Abstract: An integrated circuit layout is provided. The integrated circuit layout includes one or more first cell rows partially extending across a space arranged for an integrated circuit layout along a first direction. Each of the one or more first cell rows has a first height along a second direction perpendicular to the first direction. The integrated circuit layout includes one or more third cell rows partially extending across the space along the first direction. Each of the one or more third cell rows has a second height along the second direction, the second height different from the first height.

Abstract: A semiconductor devices includes a substrate, a power grid structure, and a through via penetrating the substrate. The power grid structure includes: first and second rails extending along a first direction, a conductive wire, a third rail, a conductive via, and a connecting member. The conductive wire is between the first and second rails, and extends along the first direction. The third rail is below the first rail, the second rail and the conductive wire, and extends along a second direction perpendicular to the first direction. The conductive via is between and electrically couples the conductive wire to the third rail. The connecting member is between and electrically couples the first rail to the conductive wire. The through via extends through the substrate and along a third direction perpendicular to the first direction and the second direction. The through via is disposed on and coupled to the conductive wire.

Abstract: An integrated circuit (IC) device includes a substrate with a power control circuit, front and back side metal layers, and first and second feed through vias (FTVs). The front side metal layer has first and second front side power rails. The back side metal layer has first and second back side power rails. The first FTV extends through the substrate, and couples the first front side power rail to the first back side power rail. The second FTV extends through the substrate, and couples the second front side power rail to the second back side power rail. The power control circuit is coupled to the first and second front side power rails, and is controllable to electrically connect the first front side power rail to the second front side power rail, or electrically disconnect the first front side power rail from the second front side power rail.
