200mm SiC substrate dummy grade 4H-N 8inch SiC wafer

Short Description:

Silicon carbide substrate with a diameter of 8 inches (about 200 mm). Silicon carbide (SiC) substrate is an important material for manufacturing power devices and optoelectronic devices. 8-inch SiC substrates are commonly used to manufacture high-power electronic devices such as power MOSFETs, power diodes, and other high-performance power devices. This large-size substrate can improve production efficiency, reduce manufacturing costs, and help enable the manufacture of more powerful devices. Silicon carbide material has excellent thermal conductivity, high temperature resistance and radiation resistance, making it an ideal choice for manufacturing high performance power devices.

The technical difficulties of 8-inch SiC substrate production include:

1.Crystal Growth: Achieving high-quality single crystal growth of silicon carbide in large diameters can be challenging due to the control of defects and impurities.

2.Wafer Processing: The larger size of 8-inch wafers presents challenges in terms of uniformity and defect control during wafer processing, such as polishing, etching, and doping.

3.Material Homogeneity: Ensuring consistent material properties and homogeneity across the entire 8-inch SiC substrate is technically demanding and requires precise control during the manufacturing process.

4.Cost: Scaling up to 8-inch SiC substrates while maintaining high material quality and yield can be economically challenging due to the complexity and cost of the production processes.

5.Addressing these technical difficulties is crucial for the widespread adoption of 8-inch SiC substrates in high-performance power and optoelectronic devices.
