Semiconductor devices and methods of manufacture

Abstract

Semiconductor devices and methods of manufacturing the semiconductor devices are described herein. A method includes forming a first etch stop layer from a portion of a gate mask, the gate mask extending between spacers adjacent a gate electrode, the gate electrode overlying a semiconductor fin. The method further includes forming a second etch stop layer adjacent the first etch stop layer, forming an opening through the second etch stop layer, and exposing the first etch stop layer by performing a first etching process. The method further includes extending the opening through the first etch stop layer and exposing the gate electrode by performing a second etching process. Once the gate electrode has been exposed, the method further includes forming a gate contact in the opening.
