What is a semiconductor material

Semiconductor materials are a class of electronic materials with semiconductor properties that can be used to make semiconductor devices and integrated circuits. Its electrical conductivity is between conductors and insulators.

Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their electrical conductivity. The resistivity of the semiconductor is in the range of 1 mΩ·cm to 1 GΩ·cm. In general, the conductivity of semiconductors increases with temperature, which is the exact opposite of metallic conductors.

All materials with the above two characteristics can be classified into the scope of semiconductor materials. It is a variety of external factors, such as light, heat, magnetism, electricity, etc., that reflect the intrinsic basic properties of semiconductor materials. The physical effects and phenomena caused by these factors acting on semiconductors can be collectively referred to as the semiconductor properties of semiconductor materials. Most of the matrix materials constituting solid-state electronic devices are semiconductors, and it is the various semiconductor properties of these semiconductor materials that endow various types of semiconductor devices with different functions and properties.

What are the common semiconductor materials

There are many semiconductor materials, common semiconductor materials are silicon , germanium , compound semiconductors, such as gallium arsenide,etc. Doping or making other compound semiconductor materials, such as boron, phosphorus, indium and antimony ,etc. Among them, silicon is the most commonly used semiconductor material.

The classification of semiconductors can be divided into: integrated circuit devices, discrete devices, optoelectronic semiconductors, logic ICs, analog ICs, memory and other categories according to their manufacturing technology. In addition, there are classification methods such as application fields and design methods. Although they are not commonly used, they are classified according to IC, LSI, VLSI (very large LSI) and their scale. In addition, there is a method that can be classified into analog, digital, analog-digital hybrid, and function according to the signal to be processed.

The semiconductor industry is developed based on electronic information, and absolute precision is crucial for semiconductor equipment. CNC precision machining can manufacture and process semiconductor elements by machining silicon, aluminum oxide, aluminum nitride, silicon nitride and other materials that have electrical conductivity between conductors and insulators. Semiconductor CNC machining parts are widely used in various electronic components and integrated circuits.
