People don''t intend to sell it to you at all. They can''t buy core technology. They can only rely on their own research!

    Western countries have signed a "Walson agreement", and lithography machines are not allowed to be sold to our country.

    With the help of the ball, Zhang Ziang is making a lithography machine step by step.

    "Little ball, check the precision of the lithography machine I made." the little ball wiped the sweat on his face and said.

    He has been in the Research Institute for more than a month. He has eaten the theoretical knowledge of the lithography machine for a long time. Now he is turning the theory into practice.

    "Master, the precision of the lithography machine you have developed has reached 50 nanometers," said the ball.

    Zhang Ziang shook his head after hearing this: "still not, little ball, help me check what''s wrong."

    "There are some defects in the alignment system of your lithography machine, so that the accuracy has reached 50 nm." the small ball pointed out the problem to Zhang Ziang straightforwardly.

    "I see." Zhang Ziang revised it again.

    Zhang Ziang''s factory is constantly bringing him wealth, but it is impossible to save money. Only by spending this money can it play its due value!

    Now Zhang Ziang has been building a chip production factory. It can be said that the factory built this time is the largest factory invested by Zhang Ziang. After all, the production of chips has very high environmental requirements and has great restrictions on the indoor temperature and humidity of the factory.

    Chips produced at different temperatures are different.

    And must achieve dust-free production!

    In order to build the technology ball chip factory, Zhang Ziang has invested tens of billions. All this is worth it. You know, the chip market is very broad. The output value of chips has reached an amazing 2 billion worldwide, and is still rising. With the big engine of intelligent robot, it is bound to rise greatly.

    In the future, robots may develop into adult hands. Like mobile phones, robots may replace mobile phones at that time!

    There are two beautiful and dazzling pearls on the industrial crown. The first is the engine of the space shuttle and the other is the lithography machine.

    For the engine, Zhang Ziang has developed the motor, which will be used in the space shuttle in the future. The most critical place has been developed. Now he is working overtime to build his own space shuttle.

    Zhang Ziang is confident that it will be built in three years!

    Lithography machine... Under the guidance of the ball, the precision of the lithography machine is getting higher and higher

    "22 nm..."

    "10 nm..."

    "5 nm..."

    "1 nm..."

    "Master, Congratulations, the lithography machine you have made is already the most advanced lithography machine of water polo, that is, those so-called developed countries, their lithography machines are not as precise as yours." Xiaoqiu said happily.

    "No... that''s not enough!" Zhang Ziang said stubbornly. Only 1 nm is not Zhang Ziang''s goal.

    Keep studying!

    "0.5 nm!"

    "0.3 nm!"

    "0, 05 nm!"

    ……

    "0.0001 nm!"

    Three months later, Zhang Ziang''s hair can be tied and braided, his beard is sloppy, and his eyes are full of blood, but his eyes are brighter and brighter. He excitedly looked at the lithography machine in front of him and clapped his hands: "so far, a lithography machine with a precision of 0.0001 NM has been developed, just so..."

    "This time it''s not that they don''t sell it to us, it''s that we don''t sell it to them!" Zhang Ziang said. In the past, if we bought a foreign lithography machine, we didn''t just say all the good words, but volunteered to take on the role of a little Aries and was slaughtered by the other party.

    Even if it is finally sold to us, it is also a lithography machine that has been eliminated for ten years!

    "Xiaoyu, how is our chip factory now?" Zhang Ziang was concerned about the construction of his own factory for the first time. After he beat the money, he immediately invested in research and had no time to ask.

    Now we have developed a lithography machine to our satisfaction, which naturally reminds us of our own factory.

    "Boss, after you smashed a lot of money in, our first chip assembly line has started production. In the next five months, our other assembly lines will start production one after another."

    Zhang Ziang nodded after listening: "our company has developed a high-precision lithography machine. Please call someone to pull it."

    "Really, boss, you are so strong," Zhang Xiaoyu screamed.

    She knows that it is said that the company has developed it. In fact, it is developed by Zhang Ziang!

    Zhang Xiaoyu also has a lot of knowledge about the lithography machine. He knows that the most important thing in manufacturing chips is the lithography machine. Watching the chip factory change day by day and big in three days, he is not only pleased, but also worried about Zhang Ziang.

    What if... What if the factory is built and there is no advanced lithography machine to produce chips, or the chips produced are not qualified at all?

    Now the leader Zhang Ziang has developed a high-precision lithography machine, and a big stone in her heart finally fell. Although she doesn''t know how high the high-precision is, she believes that Zhang Ziang''s products must be high-quality products!

    Soon, people from the science and technology ball factory came to receive the lithography machine. Now there is only one, but Zhang Ziang is going to work overtime to manufacture ten more.

    I believe these eleven can meet the needs of our factory for the time being.

    "Master, what about these lithography machines?" said the ball, which were the failed products.

    "It''s all ruined. These are of no value to me, but they can''t fall into the hands of others!" Zhang Ziang said.

    "Yes, master."

    Nano robots were released by small balls and drilled into the bodies of these lithography machines. Before ten seconds, these lithography machines were decomposed into particles, like sand.

    Seeing this scene, Zhang Ziang felt a little scary.

    ……

    In the technology ball chip factory, the lithography machine has been in place and began to be busy, constantly transforming quartz sand into monocrystalline silicon.

    Then the monocrystalline silicon is processed into silicon wafer, and then the wafer is coated with photoresist film in order to increase the temperature resistance and oxidation resistance of the wafer.

    Then wafer lithography development, ion implantation, wafer testing, packaging

    Each step works in a dust-free environment. A program error can affect the quality of the chip and even scrap it!

    Dozens of staff in white coats are constantly recording data and sampling the quality of chips from time to time to avoid batch problems.

    These staff members were excited: "I''ve never seen such a high-precision chip. It''s incredible!"
