Title: Semiconductor device and manufacture thereof
Inventor: TANAKA YASUSHI
IPC: H01L29/78
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent salicide leakage which is caused through a silicide film at the end of an element isolation layer. SOLUTION: A side wall insulation film 4a is formed in the exposed part on a silicon substrate 1, among the side walls of an STI film 4. Silicide films 8a and 9a are formed by carrying out siliciding reaction for the surfaces of a source 8 and a drain 9 using the side wall insulation film 4a as a mask. Thus, the ends of the source 8 and the drain 9 can be prevented from forming the silicide film because siliciding reaction doesn't occur on the part covered with the sidewall insulation film 4a. Thereby, the silicide films 8a and 9a can terminate on the surface of the source 8 and the drain 9, and salicide leakage can be prevented.
