Abstract
A semiconductor device includes first and second FETs including first and second channel regions, respectively. The first and second FETs include first and second gate structures, respectively. The first and second gate structures include first and second gate dielectric layers formed over the first and second channel regions and first and second gate electrode layers formed over the first and second gate dielectric layers. The first and second gate structures are aligned along a first direction. The first gate structure and the second gate structure are separated by a separation plug made of an insulating material. A width of the separation plug in a second direction perpendicular to the first direction is smaller than a width of the first gate structure in the second direction, when viewed in plan view.
