Semiconductor materials refer to materials with special electrical properties in electronics and quantum mechanics, including silicon, germanium, silicon nitride, gallium selenide, etc. The special properties of these materials enable them to be used as materials in electronic devices, such as transistors, diodes, solar cells, etc.

There are many forms of matter, such as solid, liquid, gas, plasma and so on. We usually call materials with poor conductivity, such as coal, artificial crystal, amber, ceramics and so on, insulators. Metals with good conductivity, such as gold, silver, copper, iron, tin and aluminum, are called conductors. The material between conductor and insulator can be simply called semiconductor. Compared with conductors and insulators, the discovery of semiconductor materials is the latest. Until the 1930s, when the purification technology of materials was improved, the existence of semiconductors was really recognized by the academic community.

When troubleshooting non-functional or poorly performing circuits, engineers can usually run simulations or other analysis tools to consider the circuit from the schematic level.

After the invention and mass production of transistors, various solid-state semiconductor components such as diodes and transistors were widely used, replacing the functions and roles of vacuum tubes in circuits. By the middle and late 20th century

Our reporter Shen Cong reported: the American Semiconductor Industry Association (SIA) recently released the data of the global chip market in the first quarter of 2022. The data show that the growth rate of the global chip market has slowed down significantly
