Abstract
One illustrative method disclosed herein includes, among other things, forming a plurality of trenches in a semiconductor substrate so as to define a plurality of fins, forming a recessed layer of insulating material comprising a first insulating material in the trenches, wherein a portion of each of the plurality of fins is exposed above an upper surface of the recessed layer of insulating material, and masking a first portion of a first fin and performing at least one first etching process to remove at least a portion of an unmasked second fin. In this example, the method further includes forming a device isolation region for the FinFET device that comprises a second insulating material and forming an isolation protection layer above the device isolation region.
