Claim 11:
12. The method of claim 11, further comprising forming a gate stack disposed on the device fins, and the first and second dielectric fins, wherein
the forming device fins on a substrate includes forming a first and second device fins longitudinally oriented along a first direction, defining a first and second trenches;
the first and second device fins and the first and second dielectric fins are alternatively configured and are spaced away from each other along a second direction that is orthogonal to the first direction, defining hybrid gaps each spanning between one of the first and second device fins and one of the first and second dielectric fins; and
the forming a gate stack includes forming portions of the gate stack inserted in the hybrid gaps.
