Abstract:
A method of epitaxially growing a SiC layer on a single crystal SiC substrate is described. The method includes 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. The SiC substrate is heated to the first temperature at a rate of at least 30° C./minute. 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.
