Abstract: The present disclosure describes various non-planar semiconductor devices, such as fin field-effect transistors (finFETs) to provide an example, having one or more metal rail conductors and various methods for fabricating these non-planar semiconductor devices. In some situations, the one or more metal rail conductors can be electrically connected to gate, source, and/or drain regions of these various non-planar semiconductor devices. In these situations, the one or more metal rail conductors can be utilized to electrically connect the gate, the source, and/or the drain regions of various non-planar semiconductor devices to other gate, source, and/or drain regions of various non-planar semiconductor devices and/or other semiconductor devices. However, in other situations, the one or more metal rail conductors can be isolated from the gate, the source, and/or the drain regions these various non-planar semiconductor devices. This isolation prevents electrical connection between the one or more metal rail conductors and the gate, the source, and/or the drain regions these various non-planar semiconductor devices.

Abstract: A method of manufacturing a semiconductor device includes forming a plurality of fin structures extending in a first direction over a semiconductor substrate. Each fin structure includes a first region proximate to the semiconductor substrate and a second region distal to the semiconductor substrate. An electrically conductive layer is formed between the first regions of a first adjacent pair of fin structures. A gate electrode structure is formed extending in a second direction substantially perpendicular to the first direction over the fin structure second region, and a metallization layer including at least one conductive line is formed over the gate electrode structure.

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.
