Abstract
A semiconductor device is provided that includes a local passthrough interconnect structure present in a non-active device region of the device. A dielectric fill material structure is located between the local passthrough interconnect structure and a functional gate structure that is present in an active device region that is laterally adjacent to the non-active device region. The semiconductor device has reduced capacitance (and thus circuit speed is not compromised) as compared to an equivalent device in which a metal-containing sacrificial gate structure is used instead of the dielectric fill material structure.
