Abstract:
1. A semiconductor device, comprising: a number of N-diffusion and a number of P-diffusion defined in a region of the semiconductor device, the number of N-diffusion arranged relative to the number of P-diffusion such that an inner non-diffusion region exists between the number of N-diffusion collectively and the number of P-diffusion collectively; at least four linear shapes extending along a first direction in a gate layer region of the region of the semiconductor device such that each of the at least four linear shapes has its lengthwise centerline extending in the first direction, and wherein some of the at least four linear shapes are gate defining shapes, and some of the gate defining shapes forming P-transistors with respective ones of the number of P-diffusion, and some of the gate defining shapes forming N-transistors with respective ones of the number of N-diffusion, the at least four linear shapes including— a first gate defining shape including a gate portion that forms a gate electrode of a first transistor and an extending portion that extends away from the gate electrode of the first transistor by a first extension length as measured in the first direction, a second gate defining shape including a gate portion that forms a gate electrode of a second transistor and an extending portion that extends away from the gate electrode of the second transistor by a second extension length as measured in the first direction, a third gate defining shape including a gate portion that forms a gate electrode of a third transistor and an extending portion that extends away from the gate electrode of the third transistor by a third extension length as measured in the first direction, a fourth gate defining shape including a gate portion that forms a gate electrode of a fourth transistor and an extending portion that extends away from the gate electrode of the fourth transistor by a fourth extension length as measured in the first direction, and wherein at least two of the first, second, third, and fourth extension lengths are different.
