Classification: CPC H | IPC H

Claim 14:
15. An apparatus comprising:
a first active region;
a second active region;
an isolation region between the first and second active regions;
a third active region adjacent to the first active region and across from the second active region separated by the isolation region;
a plurality of first gate structures disposed on the first active region and the isolation region,
wherein each first gate structure of the plurality of first gate structures comprises:
a first contact portion and a first end portion disposed on the isolation region, wherein the first end portion is opposite the first contact portion,
a first contact connected to the first contact portion, and
a first gate portion disposed on the first active region; and

wherein a total area of the first contact portion and the first end portion of each first gate structure is substantially equal;
a plurality of second gate structures disposed on the second active region and the isolation region,
wherein each second gate structure of the plurality of second gate structures comprises:
a second contact portion and a second end portion disposed on the isolation region,
a second contact connected to the second contact portion, and
a second gate portion disposed on the second active region,

wherein a total area of the second contact portion and the second end portion of each second grate structure is substantially equal,
wherein a first distance between the first contact and the first gate portion is substantially equal to a second distance between the second contact and the second gate portion, and
wherein a distance of the first gate portion disposed on the first active region is different than a distance of the second gate portion disposed on the second active region; and
a plurality of third gate structures disposed on the third active region and the isolation region, wherein the third gate structure comprises:
a third contact portion disposed on the isolation region;
a third contact connected to the third contact portion, and
a third gate portion disposed on the first active region,

wherein the third gate structure is smaller than the first gate structure, and
wherein the total area of the first portion the first end portion of each first gate structure is substantially equal to a total area of the third contact portion and the third end portion of each third gate structure of the plurality of third gate structures.
