Methods for abutting two cells with different sized diffusion regions and the resulting devices are provided. Embodiments include abutting a first cell having first drain and source diffusion regions and a second cell having second drain and source diffusion regions, larger than the first diffusion regions, by: forming a dummy gate at a boundary between the two cells; forming a continuous drain diffusion region having an upper portion crossing the dummy gate and encompassing the entire first drain diffusion region and part of the second drain diffusion region and having a lower portion beginning over the dummy gate and encompassing a remainder of the second drain diffusion region; forming a continuous source diffusion region that is the mirror image of the continuous drain diffusion region; and forming a poly-cut mask over the dummy gate between, but separated from, the continuous drain and source diffusion regions.

Abstract:
A method includes electrically connecting a plurality of cells of a standard cell library to a power rail. A contact area is deposited to connect a first active area and a second active area of a cell of a plurality cells. The first area and the second area are located on opposite sides of the rail and electrically connected to different drains. The contact area is electrically connected to the power rail using a via. The contact area is masked to remove a portion of the contact area to electrically separate the first active are from the second active area.
