Patent number: 10297454Abstract: A method is provided for fabricating a semiconductor device. The method includes providing a base substrate including a dummy gate electrode and an interlayer dielectric layer covering a sidewall of the dummy gate electrode. The method also includes forming a sacrificial layer covering a top surface of the interlayer dielectric layer by using a selective atomic layer deposition process, wherein the sacrificial layer exposes a top surface of the dummy gate electrode. In addition, the method includes forming an opening by using the sacrificial layer as an etch mask to remove the dummy gate electrode, and forming a metal gate electrode on the sacrificial layer and in the opening. Further, the method includes planarizing the metal gate electrode and the sacrificial layer until a top surface of the metal gate electrode is leveled with the top surface of the interlayer dielectric layer.Type: GrantFiled: October 27, 2016Date of Patent: May 21, 2019Assignees: SEMICONDUCTOR MANUFACTURING INTERNATIONAL (SHANGHAI) CORPORATION, SEMICONDUCTOR MANUFACTURING INTERNATIONAL (BEIJING) CORPORATIONInventors: Feng Lian Li, Jing Hua Ni
