Patent ID: 8704226

Claim:
A three-dimensional integrated circuit comprising: a rewiring member that is plate-like; a chip layered on the rewiring member; a plurality of connecting members and a plurality of redundant connecting members both arranged in the chip and configured to electrically connect the rewiring member and the chip; and first and second redundant circuits embedded in the rewiring member and the chip, respectively, and each configured to, when one of the plurality of connecting members is faulty, cause one of the plurality of redundant connecting members to transmit a signal between the rewiring member and the chip, instead of the faulty one of the plurality of connecting members, wherein the plurality of connecting members include first and second subsets that are arranged in first and second regions, respectively, a distance between the rewiring member and the chip exceeds a predetermined threshold value in the first region in contrast to the second region, and the first subset has a higher proportion of connecting members that the first and second redundant circuits can replace with a subset of the plurality of redundant connecting members than the second subset.
