"Then the most critical CPU chip on the computer is really made of sand?" Huang Tian asked curiously.

Although Zhang Bixuan knew that the provincial party secretary had asked this question clearly, did not all send them a more detailed scientific information before coming? The information at least introduced some semiconductor common sense in plain language. The question of the chip raw materials is as novice as sand, and in fact even middle school students know how to answer it.

But Zhang Bixuan still smiled and said, "Yes! Not only is this CPU raw material sand, but almost all semiconductor chips are sand. For example, the memory on the computer, the chips on the hard disk motherboard, etc. are all made of this valuable sand. After this trouble, the value of this inconspicuous sand has increased by many times! Originally, the sand used for construction materials on construction sites was only a few dozen yuan per ton of sand. Now, this gram of high-purity silicon single crystal is more valuable than a truck of sand! Chief Designer Deng said it well, technology is the primary productivity!"

Since ancient times, human beings have always had the desire to turn into gold. Chip manufacturing is to turn sand over and over, and the final product price is no less than gold. It can be seen that human desire is the greatest driving force for social progress, and the desire for knowledge is also a kind of desire!

When entering the factory for a visit, everyone changed into special clothes before they could enter.

The production of chips is carried out in the factory's clean room. You should know that a chip the size of rice is integrated with thousands of transistors, and a dust that can be seen from the naked eye falls towards the chip. It is definitely a disaster.

The amount of dust generated in a clean room can be considered for local exhaust air removal and does not flow into the room; the dust generated in products, materials, etc. during transportation is generally very small and negligible compared with the amount of dust generated in the human body; since the application of half-wall of metal comes from the building surface, generally accounting for less than 10%, and the dust generated mainly comes from people, accounting for about 90%. In terms of the amount of dust generated in people, due to the improvement of clothing materials and styles, the absolute amount of dust generated is also constantly reduced.

If you wear ordinary clothes directly, it will definitely become a source of pollution and affect the pass rate of clean room products. Therefore, everyone changed their body protective clothing and wore masks before going in to visit.

Along the way, Zhang Bixuan witnessed the staff busy on various production lines calmly. In addition to the staff who accompanied him and others, most of them focused on their energy in their work. There were only a small number of workshops in chip factories started construction. The reason was that there were only technical personnel from the Chinese Academy of Sciences and personnel sent by Intel. There were not many qualified technical workers in chip factories in China. There were technical workers in computing, and most of them were in some state-owned enterprises. These people were specially trained by the state. If they were less, they would be useless. If they were more, the country would definitely disagree.

At this time, Intel CEO Grove felt a little fooled. He sold Zhang Bixuan equipment not just to rely on these equipment that were about to be eliminated, but to build a factory in China to help him produce 286 chips and 386 chips that will be eliminated soon. However, Zhang Bixuan was sorry to tell them that chip production is high-tech, not anything that anyone can do. So we don’t have technical workers, and there is no technical workers. Intel has to send someone to help me train. It takes at least half a year to train technical workers. If they cannot produce within half a year, it will affect the production of Intel’s 286 chips and 386 chips.

What an international joke? Although Intel has shifted its focus to producing and improving 486cpu chips, it does not mean that they are going to give up the market of 286 chips and 386 chips. The 486 chips can enter the mid-range and high-end markets, and the output of 286 chips and 386 chips is related to whether Intel can maintain its low-end market share.

What should I do? It's very simple. Glov sent 1,000 employees to assist in the production of Longteng CPU factory while helping Longteng Technology train technical workers.

The manufacturing process of chips can be roughly divided into several steps such as wafer processing process, wafer needle testing process, construction process, and testing process. Among them, wafer processing process and wafer needle testing process are the front-section process, while the construction process and testing process are the back-section process.

Longteng Technology's CPU factory basically empties the production equipment of Intel's headquarters 386, and this also includes all equipment from purifying silicon in the sand to making crystal rods, producing wafers, wafer processing, and final packaging and testing. This is like the headquarters of a CPU chip company, not like a foundry factory.

Many people often hear about a few-inch wafer factory. If the diameter of the silicon wafer is larger, it means that the wafer factory has better technology. In addition, scaling technology can reduce the size of the transistor and wire. Both methods can produce more silicon grains on a wafer, improving quality and reducing costs. So this means that among 1-inch, 3-inch, and 6-inch wafers, 6-inch wafers have higher production capacity. Of course, yield is a very important condition in the process of producing wafers.

Longteng Technology's wafer factory can produce 6-inch wafers, but it is not very technically backward, at least at the same level as Amd.

However, top semiconductor industry giants such as Intel and ibm are now able to produce 8-inch wafers.

After many experts led them to visit the factory and arrived at the factory where wafers were produced.

Secretary Huang Tian thought of something and slapped his head and said, "Hey? I found that this production chip is a bit like to toast! When I was making silicon ingots in front, I used a stick to bake the sand at high temperature. Now you look, the bread is baked and he will cut it into slices!"

After a little comparison, everyone present felt that it was really like that and suddenly laughed.

Making silicon ingots is to shape the collected high-purity silicon raw materials at high temperatures, and use rotary stretching to obtain cylindrical silicon ingots, which are shaped like bread and bake in the oven.

Zhang Bixuan smiled and said, "It's amazing! This baking is the essence of chip production. Secretary Huang is indeed extremely smart. He understands how to produce chips without any knowledge!"

Huang Tian laughed and said, "You are not good enough to flatter you. You just listen to it. I know nothing about technology and can't even type Wubi on the computer. I can still understand this high-tech with just one look? However, I am happy to see your Longteng's development. Look, what do foreigners think of our China? Foreigners always like to describe our country as being barbaric and backward. Once I went to South Korea for inspection, a Korean man actually took out a toothpaste and toothbrush and said to me, "This is called a toothbrush and that is called toothpaste. We Koreans all brush our teeth. After you come to Korea, you must also learn to brush your teeth. Since your government lets you
