Abstract
In order to provide a method for manufacturing a single crystal SiC substrate that can obtain an SiC layer with good crystallinity, an Si substratehaving a surface Si layerof a predetermined thickness and an embedded insulating layeris prepared, and when the Si substrateis heated in a carbon-series gas atmosphere to convert the surface Si layerinto a single crystal SiC layer, the Si layer in the vicinity of an interfacewith the embedded insulating layeris left as a residual Si layer
