Abstract:
1. A method of manufacturing a semiconductor device comprising: forming a first semiconductor pattern whose upper surface is covered with a first insulating film over a first active region of a semiconductor substrate; forming a second semiconductor pattern over a second active region of the semiconductor substrate; forming a second insulating film over the first insulating film and the first semiconductor pattern and the second semiconductor pattern; forming sidewalls on side surfaces of the second semiconductor pattern by etching the second insulating film; after forming the sidewalls, forming an opening portion reaching the first semiconductor pattern, in the second insulating film and the first insulating film; forming a metal film over the first semiconductor pattern and the second semiconductor pattern respectively; and forming a silicide layer over the first semiconductor pattern and the second semiconductor pattern respectively by reacting the first semiconductor pattern and the second semiconductor pattern with the metal film.
