  • Publication number: 20240088218
    Abstract: Techniques are provided herein to form an integrated circuit having a grating pattern of gate cut structures such that a gate cut structure extends between the gate layers of adjacent semiconductor devices and between the source or drain regions (e.g., epitaxial regions) of the adjacent semiconductor devices. In an example, neighboring semiconductor devices each include a semiconductor region extending between a source region and a drain region, and a gate structure extending over the semiconductor regions of the neighboring semiconductor devices. In some such examples, a gate cut structure is present between each pair of neighboring semiconductor devices thus interrupting the gate structure and isolating the gate electrode of one semiconductor device from the gate electrode of the other semiconductor device. The gate cut structure further extends to separate the source or drain regions of the neighboring semiconductor devices.

  • Patent number: 11557536
    Abstract: Integrated circuit (IC) interconnect lines having improved electromigration resistance. Multi-patterning may be employed to define a first mask pattern. The first mask pattern may be backfilled and further patterned based on 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 material underlying openings defined in the second mask layer that exceed the threshold are removed. First trenches in an underlying dielectric material layer may be etched based on a union of the remainder of the first mask layer and the partially occluded second mask layer. The first trenches may then be backfilled with a first conductive material to form first line segments. Additional trenches in the underlayer may then be etched and backfilled with a second conductive material to form second line segments that are coupled together by the first line segments.
