In today's rapid development of the IT industry, the chip can be described as the brain of various data analysis, is the core! Now, for high-purity sputtering targets, the highest-end application area is the field of ultra-large-scale integrated circuit chip manufacturing, which is actually a field of semiconductor chips, and also occupies a large market share. Moreover, the market capacity of semiconductor chips in the future will be further enhanced with the continuous growth of semiconductor chip demand in the terminal consumer field such as automobiles.

China's in-vehicle chips can glimpse tungsten materials, more specifically, high-purity tungsten targets, which are tungsten targets with a purity of 99.999% (5N) or more. Tungsten targets are the key materials for the preparation of electronic films and are also targets for bombardment during sputtering. The tungsten targets can be classified into a pure tungsten targets, a tungsten alloy sputtering target, and a tungsten oxide sputtering target according to chemical composition. The production chain of high-purity tungsten targets mainly includes the purification of metal tungsten, the manufacture of high-purity tungsten targets, and the process of sputter coating. Among them, the manufacture of high-purity tungsten targets and sputter coating are important processes in the entire high-purity Tungsten targets production chain.

Since sputter coating is one of the key links in the entire tungsten targets production chain, it is necessary to know what sputtering technology is? Sputtering technology is one of the main techniques for preparing electronic thin film materials, and is one of physical vapor deposition techniques. Sputtering principle: high-pressure accelerated gaseous ions bombard the tungsten target, splashing the tungsten target atoms one by one, and depositing the splashed tungsten material into the target substrate as a snow film, that is, On the silicon chip. The high temperature and high vacuum environment inside the process chamber allows the tungsten atoms of these metals to form tungsten grains, which are then patterned and etched by lithography to form a layer of metal wires. The data transmission of the semiconductor chip for the vehicle is realized by these metal wires.

China has been the world's largest electronics manufacturing and importing country since the 1990s. However, at present, only Huawei, Ziguang and Cambrian can develop and produce some simple chips, and other important core chips are almost dependent on imports. Therefore, what is our conviction that we do not lack the "core" eye? Ever, "Made in China" is not an empty talk to the world! China's high-tech companies such as Ziguang, Huawei, ZTE and Alibaba are expected to realize the great ideal of replacing imported chips with domestic chips! Some readers may ask, can you have credentials?

First of all, talk about Huawei. Huawei is currently the world's largest communications R&D and manufacturing company, and invests tens of billions of dollars in research and development funds in core technology every year. Huawei is also a high-tech enterprise that is afraid of European and American countries. Its products are basically self-developed. Let's talk about Ziguang, Ziguang has developed very rapidly in the research and development of domestic chips in recent years, such as its successful development of the first 32-layer 3D NAND flash memory chips with complete intellectual property rights. Moreover, Ziguang invested 100 billion to establish a research and development base for the memory chip field. It is estimated that in the near future, domestic memory chips are expected to replace more than 90% of imported chips. Then ZTE Zhongxing. ZTE is the fourth-largest electronic communication company in the world and the second in China. It is said that a few months ago, the company’s top executives made a commitment to the people: ZTE will vigorously develop its own core chips, and today’s history will not repeat itself. The previous ZTE incident. Finally, it was Ma Yun’s Alibaba. Alibaba invested 100 billion yuan a year to create an Alidar House that has assembled a number of world-class chip research and development experts, only to create the core high-tech chips belonging to the Chinese themselves as soon as possible.

Semiconductors, going to the big, said that it is the cornerstone of the information industry. To be small, it is also the core of electronic products! Therefore, one of the only ways for the rise of China's science and technology is to develop semiconductor chips. As Premier Li Keqiang said at the 2015 Ministry of Industry and Information Technology Symposium - the traditional "MADE IN CHINA" we still have to do, but the core of "Made in China 2025" should be the main "Chinese equipment." The semiconductor chip is one of the "Chinese equipment" for China to take the road of science and technology.
