  • SEMICONDUCTOR DEVICE
    Publication number: 20200373433
    Abstract: A semiconductor device with favorable electrical characteristics is provided. A semiconductor device with stable electrical characteristics is provided. The semiconductor device is configured to include a first insulating layer, a second insulating layer, a third insulating layer, a first conductive layer, and a semiconductor layer. The semiconductor layer is positioned over the first insulating layer. The first conductive layer is positioned over the semiconductor layer. The second insulating layer covers a side surface and a bottom surface of the first conductive layer. The third insulating layer is in contact with a top surface of the first insulating layer and part of a top surface of the semiconductor layer and covers a side surface of the second insulating layer. The semiconductor layer contains a metal oxide, the first insulating layer and the second insulating layer each contain an oxide, and the third insulating layer contains a metal nitride.
