Abstract:
A method of forming a fin field effect transistor (finFET) having fin(s) with reduced dimensional variations, including forming a dummy fin trench within a perimeter of a fin pattern region on a substrate, forming a dummy fin fill in the dummy fin trench, forming a plurality of vertical fins within the perimeter of the fin pattern region, including border fins at the perimeter of the fin pattern region and interior fins located within the perimeter and inside the bounds of the border fins, wherein the border fins are formed from the dummy fin fill, and removing the border fins, wherein the border fins are dummy fins and the interior fins are active vertical fins.

Claim (Index 1):
A method of forming arrays of fin field effect transistors (finFETs) having fin(s) with reduced dimensional variations, comprising:\n forming a first array of vertical fins, a second array of vertical fins, and one or more dummy fins on a substrate, wherein the one or more dummy fins are between the first array of vertical fins and the second array of vertical fins; and removing the one or more dummy fins to form a gap between the first array of vertical fins and the second array of vertical fins.
