Abstract:
A method for producing a semiconductor epitaxial wafer, including steps of: fabricating an epitaxial wafer by epitaxially growing a semiconductor layer on a silicon-based substrate; observing the outer edge portion of the fabricated epitaxial wafer; and removing portions in which a crack, epitaxial layer peeling, and a reaction mark observed in the step of observing are present. As a result, a method for producing a semiconductor epitaxial wafer in which a completely crack-free semiconductor epitaxial wafer can be obtained, is provided.

Claim (Index 1):
A semiconductor epitaxial wafer in which a semiconductor layer is, epitaxially grown on a silicon-based substrate, wherein\n at an outer edge portion of the semiconductor epitaxial wafer, at least part of the semiconductor layer is removed.
