Claim Text:
1. A method, comprising: forming a plurality of fins in a semiconducting substrate, each of which has a corresponding masking layer feature positioned thereabove; forming at least one patterned layer of material above said plurality of fins, wherein said at least one patterned layer of material has an opening that exposes at least two fins of said plurality of fins; performing an angled etching process through said opening in said at least one patterned layer of material so as to remove said masking layer feature formed above one of said at least two exposed fins, and thereby define an exposed fin, while leaving said masking layer feature intact above the other of said at least two exposed fins; performing an anisotropic etching process through said opening in said at least one patterned layer of material to remove said exposed fin while leaving the other of said at least two exposed fins intact; and forming a layer of insulating material in at least a portion of the space previously occupied by the removed exposed fin.
