With its excellent mechanical, thermal, electrical, and other properties, tungsten has become an indispensable raw material for many modern industries. For example, the throat lining of large rockets needs to use tungsten-copper alloy, and many parts of small chips also need to use Tungsten and molybdenum products, such as diffusion barriers, bonding layers, electronic packaging materials, transistors, etc.
A chip is a semiconductor component produced by an integrated circuit after many complicated design processes. It is composed of a large number of transistors and is widely used in mobile phones, remote controls, cameras, alarms, and other equipment.
The tungsten target is the preferred material for the internal diffusion barrier and bonding layer of the chip due to its high melting point, strong high-temperature resistance, large electron emission coefficient, good chemical stability, and excellent heat dissipation performance. In addition, most mainstream packaging materials for integrated circuits use tungsten, tungsten copper, and gold. In addition to its excellent electrochemical performance and heat dissipation performance, tungsten copper alloy also has the characteristics of a thermal expansion coefficient matching that of silicon wafers and gallium arsenide, so it can make the performance of electronic packaging materials better in all aspects.
From January to March 2021, the output of my country's integrated circuits was about 82 billion, a year-on-year increase of 62.1%, while imported integrated circuits were 155.27 billion, a year-on-year increase of 33.1%. Note that the production capacity of domestic integrated circuits reached 29.09 billion pieces in March, a year-on-year increase of 37.4%. It can be seen that the demand for integrated circuits in the domestic market is strong, and the growth rate of production is relatively large. According to the budget, my country may achieve a self-sufficiency rate of 70% in chips by 2025.
Baoji Yusheng Metal Technology Co., Ltd. has been supplying tungsten targets for many electronic equipment companies at home and abroad for a long time.
