在finFET器件和所产生的器件之间形成单个扩散断裂的方法

Method for forming single diffusion breaks between finFET devices and the resulting devices
Abstract:
A method includes forming a fin in a semiconductor substrate. A plurality of sacrificial gate structures are formed above the fin. A selected one of the sacrificial gate structures is removed to define a first opening that exposes a portion of the fin. An etch process is performed through the first opening on the exposed portion of the fin to define a first recess in the fin. The first recess is filled with a dielectric material to define a diffusion break in the fin. A device includes a fin defined in a substrate, a plurality of gates formed above the fin, a plurality of recesses filled with epitaxial material defined in the fin, and a diffusion break defined at least partially in the fin between two of the recesses filled with epitaxial material and extending above the fin.
