Abstract

A method for fabricating semiconductor device is disclosed. The method includes the steps of: providing a substrate; forming a first material layer on the substrate; forming a stop layer on the first material layer; forming a second material layer on the stop layer; and performing a planarizing process to remove the second material layer, the stop layer, and part of the first material layer for forming a gate layer.
