Abstract:
A method of manufacturing a transistor in a semiconductor device, comprising the steps of:injecting, by a given depth, ions into an active region in a semiconductor substrate to form an insulating layer; forming a gate insulating film and a gate electrode in a channel region of said semiconductor substrate; forming a LDD region in said semiconductor substrate on said insulating layer; depositing an insulating material on the LDD region to form an insulating film spacer on a sidewall of said gate electrode; performing an etch process so that said LDD region and said insulating layer are etched to form a groove at a side of said spacer; growing an epitaxial silicon layer in said groove and injecting impurity ions into said epitaxial silicon layer to form a junction region; and forming a silicide layer on the surface of each of said gate electrode and said junction region.
