Patent ID: 8829526

Claim:
A semiconductor device, comprising: a substrate; an insulating layer formed on a surface of the substrate; a thin film transistor that is formed on said insulating layer, and that has a semiconductor layer including a channel region, a source region and a drain region, a gate electrode, and a gate insulating film provided between said semiconductor layer and said gate electrode; and a thin film diode that is formed on said insulating layer, and that has a semiconductor layer including at least an n-type region and a p-type region, wherein a first recessed and projected pattern is formed on a surface of said insulating layer in a portion located below the semiconductor layer of said thin film diode, and said first recessed and projected pattern is absent in a portion located below the semiconductor layer of said thin film transistor, and wherein a surface of the semiconductor layer of said thin film diode includes a second recessed and projected pattern reflecting a shape of said first recessed and projected pattern.
