What are the Three Generations of Semiconductor Materials? The first generation of semiconductor material The first generation of semiconductor materials mainly refers to silicon (Si) and germanium (Ge) materials. In the 1950s, Ge dominated the semiconductor market and was mainly used in low-voltage, low-frequency, medium-power transistors and photodetectors. However, Ge semiconductor devices were inferior in...Continue Reading

Semiconductor materials can be divided into wafer materials and packaging materials. Compared with wafer manufacturing materials, packaging materials have relatively low technical barriers, so we mainly talk about wafer manufacturing materials. The production of wafer mainly involves 7 kinds of semiconductor materials and chemicals, each of which accounts for the following proportion in the semiconductor...Continue Reading
