Abstract

A method of forming an active contact-gate contact interconnect including forming a first gate contact to a first gate electrode in an active region in a substrate, forming a first active contact to another portion of the first active region. The first gate contact and the first active contact include an approximately equal surface area, and forming an interconnect between the first active contact and the first gate contact. The interconnect includes a first metal wire in a first metal layer electrically connecting the first active contact to the first gate contact. The method may also include forming a second metal wire in the first metal layer configured to electrically connect a third metal wire in a second metal layer to an external contact to a second active region in the substrate, the external contact including the approximately equal surface area.
