Abstract: 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.
