The mask aligner is a machine. You can disassemble the machine until the original parts are independent, especially the key parts. You will find that to make this part, you need to list many technologies and equipment. Just like a tree with countless branches and leaves, there is no need to entangle the context. Perfecting these branches and leaves alone can kill ten thousand people!
Now SMIC can achieve 28 nm, which is also the mainstream machine. Orders have been queued for several years, and now the 14nm machine has been successfully rolled off the assembly line. Because the yield is too low, it is being debugged now and will definitely be mass-produced next year. However, this is not the most advanced lithography technology in China. Tsinghua University's duplex 4 nm mask aligner has completed the prototype manufacturing and is now in the debugging stage. I believe we will hear good news soon. We also participated in the development of the 3-nanometer process, and we are the main funder. Look at these. Who can say that our future is not bright?
China goes it alone in manufacturing in mask aligner, while the Netherlands, ASML and mask aligner have concentrated the technical essence of many developed countries. The Netherlands is not a country. Therefore, China can independently produce 90 nm mask aligner. I think China is great. Come on, China!
As a China person, it's really not easy. Therefore, all high technologies must be developed by ourselves, and the core part that China needs will be restricted by western countries. There is no alternative but to rely on the people of China themselves. Although the situation is so bad, I am glad that I am from China, and I am proud that in a few years, there will be only China and foreign countries left in the world. It shouldn't be long. Come on, come on, China.
At present, there are five domestic enterprises that can produce mask aligner. The most advanced one is Shanghai Microelectronics Equipment Co., Ltd. The chip technology of mass production in mask aligner is 90 nm, and now it is moving towards 65 nm, while the most advanced one abroad is 5 nm, which is moving towards 3 nm, with a difference of 9 steps. According to the gap of 4-5 years in each step, it will take another 40 years to catch up.
It is suggested that China should stick to economic development and invest mainly in infrastructure, education and high technology. We should have what others have, be more advanced than others, and really have what others don't have. It is best to ignore or turn a blind eye to other countries' affairs without causing great losses to our country. Under the condition of ensuring national security, we must never engage in an arms race, let alone resist US aggression and aid Vietnam. As long as the people endure for 25 years and develop the economy calmly, and the national output value of our country reaches $50 trillion per year, exceeding the total output value of the United States and Europe, then our country is a mobile phone, and how our country regulates the world is up to us.
There is a specialization in the industry. We started our own research many years ago and spent a lot of money and energy, but in many aspects, it seems that we can't do this well from basic education and so on. Like football, western high-tech technicians are calm and delicate, and their overall quality is also very good. Many people think while listening to classical music, and their thinking modes are different. This style of play in the United States is wrong. Now it's global cooperation, going against the sky, forcing an enterprise in China, a country in China, to realize everything including high-precision measurement, high-precision control and various high-tech fields from the most basic materials and parts. An enterprise and a country can compete with the whole world, and a superpower can't do it itself. How can we do it? This is naked bullying. China should fight back forcefully at all costs.
The genius of mask aligner lies in the ingenuity of this enterprise. After several generations of efforts and continuous technical precipitation, today's core technology has been formed step by step, which can not be achieved overnight, let alone at a cost. This is a basic logic. If we can throw money at it, can we throw a space elevator? Our enterprise for hundreds of years is almost blank. What is the average life span of an enterprise?
I haven't seen the principle in mask aligner, but the difficulty is how to make such fine light. Please kneel down to Japan with photosensitive glue. Such fine light can only be focused, and considering the problem of stepping, there must be a big optical lens, a light source and a stepping motor, which can beg for beauty, Japan and Germany. If you have a motor, you must have a driver and a guide rail. Can you do it? If you can't do it, you can hang yourself. I can't save China. Spending money can produce high-end mask aligner. That was not the case. High-end mask aligner, high-end aero-engine and high-end ultra-precision CNC machine tools involve many fields such as design, materials, processing, technology, testing and standards. All these depend on talents, research, technology accumulation, time investment and of course a lot of money.
Someone said it well: money is not everything, but you can't do anything without money? But what others say is more reasonable: Any problem that money can solve is not a problem? In the field of chips, money alone may not solve the problem. Why else should we spend so much money on it? Why does Huawei prefer to be fined so much money and want American chips instead of investing money in its own manufacturing? The key is that money can't be earned! In some areas, you can't imitate reversing, overtake in corners, or shout? Slogan? Shout it out and catch up is the right way.
Regardless of the cost, it is only a matter of time before China comes up with high-end mask aligner. If high-end chips are also produced, their own lithography opportunities will be used by their own chip manufacturers, and there is no need to enter the country again. Foreign chip manufacturers can't sell chips, so naturally they don't buy mask aligner, which drives Dutch mask aligner manufacturers to lose money or even close down. China is a real giant in the world. It is natural to make money. Only China can do this in the world.
