Abstract
A semiconductor device with favorable electrical characteristics is provided. A highly reliable semiconductor device is provided. A semiconductor device with stable electrical characteristics is provided. The semiconductor device includes a semiconductor layer, a gate insulating layer, agate electrode, a first insulating layer, a second insulating layer, and a conductive layer. The gate insulating layer is in contact with a top surface and a side surface of the semiconductor layer, and the gate electrode includes a region overlapping with the semiconductor layer with the gate insulating layer therebetween. The first insulating layer contains an inorganic material and is in contact with a top surface of the gate insulating layer and a top surface and a side surface of the gate electrode. The gate insulating layer and the first insulating layer include a first opening in a region overlapping with the semiconductor layer. The second insulating layer contains an organic material and includes a second opening inside the first opening. The second insulating layer is in contact with a top surface and a side surface of the first insulating layer and a side surface of the gate insulating layer. The conductive layer is electrically connected to the semiconductor layer through the second opening.
