METHOD FOR FABRICATING SEMICONDUCTOR DEVICE |
摘要 |
A method of fabricating a semiconductor device is disclosed. The method includes the steps of: sequentially forming agate dielectric layer and a first gate layer on a semiconductor substrate, wherein the gate dielectric layer is between the first gate layer and the semiconductor substrate; forming at least an opening in the first gate layer; forming a first dielectric layer conformally on the semiconductor substrate wherein the first dielectric layer covers the first gate layer; and forming a second gate layer filling the opening and overlapping the first gate layer. |
