Patent JP-H11312788-A (JP)
Title: Manufacture of semiconductor element
Inventor: RI KEIREI
IPC: H01L27/04
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for an exclusive photo-engraving process to a silicide blocking film, and to simplify the process and reduce cost by selectively etching the silicide blocking film by utilizing the photo-engraving process for forming source-drain regions. SOLUTION: Photosensitive film patterns 114a are formed on the whole surface of regions except the surface of a silicide blocking film (SBL) 112 in a first transistor forming section I in a logic forming section B so that the surface of the silicide blocking film is exposed by a photo-engraving process. The SBL 112 in the first transistor forming section I is etched while using the photosensitive film patterns 114a as masks. The ions of first conductivity type impurities in high concentration are implanted to a substrate 100 while employing the photosensitive film patterns 114a as masks. Consequently, source- drain regions are formed into the substrate 100 on both sides of a gate electrode 106 in the first transistor forming section I. Accordingly, an exclusive photo-engraving process to the silicide blocking film is made unnecessary.
