The richest man Yang Fei

Lithography machine, British name ask aigner, also known as: mask alignment exposure machine, exposure system, lithography system, etc., is the core equipment for manufacturing chips.

It uses a technology similar to photoprinting to print the fine patterns on the mask onto the silicon wafer through light exposure.

The exposure machine is the core equipment for the production of large-scale integrated circuits. Manufacturing and maintenance require a high degree of optical and electronic industry foundation, which is mastered by only a few manufacturers in the world.Therefore, the exposure machine is expensive, usually in the range of 3 million to 5 million US dollars.

High-end projection lithography machines can be divided into two types: stepping projection and scanning projection lithography machines. The resolution is usually between seven nanometers and several microns. High-end lithography machines are known as the most sophisticated instruments in the world. There are 12 in the world. A lithography machine worth a billion dollars.

High-end lithography machines can be called the flowers of the modern optical industry, and their manufacture is so difficult that only a few companies in the world can manufacture them.

Foreign brands are mainly based on Asmer in the Netherlands, which is company a. Their lenses come from Germany, as well as Nikon.

And the only one who can have the last laugh is A in the Netherlands.

Domestic mobile phone manufacturers, at best, do some assembly work.

Of course, the assembly work is also very promising, and it also has a lot of technical work. If it is done well, it can still make the enterprise bigger and stronger.

However, the chips are in the hands of others. Once others cut off the supply, you will have no chips to use, and you will not be able to make mobile phones. At that time, the higher you rush, the worse you will fall.

What Yang Fei wants to do is not a short-lived PHS, but a lithography machine for the future!

As for how to do it, Yang Fei is already planning it!

Chapter 2286 Optoelectronics Company, born in 2002

In fact, my country's lithography machine technology has not always lagged behind others, and there have been glorious moments.

Before the 80s, although our country was poor and white, it was never willing to lag behind in the overtaking of technology.

In the past, we also built a world-leading lithography machine.

However, after the reform and opening up, too many things poured into the country, and hard-working people suddenly discovered that many things don't need to be invested too much in research and development, they just need to be brought.

The use of doctrine has allowed our country's economy to soar rapidly in a short period of time.

As a result, the lithography machine, a long-standing and difficult project, was stagnated for decades.

Everything pays attention to an "infrastructure".

How important is infrastructure

Just look at the United States during World War II.

After the outbreak of World War II, the United States quickly shifted its national industrial capacity to weapons manufacturing. From 1941 to 1943, the production of US tanks soared from 4052 to 29497, a fivefold increase.

During World War II, the United States produced 262524 aircraft, and the overall quality was n levels higher than that of Japan, and the number exceeded the sum of Japan and Germany.

These aircraft and tanks are not used by the United States itself, but are used by the entire anti-front in Britain, France, the North African battlefield, and our battlefield. There is more than enough.

Japan surrendered. At the end of World War II, the United States suddenly didn’t need to build aircraft and tanks. The workers who were working hard were quite disappointed: the factory has not had such a good profit in the past 200 years since the founding of the People’s Republic of China.

I am afraid that only my country's current mask factories can experience the feeling of the American arsenal.

Why America Can Become So Powerful Overnight

Because their infrastructure is already leading the world.

Before World War II, there were more cars on one street in Detroit than in all of Japan

Therefore, once they enter wartime mobilization, they quickly switch their productivity to weapon manufacturing.

Our country is also vigorously developing infrastructure, and the results are remarkable.

However, after entering the 90s of the last century, a "parallel world" suddenly appeared in our lives, that is, computer networks.

This parallel world also needs infrastructure.

However, my country's infrastructure in this area is obviously lagging behind Western developed countries.

When we understand it, our level of lithography machines has fallen far behind the West.

Some people describe the lithography machine like this: This is a product that integrates top technologies in the fields of mathematics, optics, fluid mechanics, polymer physics and chemistry, surface physics and chemistry, precision instruments, machinery, automation, software, and image recognition.

The working principle is to use "ultraviolet light" as a knife to carve the wafer, so that the circuit on the chip becomes the pattern people want.

my country's lithography machine industry lags behind the West by 15 years. In a word, this year is 2002. If the West cuts off the supply of cores to a Chinese company after 15 years, the level of chips produced by my country will be equivalent to those produced by the West in 2002. chip.

In terms of data, when the West can manufacture 7n process chips, our country can only manufacture 90n process chips.

As we said before, there are three major lithography machine manufacturers in the world. Later, because R&D was too expensive, even Canon and Nikon in the island country withdrew from the group chat and no longer developed a new generation of lithography machines.

my country is not without chip companies, nor is it without lithography machine manufacturers.

What Yang Fei has to do now is to set up a lithography machine research and development center in Shanghai.

In 2002, because of Yang Fei, he was destined to be extraordinary.

Domestic lithography machine technology, also because of the appearance of Yang Fei, will develop more steadily and faster than before.

Just before Yang Fei was about to go to the United States to "ring the bell", he suddenly left Shanghai and went to Beijing to meet an important leader Li Yi.

Li Yi is now in charge of the electronics industry.

Yang Fei talked eloquently, encouraging his three-inch tongue, and told Li Yi about the past and present of the lithography machine, in order to create the infrastructure that our country needs in the "parallel world of computer networks".

Li Yi in front of him looks so young. Although his face looks so resolute and his eyes are so firm, he still can't hide his youthful aura.

Yang Fei thinks that the concepts he mentioned are very advanced.

Perhaps, nine out of ten people cannot understand his point of view.

Fortunately, Li Yi is one-tenth of the other.

Yang Fei didn't even need to say more, just raised his head, and Li Yi understood what he was going to do.

Li Yi has a clear vision of the future world

This made Yang Fei feel like he had found a confidant.

Li Yi agreed to support Yang Fei in making a lithography machine.

This support is not just in words, but in action.

Not only policy support, but also more practical actions.

Li Yi matched up and persuaded Longteng Fund and Sihai Group to take a stake in Yang Fei's new company

Sihai Group, like Longteng Fund, is a huge domestic heavyweight economy.
