Abstract
Disclosed embodiments herein relate to an integrated circuit including power switches with active regions connected to form a contiguous region. In one aspect, the integrated circuit includes a first layer including a first metal rail extending in a first direction. In one aspect, the integrated circuit includes a second layer above the first layer along a second direction perpendicular to the first direction. The second layer may include active regions for power switches. In one aspect, the active regions of the power switches are connected to form a contiguous region extending in the first direction. The first metal rail may be electrically coupled to the active regions through via contacts. In one aspect, the integrated circuit includes a third layer above the second layer along the second direction. The third layer may include a second metal rail electrically coupled to some of the power switches through additional via contacts.
