1. An integrated circuit structure, comprising:
a substrate;
a plurality of gate structures above the substrate, the plurality of gate structures comprising:
unidirectional linear gate structures aligned in a first direction, the unidirectional linear gate structures including a first group of unidirectional linear gate structures, each linear gate structure of the first group having a first width and aligned in the first direction, and a second group of unidirectional linear gate structures, each linear gate structure of the second group having a second width and aligned in the first direction, the second width different than the first width; and
wherein the linear gate structures of the first group are arranged in an interleaved fashion with the linear gate structures of the second group in a series that alternates between a linear gate structure of the first group and a linear gate structure of the second group, the series traversing the layer in a second direction perpendicular to the first direction as seen in a plan view of the layer of the unidirectional linear gate structures.
