Product Description:
Silicon carbide wafer Sic 6H-P type Off axis: 2.0° toward Production Grade Research Grade
Type 6H-P Sic is made of advanced semiconductor material
preparation process with specific crystal structure and doping
type. Among them, "6H" represents the crystal structure type of
silicon carbide, which belongs to a hexagonal crystal system;
"P-type" indicates that the substrate is doped so that the holes
become the main carrier type. The design with an off-axis Angle of
2.0° helps to optimize the performance of the crystal in a specific
direction to meet the needs of specific application scenarios.
Features:
1. High doping concentration: 6H-P type Sic achieves a high concentration of hole carrier distribution through a specific doping process, which helps to improve the electrical conductivity and switching speed of the device.
2. Low resistivity: Due to the high doping concentration, the substrate exhibits low resistivity, which helps to reduce the energy loss of the device during operation.
3. Good thermal stability: Sic material itself has a very high melting point, making 6H-P substrate can maintain stable performance in high temperature environment.
4. Excellent mechanical properties: Sic material has high hardness, wear resistance and other characteristics, making 6H-P substrate can withstand greater mechanical stress in the manufacturing process.
5. Off-axis Angle optimization: The design of the off-axis Angle is 2.0°, so that the performance of the substrate is optimized in a specific direction, which helps to improve the overall performance of the device.

FAQ:
1. Q: What is Sic 6H-P off-axis to 2.0°?
A: Sic 6H-P off-axis to 2.0° refers to a P-type silicon carbide material with a 6H crystal structure, and its cutting direction deviates from the crystal spindle by 2.0°. This design is designed to optimize specific properties of silicon carbide materials, such as increasing carrier mobility and reducing defect density, to meet the manufacturing needs of high-performance semiconductor devices.
2. Q: What is the difference between P-type and N-type silicon wafers?
A: The main difference between P-type silicon wafers and N-type silicon wafers is that the doping elements are different, P-type boron and N-type phosphorus, resulting in their electrical conductivity and physical properties are different.
