Claim Text:
1. A method for forming a fin field effect transistor (FinFET) device, comprising: forming a set of merged fins from a substrate; forming a set of unmerged fins from the substrate, the set of unmerged fins adjacent the set of merged fins; and forming a planar block from the substrate, the planar block adjacent one of: the set of merged fins, and the set of unmerged fins; wherein forming the set of merged fins, forming the set of unmerged fins, and forming the planar block comprise: forming a first hardmask over the substrate; patterning a plurality of merged fin structures and a planar block structure over the first hardmask; forming a second hard mask over the plurality of merged fin structures and the planar block structure; and depositing a third hardmask over the second hardmask.
