Wafer Substrate is a wafer made of semiconductor single crystal material. The substrate can directly enter the wafer manufacturing process to produce semiconductor devices, or it can be processed by epitaxial process to produce epitaxial wafers.

Wafer Substrate, as the basic supporting structure of semiconductor devices, directly affects the performance and stability of the devices. As the "foundation" for semiconductor device manufacturing, a series of manufacturing processes such as thin film growth and lithography need to be carried out on the substrate.

Summary of substrate types:

1. Single crystal silicon wafer: currently the most common substrate material, widely used in the manufacture of integrated circuits (ICs), microprocessors, memories, MEMS devices, power devices, etc.;

2. SOI substrate: used for high-performance, low-power integrated circuits, such as high-frequency analog and digital circuits, RF devices and power management chips;

3. Compound semiconductor substrates: Gallium arsenide substrate (GaAs): microwave and millimeter wave communication devices, etc. Gallium nitride substrate (GaN): used for RF power amplifiers, HEMT, etc. Silicon carbide substrate (SiC): used for electric vehicles, power converters and other power devices Indium phosphide substrate (InP): used for lasers, photodetectors, etc.;

4. Sapphire substrate: used for LED manufacturing, RFIC (radio frequency integrated circuit), etc.;
