    摘要: A seal ring structure of an integrated circuit including a first discontinuous seal wall circumscribing a first portion of the integrated circuit, the first seal wall forming a first pattern on a substrate, and a second discontinuous seal wall circumscribing a second portion of the integrated circuit, the second seal wall forming a second pattern on the substrate and the second portion being at least partially offset from the first portion, wherein the first pattern of the first seal wall interlocks with the second pattern of the second seal wall such that the patterns are interweaved without intersecting, wherein a space is formed between the seal walls, the space creating a non-linear path to the integrated circuit, and wherein the seal ring structure fully circumscribes the integrated circuit. A method of forming such a seal ring structure is also disclosed.

    摘要: A crack stop structure for an integrated circuit (IC) structure is disclosed. The structure can include: a first crack stop pillar laterally separated from a second crack stop pillar within an insulator region of the IC structure. The first crack stop pillar can include an overlapping via in contact with a top surface and at least one side surface of a first conductive element therebelow. The overlapping via of the first crack stop pillar may be in a given layer of the IC structure, and the second crack stop pillar may include a via in the given layer, the via extending to a different depth than the overlapping via. The via of the second crack stop pillar may be an overlapping via in contact with a top surface and at least one side surface of a second conductive element therebelow.

    摘要: An IC chip structure including a plurality of IC chips electrically connected to one another in back-end-of-line (BEOL) interconnect layer of the structure is disclosed. The IC structure may include openings in crack-stop structures surrounding the IC chips and a interconnect wire extending between the IC chips through the openings. A packaging structure for utilizing the IC structure where at least one IC chip is inoperable is also disclosed. The structure may include a first bond pad array on a top surface of a packaging substrate including operable bond pads connected to an operable IC chip and structural support bond pads connected to the inoperable IC chip; a second bond pad array on a bottom surface of the substrate including operable bond pads connected to a single IC chip printed circuit board; and an interconnect structure for connecting the operable bond pads of the first and second bond pad arrays.
