Abstract
A complementary metal oxide semiconductor (CMOS) device including a substrate including a first active region and a second active region, wherein each of the first active region and second active region of the substrate are separated by from one another by an isolation region. A n-type semiconductor device is present on the first active region of the substrate, in which the n-type semiconductor device includes a first portion of a gate structure. A p-type semiconductor device is present on the second active region of the substrate, in which the p-type semiconductor device includes a second portion of the gate structure. A connecting gate portion provides electrical connectivity between the first portion of the gate structure and the second portion of the gate structure. Electrical contact to the connecting gate portion is over the isolation region, and is not over the first active region and/or the second active region.
