not much technical content, in fact, now our country has not mastered the core technology of bearings, bearings of the core technology mastered in Germany and Japan.

Many important parts on the machine, the precision requirements are particularly high, such as aviation, ships. High-precision parts for the overall performance of the machine and the life cycle of the impact is very large, so it is very important to improve precision. The core technology of ultra-high-precision machine tools is not yet mastered by our country. Mastery of the core technology of ultra-high precision machine tools are mainly Germany, Switzerland, Japan.
