Semiconductors originated in the United States, but why did they not monopolize the market? Just loo

The semiconductor industry is mainly used in a variety of high-tech products, including computers, hard disks, optical drives, mobile phones and other products. The semiconductor industry can make the volume of products become smaller and smaller, the power consumption is lower and lower, but the service life is longer and longer. The emergence of smart phones represents a high degree of combination of material technology, semiconductor technology and electronic technology. Take Huawei's latest mate20 pro as an example. It has the most advanced semiconductor technology at present, with a processing chip of only 7 nanometers and a battery of 40 megapixels, three lenses and 4200 mah.



The entire mobile phone is only 8.6 millimeters thick, can last 30 hours of talk time, standby time up to 15 days, but Huawei's Kirin chip 980 is the best semiconductor technology, using a seven-nanometer process, integrated 6.9 billion transistors in a small chip. Not only that, in order to make more products demechanized, increase their intelligence, semiconductor is becoming more and more important, talking about the car, engine battery, controller and other parts, the use of semiconductor technology can make the size of the smaller and smaller, AI chip is gradually becoming important to the car, it can be seen that the chip industry is the top priority of all intelligent products.



Compare the semiconductor business in China and the US and you will find that China is not that far behind the US. Although the semiconductor industry originated in the United States, the advantage of the United States is not that great in many aspects. Let's take a look. First of all, the semiconductor industry is divided into several modules, which are materials, equipment, processing and manufacturing, chip design and other links, among which the manufacturing of chip material called silicon wafer, its purity needs to reach 99.9999999% (seven decimal points nine) to line, which Japan occupies 50% of the market, followed by China Taiwan, Germany and other countries, the United States has no advantage.



And then there's the equipment. The manufacturing of equipment is mainly divided into three steps: silicon wafer manufacturing, wafer manufacturing, packaging and testing, and wafer manufacturing is the most important. It takes more than 70% of the capital to invest in the construction of a wafer field, including the purchase and production of equipment, accounting for about 80%. In terms of its equipment, high-end lithography machines are monopolized by the Netherlands, and deposition equipment is sold first in the United States. The etching machine is at the leading level. Of the three kinds of equipment, America occupies only one. The etching machine can reach one in 20,000 precision, and will be manufactured by Huawei's 5 nanometer chip in the future.



Wafers are factories that produce chips. In China, Taiwan Semiconductor Manufacturing Co., LTD. (Taiwan Semiconductor Manufacturing Co., LTD.) is the leading company in technology and has successfully produced chips with a seven-nanometer process. Huawei's Kirin 980 is its proud product. The last chip design. In the computer chip design, the United States Intel and AMD is undoubtedly dominant, the most important or user habits and soft and hard together, it is difficult to break this monopoly.



But in the server, supercomputer, and smart phone this piece of domestic manufacturers are catching up, China's supercomputer and fully realized the ability of independent research and development of core products, Huawei also released the Taishan series of server chips. Ali, Gree, Foxconn, the three domestic giants have also entered the semiconductor industry. For example, Alibaba mainly develops AI chips, Gree also wants to invest in the chip field, and Foxconn plans to invest in a wafer factory in Zhuhai to transform into high-end chip manufacturing. The participation of these bigwigs also shows the booming development of domestic chip industry.
