Patent ID: 6974729

Claim:
A method of forming a fin field effect transistor (FinFET) device, comprising: providing a substrate, comprising a semiconductor layer; forming a plurality of active areas, insulated from each other by field areas, in the semiconductor layer; forming at least one dummy gate on at least one of the active areas, wherein the at least one dummy gate extends beyond the at least one active area so as to form a connection with another dummy gate; forming source and drain regions within the at least one of the active areas, the source and drain regions being self aligned to the dummy gate; covering the substrate with an insulating layer as to leave the dummy gate exposed; and patterning the exposed dummy gate and the semiconductor layer so as to create an open cavity in the insulating layer and in the semiconductor layer and to form a dummy fin and a semiconductor fin aligned to the dummy fin in the cavity, both of the fins extending from the source region to the drain region, thereby exposing the semiconductor layer.
