Abstract:
An object is to provide favorable interface characteristics of a thin film transistor including an oxide semiconductor layer without mixing of an impurity such as moisture. Another object is to provide a semiconductor device including a thin film transistor having excellent electric characteristics and high reliability, and a method by which a semiconductor device can be manufactured with high productivity. A main point is to perform oxygen radical treatment on a surface of a gate insulating layer. Accordingly, there is a peak of the oxygen concentration at an interface between the gate insulating layer and a semiconductor layer, and the oxygen concentration of the gate insulating layer has a concentration gradient. The oxygen concentration is increased toward the interface between the gate insulating layer and the semiconductor layer.

Claim (Index 2):
A semiconductor device comprising:\n a gate electrode layer; a gate insulating layer over the gate electrode layer; an oxide semiconductor layer over the gate electrode layer with the gate insulating layer therebetween, the oxide semiconductor layer comprising indium and zinc; a source region over the oxide semiconductor layer; a drain region over the oxide semiconductor layer, wherein each of the source region and the drain region comprises indium and zinc; a source electrode layer on the source region; and a drain electrode layer on the drain region, wherein each of the source region and the drain region comprises crystal grains having a diameter of 1 nm to 10 nm, wherein the oxide semiconductor layer extends beyond outer side edges of the source region and the drain region, wherein the source region extends beyond an outer side edge of the source electrode layer, and wherein the drain region extends beyond an outer side edge of the drain electrode layer.
