Being stuck in China's neck, the United States also has today, but in desperation, it will treasure from waste products

　　The United States has been using its chip technology with monopoly technology to block the neck of China chip, constantly increasing chip restrictions, and even wooing Japan and the Netherlands to restrict the sale of chip equipment to China. Recently, however, foreign media reported that the United States was blocked by China this time, and in desperation, it will import waste products from Canada to recycle rare metals.

　　As the United States has repeatedly taken measures against China's chips, China has earlier taken control measures against the export of rare metals such as gallium and germanium, which have an advantage in China, resulting in a heavy blow to the American chip industry.

　　Gallium and germanium have an important influence on American chip, aerospace and other industries. Nowadays, silicon-based chips are approaching the limit, and the global chip industry is looking for new chip materials. Gallium compounds are considered as important fourth-generation chip materials and have been widely used. Gallium compounds such as gallium nitride have been widely used in automobile chip industry. Germanium is widely used in aerospace and optical fiber industries.

　　China has nearly 70% of gallium reserves and more than 40% of germanium reserves. China is the world's largest producer of gallium and germanium. Although the United States also has rich germanium deposits, it is difficult to purify germanium in the United States because it is associated with zinc and lead, which leads to great production pollution and high cost. China's germanium mainly comes from brown coal mines. Because China uses a lot of coal, the production cost of germanium is lower and the technology is more mature, so China is the world's largest exporter of gallium and germanium.

　　With China's measures to export gallium and germanium, the global supply of gallium and germanium is facing a shortage, while the United States, as the world's largest scientific and technological power, has a great demand for these rare metals. Now, faced with the shortage, it has to recycle these rare metals from its own waste products, but it is still far from meeting the demand, so there is a plan to import waste products from Canada to recycle these rare metals to ensure the demand of the American science and technology industry.

　　The United States is the world's largest exporter of chips, accounting for nearly 50% of the global chip market. However, the share of the United States in the global chip market is steadily declining. In the early years, the share of the United States in the global chip market was as high as 70%, and China's stranglehold on rare metals will probably lead to a further decline in the influence of the United States in the chip industry.

　　China and the United States have launched a fierce competition in new energy vehicles. Gallium compounds, such as gallium nitride, have been widely used in the automobile chip industry, and automobile chips are now in the ascendant, which has gradually become an important classification of the chip industry. After all, a car may use as many as 1,000 chips, while mobile phone chips only have about 100 chips. China will further consolidate its competitive advantage by relying on the advantages of gallium.

　　Automotive chips are less dependent on the chip manufacturing process. At present, many automotive chips still adopt mature processes, such as BCD process developed by chip manufacturers in stmicroelectronics and China, 55nm BCD process developed by chip manufacturers in China, and 90nm BCD process still used in stmicroelectronics. These processes, together with gallium compounds such as gallium nitride, can provide better performance.

　　Under such circumstances, it is not surprising why the United States is so nervous about the supply of rare metals such as gallium and germanium. These rare metals are very important for the United States to ensure the leading position in the chip, aerospace and other industries. In order to ensure the supply, it is necessary to quickly seek treasure from the waste products of its own and Canada.

　　Facts have proved that the cooperation between China and the United States is beneficial to both sides. However, the practice of the United States has not had much impact on China's chips. The data from March to June this year show that China's chip production has rebounded continuously. In contrast, the American chip industry has suffered huge losses, leading to the decline of Qualcomm and Intel, and it has to lay off a large number of employees. American chip companies even shouted that if they do not sell chips to China, American chips will have nowhere to sell, and the supply of rare metals in China is more likely to further weaken the competitive advantage of American chips. I hope that the United States will further weaken its chips.
