Abstract:
A silicon carbide crystal and a manufacturing method for same are provided. A silicon carbide crystal seed used for the silicon carbide crystal has a crystal-growing surface with a surface roughness (Ra) less than 2.0 nm, and a thickness of the silicon carbide crystal seed is less than 700 μm. Therefore, the silicon carbide crystal grown from the silicon carbide crystal seed by sublimation method (which is also a PVT method) may have low basal plane dislocation (BPD) and low micropipe density (MPD).

Claim (Index 10):
The silicon carbide crystal as recited in  claim 7 , further comprising a buffer layer between the silicon carbide crystal and the silicon carbide crystal seed.
