Semiconductor refers to a material whose conductivity is between a conductor and an insulator at room temperature. Semiconductors are widely used in radios, televisions and temperature measurement. For example, a diode is a device made of semiconductors. Semiconductor refers to a material whose conductivity can be controlled, ranging from insulators to conductors. Whether from the perspective of technology or economic development, the importance of semiconductors is huge. Most of today's electronic products, such as computers, mobile phones, or digital tape recorders, have a very close connection with semiconductors. Common semiconductor materials include silicon, germanium, gallium arsenide, etc., and silicon is the most influential in commercial applications among various semiconductor materials.
1. At present, China is the world's largest consumer of semiconductors, consuming 45% of the global market share of semiconductor chips every year.
2. 90% of China's semiconductor chip consumption is dependent on imports, which far exceed oil imports.
3. China's semiconductor chips started relatively late, lagging behind the world average.
4. The world's semiconductor giants have formed a complete ecological chain, and the commercialization of Chinese semiconductor companies is difficult.
Who is the leading semiconductor in China?At present, the leading semiconductor in China is Ziguang Group. Ziguang Co., Ltd. is a high-tech A-share listed company approved by the State Economic and Trade Commission and the Ministry of Education. Its predecessor was Tsinghua University Technology Development Corporation established in 1988. Tsinghua Unigroup (Group) Corporation was reorganized in 1993 and listed on the Shenzhen Stock Exchange on November 4 of the same year (stock abbreviation G Unisplendour, stock code 000938).
