SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING SAME

摘要

A semiconductor device includes: an insulating substrate; a stepwise layer arranged on the insulating substrate and having an end portion whose inclination angle is equal to or greater than 60°; an insulating layer formed on the insulating substrate and the stepwise layer so as to be elevated on the stepwise layer; a first semiconductor layer arranged at a portion adjacent to the elevated insulating layer; and a second semiconductor layer structured with a material identical to that of the first semiconductor layer, and formed in an island shape on the elevated insulating layer.
