  • Patent number: 11854970
    Abstract: Circuit devices, such as integrated circuit devices, are constructed with combination circuits that include two or more cascading transistors, and one or more metal layers disposed over the cascading transistors. The cascading transistors include multiple internal nodes (e.g., common source/drain regions). The multiple internal nodes are not connected to a common metal stripe (the same metal stripe) in the one or more metal layers. The absence of the connections between the internal nodes and a common metal stripe reduce or eliminate the load on the internal nodes. The transistors in the cascading transistors are independent of each other.

  • Patent number: 11830768
    Abstract: Integrated circuit (IC) interconnect lines having line breaks and line bridges within one interconnect level that are based on a single lithographic mask pattern. Multi-patterning may be employed to define a grating structure of a desired pitch in a first mask layer. Breaks and bridges between the grating structures may be derived from a second mask layer through a process-based selective occlusion of openings defined in the second mask layer that are below a threshold minimum lateral width. Portions of the grating structure underlying openings defined in the second mask layer that exceed the threshold minimum lateral width are removed. Trenches in an underlayer may then be etched based on a union of the remainder of the grating structure and the occluded openings in the second mask layer. The trenches may then be backfilled to form the interconnect lines.

The composite dielectric spacer can permit maintaining the real estate of an interface between the conductive interconnect and a trench contact member that has an interface with a carrier-doped epitaxial layer embodying or constituting a source contact region or a drain contact region of a field effect transistor. The trench contact member can form another interface with the conductive interconnect member, providing a satisfactory contact resistance therebetween.
