Abstract
A semiconductor device includes a substrate having a first upper surface; a semiconductor layer provided on the substrate; a first insulator layer provided over the semiconductor layer and having a second upper surface; a lower electrode provided over the first insulator layer; a dielectric layer provided on the lower electrode; and an upper electrode provided on the dielectric layer. A difference between a maximum value and a minimum value of a distance between the first upper surface of the substrate and the second upper surface of the first insulator layer is smaller than a thickness of the semiconductor layer.
