A method of making a semiconductor device includes patterning a fin in a substrate; performing a first etch to remove a portion of the fin to cut the fin into a first cut fin and a second cut fin, the first cut fin having a first and second fin end and the second cut fin having a first and second fin ends; forming an oxide layer along an endwall of the first fin end and an endwall of the second fin end of the first cut fin, and an endwall of the first fin end and an endwall of the second fin end of the second cut fin; disposing a liner onto the oxide layer disposed onto the endwall of the first fin end of the first cut fin to form a bilayer liner; and performing a second etch to remove a portion of the second cut fin.
