Abstract:
A semiconductor device includes a semiconductor substrate and a semiconductor fin on the semiconductor substrate and a fin isolation structure on the semiconductor substrate. The fin isolation structure has an air gap dividing the semiconductor fin into two portions of the semiconductor fin, in which the air gap extends into the semiconductor substrate for a distance. The fin isolation structure includes a dielectric cap layer capping a top of the air gap, in which the dielectric cap layer is spaced apart from a bottom of the air gap.

Claim (Index 17):
A method for forming a semiconductor device, the method comprising:\n forming a semiconductor fin on a semiconductor substrate; forming a first gate conductor, a second gate conductor and a third gate conductor separately on a top of the semiconductor fin, wherein the second gate conductor is located between the first gate conductor and the third gate conductor; forming a first gate spacer peripherally enclosing the first gate conductor, a second gate spacer peripherally enclosing the second gate conductor, and a third gate spacer peripherally enclosing the third gate conductor; etching the first gate conductor, the third gate conductor and their corresponding portions of the semiconductor fin to form an opening extending from the top of each of the corresponding portions of the semiconductor fin to into the semiconductor substrate for a distance, thereby dividing each of the corresponding portions of the semiconductor fin into two portions of the semiconductor fin; and depositing a dielectric cap layer into the opening to cap a top of the opening, wherein the dielectric cap layer is spaced apart from a bottom of the opening.
