A layout of a cell of a semiconductor device is disclosed to include a diffusion level layout including a plurality of diffusion region layout shapes, including a p-type and an n-type diffusion region separated by a central inactive region. The layout of the cell includes a gate electrode level layout corresponding to an entire gate level of the cell. The gate electrode layout includes a number of linear-shaped layout features placed to extend in only a first parallel direction. Each of the number of the linear-shaped layout features within the gate electrode level layout of the restricted layout region is rectangular-shaped. Linear-shaped layout features within the gate electrode level layout extend over one or more of the p-type and/or n-type diffusion regions to form PMOS and NMOS transistor devices. A number of the PMOS transistor devices is equal to a number of the NMOS transistor devices in the cell.
