But the developed mask aligner is definitely not the most advanced level in the world.
Although China's nuclear weapons, missiles and satellites are among the best in the world, there is still a technological gap with the United States, Russia and France. Just like the MIG -25 of the Soviet Union, it is equivalent to the SR-7 1 of the United States in performance, but there is a gap in technical level.
The result is that the line width is less than 10 nanometer in foreign countries, and it may be tens or hundreds of nanometers in China. In this way, the integration of the chip is greatly reduced. Other people's problems can be solved with one chip, while China needs several chips to solve them.
It has no influence on refrigerators, washing machines and rice cookers, but it has a great influence on mobile phones. With more chips, the power consumption will be high, the mobile phone will be thick and the battery will be large.
One of the reasons why Soviet planes and missiles are bigger than the United States is that mechanical equipment and electronic equipment are bigger and heavier than the United States.
The displacement of Soviet nuclear-powered guided missile cruisers exceeds 20,000 tons, while that of the United States is 1 10,000 tons. The Tu-160 bomber of the Soviet Union is larger than the B- 1 of the United States, and the Su -27 is larger than the F- 15 of the United States. China's J-20 is bigger than the American F-22.
No, but you can learn from it.
Have the same identity, be independent and go their own way; There are also differences. Chip and mask aligner are not made from scratch, they contain many patented technologies and use many special materials. This material also uses many patented technologies, and it is illegal to use these technologies without authorization. Therefore, it is difficult for China to make a set from scratch, and at the same time, it has made rapid progress from 7 nanometers now to 3 nanometers in 22 years. It is difficult to keep up with the pace of the world, and it needs many years of research and accumulation.
The technology is different, so we can't use the idea of developing missiles to delay the research and development of mobile phone chips and produce high-end mask aligner.
