Patent ID: 8221546

Claim:
A method comprising: heating a single-crystal SiC substrate to a first temperature of at least 1400° C. in a chamber; introducing a carrier gas, a silicon containing gas and carbon containing gas into the chamber; and epitaxially growing a layer of SiC on a surface of the SiC substrate; wherein the SiC substrate is heated to the first temperature at a rate of at least 30° C./minute; and wherein the surface of the SiC substrate is inclined at an angle of from 1° to 3° with respect to a basal plane of the substrate material; wherein the carrier gas, the silicon containing gas and the carbon containing gas are each introduced into the chamber at a constant flow rate during epitaxial growth and wherein the constant flow rate of each of the gases is established within 10 minutes of introducing any of the gases into the chamber.
