Title: Method of manufacturing semiconductor device
Inventor: SHIBATA TAKUMI
IPC: H01L29/78
Filed: 2001-02-06
Abstract: PROBLEM TO BE SOLVED: To enable to obtain a high aspect ratio and to sufficiently reduce crystal defects near the inner wall of a trench. SOLUTION: A power MOSFET has a trench gate structure wherein a gate electrode 8 is formed in a trench 6 via a gate oxide film 7.

For example, a heat treatment is conducted between 1050 deg.C and 1150 deg.C. Consequently, crystal defects formed on the side wall surface of the trench or near the trench can be repaired without expanding the width of the trench and therefore a high aspect ratio is obtained. At the same time, generation of a leakage current in a PN junction can be prevented and, moreover, decline in the breakdown voltage of the gate oxide film 7 can be prevented.
