Patent ID: 8729609

Claim:
An integrated circuit, comprising: a substrate; and a plurality of locally interconnected multi-gate transistors, comprising: a continuous fin structure formed on the substrate and comprising an inner open area and an outer perimeter portion, wherein the continuous fin structure has a substantially continuous width across the substrate along the entire length of the continuous fin structure; and first and second multi-gate transistors formed on the substrate and including first and second fin segments of the continuous fin structure, respectively, the continuous fin structure electrically interconnecting the first and second multi-gate transistors, wherein the first and second multi-gate transistors comprise spaced-apart first and second gate structures, respectively, overlying the first and second fin segments of the continuous fin structure, wherein the first gate structure is not physically connected to the second gate structure; a first input electrode electrically coupled to the first gate structure but not to the second gate structure and a second input electrode electrically coupled to the second gate structure but not to the first gate structure; an output electrode electrically coupled to the continuous fin structure; third and fourth multi-gate transistors formed on the substrate and including third and fourth fin segments of the continuous fin structure, respectively, wherein the third multi-gate transistor comprises a third gate structure overlying the third fin segment of the continuous fin structure, the third gate structure electrically coupled to the first input electrode and responsive to the first input signal, wherein the fourth multi-gate transistor comprises a fourth gate structure overlying the fourth fin segment of the continuous fin structure, the fourth gate structure electrically coupled to the second input electrode and responsive to the second input signal, wherein the continuous fin structure comprises a first lateral connecting segment between the first fin segment and the second fin segment, the first lateral connecting segment generally perpendicular to the first fin segment and to the second fin segment, and wherein the continuous fin structure further comprises a second lateral connecting segment between the third fin segment and the fourth fin segment, the second lateral connecting segment generally perpendicular to the third fin segment and to the fourth fin segment, wherein the first lateral connecting segment has a greater length than the second lateral segment such that the continuous fin structure forms a substantially T-shaped configuration.
