Chapter 577 (2/2)
”At the same time, I can give you a popular science here. Wafers are needed to produce chips.”
”The so-called wafer refers to the silicon wafer used to make silicon semiconductor circuits, and its raw material is silicon. High purity polycrystalline silicon is dissolved, mixed with silicon crystal seed, and then slowly pulled out to form cylindrical monocrystalline silicon. After grinding, polishing and slicing, the silicon crystal rod forms a silicon wafer, that is, a wafer. ”
”The main processing methods of wafers are wafer processing and batch processing, that is, processing wafers or multiple wafers at the same time. With the smaller and smaller feature size of semiconductor and the more advanced processing and measurement equipment, new data characteristics appear in wafer processing. At the same time, the reduction of feature size increases the impact of the number of particles in the air on the quality and reliability of wafer processing. With the improvement of cleanliness, the number of particles also presents new data characteristics. ”
”Chip processing not only needs to be carried out in a very clean and precise environment, but also has very high requirements for raw materials. Silicon is common in nature; Silicon can be extracted from sand and stone. The main reason why we choose to build a factory in Israel is that the silicon content in the sand is about two thousandths more than that in other regions. ”
”You may feel that two thousandths is nothing. That's a big mistake. As the content of silicon in raw materials increases by two thousandths, chip factories can produce at least 50000 more wafers under the same conditions every year. ”
”According to the calculation of $300 per wafer, you can earn an additional $5 million a year. It doesn't look like a lot, but raw materials with high silicon content can improve the performance and purity of wafers. Under the same conditions, the performance of chips produced in Israel will be better. ”
”To this end, we also specially purchased a batch of raw materials and tested them in Xiangjiang. It can be said that the test results are very satisfactory.”
”Therefore, there is no interest binding problem in building a factory in Israel. It is entirely because we can make more money.”
”As for you, it is also because of the geographical location that you said the plant was built in Saudi Arabia. The sea based version of ground effect aircraft has been produced in Xiangjiang. The terrain of the subgrade version is mainly used in desert areas. Saudi Arabia has a vast desert, which is very suitable for experimental sites. ”
”In addition, Saudi Arabia is also the country that purchases the most ground effect aircraft. Meeting the needs of customers has always been what heiyun is constantly doing. As for the steel plant, it is entirely for the supporting use of ground effect aircraft. This large object requires a lot of metal materials, and local production will be more economical, which can increase the company's profits. ”
”So the interest exchange you said is not tenable at all. There is an essential difference between industry and finance. Industry needs to consider many aspects. We should comprehensively consider various factors, and then analyze where it is more appropriate to establish a factory. ”
Hearing baozixuan say that the sand in Israel is good, many people feel that this is nonsense. However, seeing that Bao Shoufu is serious, is it true.
His words excited the Jews. It turned out that God was not thin on them. Although there is no Arab oil resources nearby, it is also good to have better sand and stone than other parts of the world.
Baozixuan of heiyun group belongs to the world's top authoritative expert in this regard. Many people still believe his words.
Not only the Jewish journalists were very excited, but Shamir sitting on the podium was even more happy and had to jump up. Israel has such good resources that it doesn't know. No wonder baozixuan can become a super rich at a young age. Many people can't match this ability to control business alone.
When you go back, you must check carefully, but you can't let mercenaries steal precious sand and stones belonging to Israel. Shamir's worry is still very reasonable. Many people really go to Israel to study sand and stone. The direct result is that the price of sand and stone in Israel will always be higher than that in other places in the next few years.
What's more surprising to the Jews is that many chip factories are going to visit Israel. They all feel that this kind of good thing can't be occupied by baozixuan alone.
In Jewish Terms, the efforts of Israel Merchants Group in 30 years can not catch up with baozixuan. A word is more effective, which may be the star effect. At least in the field of science and technology, baozixuan is a star and a superstar.
Saudi Arabia itself is a big purchaser of ground effect aircraft, and it is understandable to build factories there. Is it inappropriate to build a factory in a country that has not bought anything.
