Title: Semiconductor device fabrication method
Inventor: TSUGANE HIROAKI
IPC: H01L29/78
Filed: 1990-03-23
Abstract: PURPOSE:To make possible the formation of a lightly-doped region with excellent control and without complicating the process by tapering the resist used for gate interconnection processing and so forming a lightly-doped region in the lower portion of the tapered area that ion species pass through the tapered area. CONSTITUTION:A resist pattern 4 is tapered. From above, ion species 5 are implanted using an ion implantation method to form a lightly-doped region.
