Title: Semiconductor device and its manufacture
Inventor: NAGAYAMA TETSUJI
IPC: H01L21/28
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To prevent a contact hole from penetrating a side wall spacer or LOCOS due to deviation in alignment at the time of making the contact hole in an insulating film by extending creep-up sections of a silicide layer over the side wall spacer or LOCOS when forming the silicide layer in an impurity diffusion layer region and using the creep-up sections as an etching stopper. SOLUTION: In an impurity diffusion layer region which is formed on a substrate 1 and is partitioned by a side wall spacer 6 and a LOCOS 7, a silicide layer 8 is formed. At that time, the length of creep-up sections 8a of the silicide layer which are extended over the side wall spacer 6 and the LOCOS 7 are made nearly twice the length in a normal silicide process or above. By this method, when forming a contact hole 10 which faces the silicide layer 8 after forming an interlayer insulating film 9, the contact hole 10 can be prevented from breaking through the side wall spacer 6 or LOCOS 7 even if there is a deviation in positioning of a resist mask since the creep-up sections 8a formed at both sides of the silicide layer 8 have sufficient margins for compensating the deviation in positioning of the resist mask.
