Title: Method for manufacturing semiconductor device
Inventor: TOMIOKA YUGO
IPC: H01L21/76
Filed: 2001-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor device capable of forming an optimized well for a fine MOS transistor and a well formed deeply in relatively low concentration for a high breakdown voltage MOS transistor without increasing the number of steps. SOLUTION: The method for manufacturing the semiconductor device comprises the steps of well ion implanting for a high breakdown voltage MOS transistor before an STI is formed, then heat-treating to recover a crystal defect after filling an insulating film in a trench groove at the time of forming the STI, diffusing a well 108 for the high breakdown voltage MOS transistor, and thereafter forming the well 111 for the fine MOS transistor. Thus, the heat treatment for recovering the crystal defect indispensable to form the STI can be used for diffusing the well for the high breakdown voltage MOS transistor, and the well having the relatively low concentration and being deep can be formed without increasing the number of steps.
