Customized SiC Epitaxial Wafers on SiC Substrates

SKU: CS0081

To better serve you, we would like to discuss your specific requirement.
Please Contact Us for a quote.

Customized silicon carbide SiC epitaxial wafers can be provided by MSE Supplies to meet your specific project requirements. Both semi-insulating and N-type SiC substrates are available. The epitaxial SiC layer can also be grown with the CVD process to be either N-type or P-type with controlled doping concentration and layer thickness.Wafer characterization reports based on advanced analytical methods, such as SIMS and XRD, are available to guarantee the quality of our SiC epi wafers

SiC epitaxial wafers have the advantages of operating under high-voltage, high electric current, and at high temperatures compared to semiconductor devices based on silicon. These unique features of SiC epitaxial wafers lead to the miniaturization of devices, enabling smaller and lighter power control modules to be made.

Customer Success Story: NASA uses custom-made SiC epitaxial wafers and SiC substrates supplied by MSE Supplies to develop high temperature and smart silicon carbide electronics and sensors.
