Chapter 400

"Mr. Wang, Moore's law is an iron law in the development of chips. As long as we have enough research and development ability, we will continue to move forward along this law." Qin Guan said: "it was just my negligence, but I think it should not be particularly difficult for us to realize the 1 micron process?"

Qin Guan mentioned Moore's law, which was deduced by the semiconductor engineers of Eagle country in 65. It is very simple, but it is widely spread. In short, with the development of time, the number of transistors integrated on the chip will be more and more, and the price will be cheaper and cheaper.

This law is established in the western world, but not necessarily in the Han country, because the industrial foundation of the Han country is weak and there are not enough engineers.

"You're right," said Wang. "Do you know the manufacturing process of our chips? Do you know we need to use lithography? This kind of equipment, our current highest level, can only reach 10 microns."

10 microns, which is already at the highest level of our own side, is far from foreign countries. However, Mr. Wang has no way. He studies chips, not lithography machines.

"I can transform the lithography machine to achieve an accuracy of 1 micron," Qin Guan said. "Although you certainly don't believe it now, I think you can let me try."

Is this man really capable? Wang Lao is curious in his heart. If this person is nonsense, Lao Zhu won't be so stupid, right? Bring such people here. If what the other party says is true, I always feel I don't believe it.

This has exceeded his expectations.

"If there are old equipment in 1109 factory, you can try it." Zhu Lao said at this time.

Factory 1109 was established in the hands of Mr. Wang, near the semiconductor research institute. At the same time, after the completion of the research and development of the key projects at hand, Mr. Zhu once again became the factory director of factory 1109, responsible for transforming the design into products and dealing with the production line all day.

After hearing Zhu's words, Wang thought, "there is a slicer that can't be used. If you really have the ability, repair the slicer for me first."

Mr. Wang won't waste time. After saying this at the door, he went back and studied the chip design!

Chinese Academy of Sciences, cow!

Old song and old Tu didn't catch up at all. They knew that old Wang was too busy. In fact, they had a lot of things on hand, but they knew that Qin Guan was better and it would be good to follow Qin Guan. However, old Wang didn't know.

In Wang Lao's eyes, Qin Guan now seems to be a guy who can only talk big.

"Qin Guan, don't be angry. Lao Wang is so angry. He is also busy." Zhu said: "he has undertaken national key scientific research projects. He really has too much to do."

"It's all right." Qin Guan said, "Zhu Lao, take me to 1109 factory. Didn't he say there was a slicer? I fixed it for him."

Now, Mr. Wang thinks that Qin Guan is a liar. When the slicer is repaired, Mr. Wang will definitely come to him. Of course, he doesn't bear grudges. He can just talk to him about the chip development in China!

Slicer? I saw this thing when I was wandering in the machine tool cemetery. I'll wait for myself to show my skills in a while.

"Come on, let's go to plant 1109." Qin Guan said. Anyway, there was no meeting, so he strolled around here first.

Qin Guan also knows the slicer. Well, have you ever eaten instant boiled mutton? When you rinse mutton, you eat mutton slices, which are cut by a slicer. Cut large pieces of meat into pieces.

This is a similar step in chip manufacturing.

The original source of chips is sand. Yes, very cheap sand. Its scientific name is silica. Silicon is the most important semiconductor material and one of the most suitable materials for manufacturing modern large-scale integrated circuits.

It is not easy to turn silica into silicon, especially the purity required is quite high, which is the purification of silicon.

In this process, the raw material silicon will be melted and put into a huge quartz furnace. At this time, a seed crystal is put into the furnace so that the silicon crystal can grow around the seed crystal until a nearly perfect monocrystalline silicon is formed.

Finally, the silicon raw material is taken out by rotating and stretching from the high-temperature container, and a cylindrical silicon ingot is produced.

Generally, the diameter of silicon ingot is 200 mm.

The silicon ingot, like the steel ingot, is the initial manufacturing material. The next step is to cut the silicon ingot into flakes, called wafers. This wafer is really used in chip manufacturing.

At the same time, the thinner the slice, the less material, and naturally more chips can be produced. At the same time, the slice should be processed by mirror finishing to ensure that the surface is absolutely smooth, and then check whether there is distortion or other problems.

Therefore, slicer is also an important link in chip manufacturing, which is much more difficult than cutting mutton slices.

Compared with the treatment encountered in the Chinese Academy of Sciences, it was a big difference. When they came to plant 1109, they were immediately warmly welcomed by director Ma of the chief engineer's office of the plant.

"We are very welcome to hear that you are coming. Now, please change your clothes and go to the factory after passing through the filter room." director Ma is very enthusiastic.

This is a high-tech factory. The factory must be kept absolutely clean. Several people have to change into full-body overalls, and even their heads are wrapped tightly. Then, after being sucked in a vacuum suction room for a few minutes, they enter the factory.

"We now mainly produce integrated circuits. The chips used in our 150 computers are produced in our factory." director Ma also changed into the same clothes and introduced them to several people as he walked.

Domestic computers can also be produced, but compared with foreign ones, they will fall many times behind. Several people present felt that the project in hand was in urgent need of advanced domestic chips.

"The one in front is the slicer that we have repaired many times and can't repair," director Ma said.

Director Ma is certainly happy to hear that someone has come to repair the slicer. They have repaired it many times, but they can't repair it well. Now, there is only one slicer in the factory. If that one breaks down again, the factory will be paralyzed.

But these people don't look like them.

Under the external blockade, the state of Han can only rely on its own strength. The slicer in front of us is made by the state of Han itself.

"Our slicer can cut silicon ingots into 3mm thin slices," director Ma said. "The cost of this thin slice is quite high."

3mm? Qin Guan shook his head: "well, you can visit other places first. I need to be quiet and see how to repair it."
