Semiconductor refers to a material whose conductivity can be controlled from insulator to conductor. No matter from the perspective of science and technology or economic development, the importance of semiconductors is very great. Most of today's electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is one of the most influential semiconductor materials in commercial applications.
The most advanced integrated circuit is the core of microprocessor or multi-core processor, which can control everything from computer to mobile phone to digital microwave oven. Although the cost of designing and developing a complex
We usually refer to metals with good conductivity such as gold, silver, copper, iron, tin and aluminum as conductors. At the same time, materials with poor conductivity, such as coal, artificial crystals, amber, ceramics, etc., are called insulators. Then, we can simply call the material between the conductor and the insulator semiconductor.
Semiconductor refrigeration technology is widely used in the current refrigeration technology. During the growth of crops in the greenhouse, semiconductor refrigeration technology can effectively control the environmental temperature, especially for some plants with high requirements for the environment
IC chip (integrated circuit) is an integrated circuit formed by putting a large number of microelectronic components (transistors, resistors, capacitors, diodes, etc.) on a plastic base to make a chip. At present, almost all chips can be called IC chips.
What is the status of Chinese chips On June 9, 2021, at the world semiconductor conference, Wu Hanming, an academician of the Chinese Academy of engineering, pointed out the current situation of China's chips: China still needs 8 SMIC's if it wants to complete the localization and replacement of chips. In short, now China needs 8 SMIC's
