Abstract:
It is an object to provide an oxide semiconductor which is suitable for use in a semiconductor device. Alternatively, it is another object to provide a semiconductor device using the oxide semiconductor. Provided is a semiconductor device including an In—Ga—Zn—O based oxide semiconductor layer in a channel formation region of a transistor. In the semiconductor device, the In—Ga—Zn—O based oxide semiconductor layer has a structure in which crystal grains represented by InGaO 3 (ZnO) m  (m=1) are included in an amorphous structure represented by InGaO 3 (ZnO) m  (m>0).

Claim (Index 6):
A semiconductor device comprising:\n a first oxide semiconductor layer comprising a channel formation region; and a second oxide semiconductor layer over the first oxide semiconductor layer, wherein the first oxide semiconductor layer comprises a crystal represented by InGaZnO 4 , wherein the first oxide semiconductor layer comprises In, Ga, and Zn, wherein a Zn content by atomic percent in the first oxide semiconductor layer is less than an In content by atomic percent in the first oxide semiconductor layer, wherein the Zn content by atomic percent in the first oxide semiconductor layer is less than a Ga content by atomic percent in the first oxide semiconductor layer, and wherein the first oxide semiconductor layer is formed using a target of In:Ga:Zn=2:2:1 by sputtering method.
