Abstract
To provide a semiconductor device capable of reducing a parasitic capacitance, securing high reliability, and suppressing an increase in manufacturing cost. A semiconductor device is provided which includes a substrate including an embedded insulation film and a semiconductor layer on the embedded insulation film and on which a semiconductor element is formed and a gate electrode on the semiconductor layer, in which the gate electrode includes a band-shaped first electrode portion that extends from a center portion of the semiconductor layer and beyond an end of the semiconductor layer along a first direction in a case where the substrate is viewed from above, and in a cross section in a case where the first electrode portion and the substrate are cut along the first direction, a film thickness of the end of the semiconductor layer is thicker than a film thickness of the center portion of the semiconductor layer.
