Abstract

There is provided a semiconductor device including corundum crystal films of good quality. There is provided a semiconductor device including a base substrate, a semiconductor layer, and an insulating film each having a corundum crystal structure. Materials having a corundum crystal structure include many types of oxide films capable of functioning as an insulating film. Since all the base substrate, the semiconductor layer, and the insulating film have a corundum crystal structure, it is possible to achieve a semiconductor layer and an insulating film of good quality on the base substrate.
