Patent ID: 7247562

Claim:
A method for manufacturing a semiconductor device comprising steps of: forming a gate insulating film over a semiconductor region including source and drain regions; forming a gate electrode over the semiconductor region with the gate insulating film interposed therebetween; forming sidewalls covering at least sides of the gate electrode; etching the gate insulating film by using the sidewalls as a mask to expose an upper surface of the source and drain regions; forming a conductive film over the semiconductor region after exposing the source and drain regions; forming a resist over the conductive film; removing an entire upper portion of the resist to expose an upper surface of the conductive film, said upper surface being located over the gate electrode, thereby leaving a resist mask; etching a portion of the conductive film by using the resist mask so that a portion of the sidewalls is exposed; and etching a portion of the etched conductive film to form source and drain electrodes which are in contact with the source and drain regions.
