Abstract
A semiconductor device includes first and second p-type diffusion regions, and first and second n-type diffusion regions that are each electrically connected to a common node. Conductive features are each defined within any one gate level channel that is uniquely associated with and defined along one of a number of parallel gate electrode tracks. The conductive features respectively form gate electrodes of first and second PMOS transistor devices, and first and second NMOS transistor devices. The gate electrodes of the first PMOS and second NMOS transistor devices are electrically connected. However, the first PMOS and second NMOS transistor devices are physically separate within the gate electrode level region. The gate electrodes of the second PMOS and first NMOS transistor devices are electrically connected. However, the second PMOS and first NMOS transistor devices are physically separate within the gate electrode level region.
