摘要： An object is to provide a semiconductor device provided with a thin film transistor having excellent electric characteristics using an oxide semiconductor layer. An In—Sn—O-based oxide semiconductor layer including SiOX is used for a channel formation region. In order to reduce contact resistance between the In—Sn—O-based oxide semiconductor layer including SiOX and a wiring layer formed from a metal material having low electric resistance, a source region or drain region is formed between a source electrode layer or drain electrode layer and the In—Sn—O-based oxide semiconductor layer including SiOX. The source region or drain region and a pixel region are formed using an In—Sn—O-based oxide semiconductor layer which does not include SiOX.

摘要： To improve field effect mobility of an inverted-staggered TFT using amorphous silicon. In an inverted-staggered TFT, a thin amorphous semiconductor layer which is made to have n-type conductivity is formed between a gate insulating film and an amorphous semiconductor layer. By depositing an amorphous semiconductor layer after a substrate over which up to a gate insulating film is formed is exposed to an atmosphere which contains a phosphine gas in a small amount, an amorphous semiconductor layer which contains phosphorus is formed during the early stage of deposition of the amorphous semiconductor layer. The thus obtained amorphous semiconductor layer has the concentration peak of phosphorus around the surface of the gate insulating film.
