摘要:
A space is provided under part of a semiconductor layer. Specifically, a structure in which an eaves portion (a projecting portion, an overhang portion) is formed in the semiconductor layer. The eaves portion is formed as follows: a stacked-layer structure in which a conductive layer, an insulating layer, and a semiconductor layer are stacked in this order is etched collectively to determine a pattern of a gate electrode; and a pattern of the semiconductor layer is formed while side-etching is performed.
