Abstract:
1. An integrated circuit, comprising: a first linear-shaped conductive structure forming gate electrodes of both a first p-transistor and a first n-transistor; a second linear-shaped conductive structure that 1) forms a gate electrode of a second p-transistor and does not form any gate electrode of any n-transistor, and 2) is positioned next to and spaced apart from the first linear-shaped conductive structure, and 3) includes an extension portion extending away from the gate electrode of the second p-transistor; a third linear-shaped conductive structure that 1) fowls a gate electrode of a second n-transistor and does not form any gate electrode of any p-transistor, and 2) is positioned next to and spaced apart from the first linear-shaped conductive structure, and 3) includes an extension portion extending away from the gate electrode of the second n-transistor; a fourth linear-shaped conductive structure that 1) forms a gate electrode of a third p-transistor and does not form any gate electrode of any n-transistor, and 2) includes an extension portion extending away from the gate electrode of the third p-transistor; a fifth linear-shaped conductive structure that 1) forms a gate electrode of a third n-transistor and does not form any gate electrode of any p-transistor, and 2) includes an extension portion extending away from the gate electrode of the third n-transistor; a sixth linear-shaped conductive structure that 1) forms gate electrodes of both a fourth p-transistor and a fourth n-transistor, and 2) is positioned next to and spaced apart from each of the fourth and fifth linear-shaped conductive structures, the first, second, third, fourth, fifth, and sixth linear-shaped conductive structures formed to extend lengthwise in a parallel direction; a first contact structure contacting the extension portion of the second linear-shaped conductive structure such that the extension portion of the second linear-shaped conductive structure extends a first distance away from the first contact structure in the parallel direction away from the gate electrode of the second p-transistor; a second contact structure contacting the extension portion of the third linear-shaped conductive structure such that the extension portion of the third linear-shaped conductive structure extends a second distance away from the second contact structure in the parallel direction away from the gate electrode of the second n-transistor; a third contact structure contacting the extension portion of the fourth linear-shaped conductive structure such that the extension portion of the fourth linear-shaped conductive structure extends a third distance away from the third contact structure in the parallel direction away from the gate electrode of the third p-transistor; a fourth contact structure contacting the extension portion of the fifth linear-shaped conductive structure such that the extension portion of the fifth linear-shaped conductive structure extends a fourth distance away from the fourth contact structure in the parallel direction away from the gate electrode of the third n-transistor, wherein at least two of the first, second, third, and fourth distances are different.
