Classification: CPC H  C | IPC H

Claim 0:
1. A SiC laminate, comprising:
a single crystal hexagonal SiC layer; and
a single crystal 3C-SiC layer overlaid on the hexagonal SiC layer, wherein
the 3C-SiC layer does not contain a twin boundary,
a heterointerface where the 3C-SiC layer and the hexagonal SiC layer meet is exactly parallel to close-packed planes (CPPs) of crystal lattices of the layers and is a lattice-matched coherent heterointerface,
the coherent heterointerfaces is exposed on a main surface at an inclination angle of 0.5 degrees or more and less than 73 degrees, and
a segment of the coherent heterointerface on the main surface is a polygon or a straight line with no endpoint and separates a hexagonal SiC surface and a 3C-SiC surface.
