Abstract
Device layouts for integrated circuit devices that include threshold voltage shift induced by placement of alternate work function metals adjacent active gates are disclosed. The device layouts include a single epitaxy for active regions in the device with common source/drain regions among the active region rows in the layouts. Metal gate sections above one or more rows of active regions may be replaced with metal of a different work function in inactive regions of the layout. The different work function metal in the inactive regions will induce threshold voltage shift in adjacent (neighboring) active transistors of the device layouts.
