A method for manufacturing a semiconductor device is disclosed, in which characteristics of the semiconductor device and an operation speed are improved. In forming sidewall spacers at both sides of a gate electrode, a semiconductor substrates is partially removed at both sides of the sidewall spacer by controlling an etch gas, and then a process for forming a silicide layer is performed, thereby increasing a distance between the silicide layer and a channel. Accordingly, it is possible to decrease a resistance material between the silicide layer and the channel region.
