Semiconductors have applications in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors.
No matter from the perspective of science and technology or economic development, the importance of semiconductors is enormous. Most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors.
Common semiconductor materials are silicon, germanium, gallium arsenide and so on. Silicon is one of the most influential semiconductor materials.
Development history of China
China's electronic information industry appeared in the 1920s. 1929 10 the Ministry of military and political affairs of the Kuomintang government of China set up the "General Telecommunication Machinery Repair Factory" in Nanjing, mainly producing military transceivers, and later set up scientific research and production units such as Central Radio Equipment Co., Ltd. and Nanjing Radar Research Institute. After the founding of People's Republic of China (PRC), the government attached great importance to the development of electronic industry.
Initially, the General Telecommunications Bureau was established in the People's Revolutionary Military Commission of the Central People's Government to take over the 1 1 radio enterprises left over by bureaucratic capital, and merged with the original revolutionary base radio equipment repair shop to resume production.
1950 10 in June, the State Council, China decided to set up the Telecommunications Industry Bureau in the Ministry of Heavy Industry. 1963, China decided to establish the Fourth Ministry of machinery industry exclusive to China's defense industry. This indicates that the electronic information industry has become an independent industrial sector in China.
