Abstract:
1. A semiconductor device, the semiconductor device comprising: a first semiconductor device formed on a first active area in a substrate, the first semiconductor device having a first gate stack comprising a first high-k dielectric layer, a first metal layer and a first semiconductive layer; a second semiconductor device formed on a second active area in the substrate, the second semiconductor device having a second gate stack comprising a second high-k dielectric layer, a second metal layer and a second semiconductive layer; and an electrical connection connecting the first semiconductor device with the second semiconductor device and overlying the first active area, the second active area and a portion of the substrate between the first active area and the second active area, wherein the electrical connection comprises a third high-k dielectric layer and a third metal layer but not a semiconductive layer and wherein the third metal layer is arranged directly over the third high-k dielectric layer.
