Abstract:
1. An integrated circuit, comprising: a first finfet transistor of a first transistor type; a first finfet transistor of a second transistor type; a second finfet transistor of the first transistor type; a second finfet transistor of the second transistor type, each of the first and second finfet transistors of the first transistor type and each of the first and second finfet transistors of the second transistor type having a respective gate electrode extending lengthwise in a parallel direction, the gate electrodes of the first finfet transistor of the first transistor type and the first finfet transistor of the second transistor type having their lengthwise centerlines substantially aligned to a common gate electrode track extending in the parallel direction, the gate electrodes of the second finfet transistor of the first transistor type and the second finfet transistor of the second transistor type positioned on opposite sides of the common gate electrode track, each of the first and second finfet transistors of the first transistor type formed in part by a respective diffusion fin of a first diffusion type electrically connected to a common node, each of the first and second finfet transistors of the second transistor type formed in part by a respective diffusion fin of a second diffusion type electrically connected to the common node, the diffusion fins of the first diffusion type collectively separated from the diffusion fins of the second diffusion type in the parallel direction by an inner non-diffusion region, the gate electrodes of both the first finfet transistor of the first transistor type and the first finfet transistor of the second transistor type formed by a first conductive structure so as to be electrically connected to each other through the first conductive structure, the gate electrode of the second finfet transistor of the first transistor type formed by a second conductive structure, the gate electrode of the second finfet transistor of the second transistor type formed by a third conductive structure, each of the first, second, and third conductive structures including portions extending over the inner non-diffusion region; a first conductive contacting structure connected to the portion of the second conductive structure that extends over the inner non-diffusion region; and a second conductive contacting structure connected to the portion of the third conductive structure that extends over the inner non-diffusion region, each of the first and second conductive contacting structures respectively defined as either a gate contact or a local interconnect structure.
