Abstract:
1. An integrated circuit, comprising: a substrate region; a gate electrode level region formed above the substrate region, the gate electrode level region including four linear-shaped conductive structures each formed to extend lengthwise in a first direction, wherein each of the four linear-shaped conductive structures is positioned within an area of the gate electrode level region having a radius up to about 965 nanometers, wherein the four linear-shaped conductive structures include— a first linear-shaped conductive structure having one gate portion, a first extending portion, and a second extending portion, wherein the first and second extending portions of the first linear-shaped conductive structure extend in the first direction in opposite directions away from the gate portion of the first linear-shaped conductive structure, wherein the gate portion of the first linear-shaped conductive structure forms a gate electrode of a first transistor of a first transistor type, a second linear-shaped conductive structure having one gate portion, a first extending portion, and a second extending portion, wherein the first and second extending portions of the second linear-shaped conductive structure extend in the first direction in opposite directions away from the gate portion of the second linear-shaped conductive structure, wherein the gate portion of the second linear-shaped conductive structure forms a gate electrode of a first transistor of a second transistor type, a third linear-shaped conductive structure having one gate portion, a first extending portion, and a second extending portion, wherein the first and second extending portions of the third linear-shaped conductive structure extend in the first direction in opposite directions away from the gate portion of the third linear-shaped conductive structure, wherein the gate portion of the third linear-shaped conductive structure forms a gate electrode of a second transistor of the first transistor type, a fourth linear-shaped conductive structure having one gate portion, a first extending portion, and a second extending portion, wherein the first and second extending portions of the fourth linear-shaped conductive structure extend in the first direction in opposite directions away from the gate portion of the fourth linear-shaped conductive structure, wherein the gate portion of the fourth linear-shaped conductive structure forms a gate electrode of a second transistor of the second transistor type, wherein the first and second transistors of the first transistor type are separated from the first and second transistors of the second transistor type by a non-diffusion area of the substrate region located between transistors of the first transistor type and transistors of the second transistor type, wherein the first extending portions of the first, second, third, and fourth linear-shaped conductive structures extend over the non-diffusion area of the substrate region, and wherein the second extending portions of the first, second, third, and fourth linear-shaped conductive structures extend away from the non-diffusion area of the substrate region, wherein at least one of the first, second, third, and fourth linear-shaped conductive structures is an inner-contacted conductive structure having its first extending portion physically connected to a contacting structure at a location over the non-diffusion area of the substrate region, wherein at least one of the first, second, third, and fourth linear-shaped conductive structures is an outer-contacted conductive structure having its second extending portion physically connected to a contacting structure at a location away from the non-diffusion area of the substrate region, and wherein at least one of the first, second, third, and fourth linear-shaped conductive structures that is one of the outer-contacted conductive structures has a length of its second extending portion as measured in the first direction greater than a length of its first extending portion as measured in the first direction.
