3'' 4'' 350um 500um SSP DSP 4H- 6H- Research Dummy Grade SIC
Epitaxial Substrates
Features of SIC Wafers:
Wide-band gap silicon carbide semiconductors are used to control
and switch high-power electrical equipment. They offer several
advantages over traditional silicon devices, including higher
operating temperatures, higher breakdown voltages, faster switching
speeds, lower on-off resistance, and higher durability. SiC devices
are an innovative option to improve system efficiency, reduce
design size and withstand higher operating temperatures for
industrial, transportation, automotive, medical, aerospace, defense
and communications products.
Main features:
- Extremely low switching losses increase system efficiency
- High power density reduces size and weight
- Three times the thermal conductivity of silicon
- Reduce sink requirements for a smaller footprint and lighter weight
- High temperature operation increases reliability and increases
power density
