Abstract
Provided is a manufacturing method for manufacturing a SiC substrate having a flattened surface, including etching the surface of the SiC substrate by irradiating the surface of the SiC substrate with atomic hydrogen while the SiC substrate having an off angle is heated. In the etching, the SiC substrate may be heated within a range of 800° C. or higher and 1200° C. or lower.
