Abstract:
A method for fabricating a Fin-FET device includes forming a plurality of discrete fin structures on a substrate which includes a first device region and a second device region, forming a plurality of dummy gate electrodes across the fin structures, and forming an interlayer dielectric layer exposing the dummy gate electrodes on a portion of the fin structures exposed by the dummy gate electrodes, forming a first opening by removing each dummy gate electrode, forming an initial metal gate electrode in the first opening and between adjacent fin structures, and forming a second opening through the initial metal gate electrode. The initial metal gate electrode formed in the first device region is a first metal gate electrode, and the initial metal gate electrode formed in the second device region is a second metal gate electrode. The second opening separates the first metal gate electrode from the second metal gate electrode.

Claim (Index 1):
A method for fabricating a fin field-effect transistor (Fin-FET) device, comprising:\n forming a plurality of discrete fin structures on a substrate, wherein the substrate includes a first device region and a second device region; forming a plurality of dummy gate electrodes across the fin structures to cover a portion of top and sidewall surfaces of each fin structure; forming an interlayer dielectric layer on a portion of the fin structures exposed by the dummy gate electrodes, wherein the interlayer dielectric layer exposes the dummy gate electrodes; forming a first opening in the interlayer dielectric layer by removing each dummy gate electrode; forming an initial metal gate electrode to fill up the first opening and on the substrate between adjacent fin structures; and forming a second opening through the initial metal gate electrode and on the substrate, wherein;\n a portion of the initial metal gate electrode formed in the first device region is a first metal gate electrode, and a portion of the initial metal gate electrode formed in the second device region is a second metal gate electrode, and \n the second opening separates the first metal gate electrode in the first device region from the second metal gate electrode in the second device region.
