    Abstract: The present disclosure describes an apparatus with a local interconnect structure. The apparatus can include a first transistor, a second transistor, a first interconnect structure, a second interconnect structure, and a third interconnect structure. The local interconnect structure can be coupled to gate terminals of the first and second transistors and routed at a same interconnect level as reference metal lines coupled to ground and a power supply voltage. The first interconnect structure can be coupled to a source/drain terminal of the first transistor and routed above the local interconnect structure. The second interconnect structure can be coupled to a source/drain terminal of the second transistor and routed above the local interconnect structure. The third interconnect structure can be routed above the local interconnect structure and at a same interconnect level as the first and second interconnect structures.
