Semiconductor device and method for fabricating the same

摘要

A method for fabricating a semiconductor device includes the steps of forming a high-k layer insulating layer on a SOI substrate; forming a gate electrode layer on the high-k insulating layer; forming a resist layer on the gate electrode layer; removing selectively the gate electrode layer using the resist layer as a mask; and removing the resist layer by an ashing process using a gas that does not comprise oxygen.
