Before the reform and opening-up, Nanjing Radio Institute was developing mask aligner, Dalian, Dalian, and there were also large aircraft. Dalian 523 Military Factory mainly produces nuclear storage batteries and civil nuclear power. Later, these projects were demolished one after another, resulting in today's passive situation, which is quite a pity. The research and development of some high-tech products can not be completed overnight, and it is really necessary to accumulate breakthroughs one by one, find problems and solve difficulties.
Not only mask aligner, but also many other cutting-edge equipment and technologies need us to overcome difficulties. China, a big country, has been bullied by foreign powers for one hundred years, and this account will be settled sooner or later. Britain, Japan and the United States also know in their hearts that we had the courage to compete with the established United States in North Korea when we were just founded, not to mention the rapid development momentum at present. There is no first in literature, and no second in martial arts. Of course, the United States will do everything possible to make things difficult for us. Only when we are knocked down will it feel at ease.
Speaking of the key difficulties in national development, it is terrible for other countries to make mask aligner not exist with the strength of the whole country. This is not a special weapon to destroy mankind. Only let other countries understand that any technical blockade of China is futile under the national efforts!
Professor Qian Xuesen also studied in the United States for many years and returned to China after many twists and turns. His technical expertise has not left the scientific and technological soil of the United States. At present, China should develop research chips in an all-round way and mobilize all favorable factors. Whether at home or abroad, we should integrate our enthusiasm and work towards a goal. I believe that China will eventually overcome the chip difficulties!
If China can make mask aligner simply and quickly through one country. 5 nm, 2 nm, will give people a particularly strong feeling, the rest of the world will be more afraid, and the external environment surrounding China will form faster, so we have to leave them time to get used to it, or boil frogs in warm water. Even if we do, it will give people a hard feeling and pay a huge price. No country wants the world to have such a powerful opponent.
Mask aligner consists of several systems, each of which is the top technology in the world. For example, the optical lens is made by Zeiss. As long as we concentrate our efforts, the camera will surpass Germany in three years, and the Nobel Prize winner will surpass Europe and America in five years. As long as China's technology is fully advanced within five years, European and American students will come to China instead of China students to study in Europe and America. On that day, the high-end mask aligner will be built!
Although it is a bit exaggerated to say that it can be built in minutes, it is obviously not a problem. High-end mask aligner, the global market demand is only $2 billion per year. If you can buy it and choose to build it yourself, the company in China must be crazy. Large-sized mid-range chips used in the fields of national defense and military have long existed in mask aligner and China. Everyone must understand this matter. Just like many parts that need to be imported at present, China does not manufacture these parts because of market considerations, not because technology cannot solve key problems.
Many technologies that China didn't master were not incapable, but out of interest. Take a ballpoint pen as an example. Many people say that ballpoint pens cannot be produced in such a big country. It's not that China can't do it. Japan has ready-made beads, and the price is not high. Buying them is the most affordable. If China does it himself, first of all, R&D is a cost. After production, because of the attached R&D cost, the sales price will definitely be higher than that of similar products in Japan, and there is no sales channel. Even domestic manufacturers will not use high-cost products. Without market competitiveness, they will not make money, so there will be no manufacturers to do it. But if the upstream pinch, don't buy it for us, it will take a short time to make a refill bead.
Mask aligners cannot be manufactured by many people. The lens technology it needs is too harsh, and the synthetic lens may not meet the requirements. Japan has the only giant natural lens in the world, which was found and bought from Africa. Uniqueness is irreplaceable, and many people can't show it. Japan's top mask aligners may be hidden from the public.
Mask aligner is a high-tech enterprise with many countries, and it took more than ten years to achieve today's achievements. There are countless patent applications in the middle. As we all know in mask aligner's manufacturing principle, it is very unlikely that you will make a leading mask aligner, because first you have to bypass their patented technology and then make light sources, optical lenses and precision machinery, which cannot be done in three, five or even ten years in a country.
