SILICON CARBIDE SUBSTRATE PRODUCTION METHOD AND SILICON CARBIDE SUBSTRATE

摘要

A method for manufacturing a silicon carbide substrate (1) includes the steps of: preparing a plurality of SiC substrates (20) each made of single-crystal silicon carbide; forming a base layer (10) made of silicon carbide and holding the plurality of SiC substrates (20), which are arranged side by side when viewed in a planar view; and forming a filling portion (60) filling a gap between the plurality of SiC substrates (20).
