Abstract:
1. A three-dimensional integrated circuit, comprising: a first interposer comprising through substrate vias (TSV) therein and circuits on a first side of the first interposer; a plurality of first active dies arranged on the first side of the first interposer along a direction parallel to the first side; a plurality of first intermediate interposers, each comprising through substrate vias (TSV), disposed on the first side of the first interposer, wherein each of the plurality of first intermediate interposers is disposed between adjacent first active dies; solder bumps disposed on a second surface of the first interposer opposite to the first side of the first interposer, wherein one of the solder bumps, one of the through substrate vias in the first interposer and one of the through substrate vias in one of the plurality of first intermediate interposers are aligned with each other; and a second interposer comprising through substrate vias (TSV) therein and circuits thereon supported by the first intermediate interposers.
