Abstract:
An object is to provide a semiconductor device using an oxide semiconductor having stable electric characteristics and high reliability. A transistor including the oxide semiconductor film in which a top surface portion of the oxide semiconductor film is provided with a metal oxide film containing a constituent similar to that of the oxide semiconductor film and functioning as a channel protective film is provided. In addition, the oxide semiconductor film used for an active layer of the transistor is an oxide semiconductor film highly purified to be electrically i-type (intrinsic) by heat treatment in which impurities such as hydrogen, moisture, a hydroxyl group, or a hydride are removed from the oxide semiconductor and oxygen which is a major constituent of the oxide semiconductor and is reduced concurrently with a step of removing impurities is supplied.

Claim (Index 7):
A semiconductor device comprising:\n a first gate electrode; a gate insulating layer over the first gate electrode; an oxide semiconductor layer over the gate insulating layer; a first insulating layer over the oxide semiconductor layer; a second insulating layer over the oxide semiconductor layer; a source electrode over the first insulating layer and the second insulating layer; a drain electrode over the first insulating layer and the second insulating layer; and a third insulating layer over the source electrode and the drain electrode, wherein the third insulating layer contains silicon and oxygen, wherein the source electrode is in contact with the oxide semiconductor layer through a first opening of the first insulating layer and the second insulating layer, and wherein the drain electrode is in contact with the oxide semiconductor layer through a second opening of the first insulating layer and the second insulating layer.
