Abstract:
A method for producing a semiconductor device comprising the steps of:forming a semiconductor island on an insulating surface;selectively forming a gate insulating film on said semiconductor island;selectively forming a gate electrode portion on said gate insulating film;selectively removing portions of said gate insulating film until a width of said gate insulating film is the same as a width of said gate electrode;forming a metal film which covers the semiconductor island, the gate insulating film and the gate electrode portion;selectively introducing an N-type or P-type impurity element into the semiconductor island through the metal film in a slanting direction with respect to a major surface of said insulating surface, wherein said gate insulating film with edges of said gate electrode portion to define a width of a source and drain region in said semiconductor island;selectively reacting the metal film with the semiconductor island to selectively form a silicide region in the semiconductor island;removing a portion of the metal film that has not reacted in the reacting step,wherein said slanting direction is an angle of 30.degree. or more with respect to the major surface of the insulating surface.
