Semi-conductor materials can be divided into two categories: elemental semiconductors and compound semiconductors. The former includes semiconductors formed from elements such as silicon (Si) and germanium (Ge), while the latter includes compounds such as gallium arsenide (GaAs), gallium nitride (GaN), and silicon carbide (SiC). In the past, semiconductors have undergone three generations of changes, gallium … Read more

Before we explain semiconductor chips, we should first understand two points. First, what is a semiconductor? Second, what is a chip? Semiconductor A semiconductor (semiconductor) refers to a material with electrical conductivity between that of an insulator (insulator) and a conductor (conductor) at room temperature. Materials with poor conductivity, such as coal, artificial crystals, amber, … Read more
Semiconductor materials are a class of materials that possess semiconductor properties (the conductivity is between that of conductors and insulators, with resistivity ranging from approximately 1 mΩ·cm to 1 GΩ·cm). Generally, the conductivity increases with rising temperature. Semiconductor materials have characteristics such as thermal sensitivity, optical sensitivity, and doping capability. They are important materials used … Read more
