Claim Text:
1. A method for manufacturing a semiconductor device, the method comprising the steps of: forming a semiconductor film over a substrate; forming a conductive film over the semiconductor film; etching the semiconductor film and the conductive film consecutively by dry etching after forming the conductive film; forming an insulating film over the etched conductive film after etching the semiconductor film and the conductive film consecutively; etching the insulating film by anisotropic etching to form a sidewall which covers a side surface of the semiconductor film and to expose the conductive film after forming the insulating film; after the anisotropic etching forming a source electrode layer and a drain electrode layer by etching the conductive film whose side surface is covered by the sidewall; and forming a pixel electrode layer electrically connected to one of the source electrode layer and the drain electrode layer.
