A multi-chip integrated circuit (IC) apparatus includes a substrate, one or more first IC chips mounted on the substrate, and a second IC chip mounted on the substrate. One or more first heat sinks are respectively thermally coupled to the one or more first IC chips. A second heat sink is thermally coupled to the second IC chip. An under side of the second heat sink is located further from the substrate than each of respective one or more top sides of the one or more first heat sinks.

Heat sink configuration for multi-chip module

An integrated circuit (IC) chip package includes a substrate and a wafer comprising an IC chip arranged on the substrate. The substrate includes first mounting pads unconnected to electrical connections in the substrate. The wafer includes second mounting pads that are disposed around corners of the IC chip, that extend radially outward relative to circuitry in the IC chip, that are unconnected to circuitry in the IC chip, and that mate with the first mounting pads on the substrate, respectively.

IC chip package with dummy solder structure under corner, and related method

An IC chip package includes a substrate having a plurality of interconnect metal pads, and a chip having a plurality of interconnect metal pads arranged thereon. An interconnect solder structure electrically connects each of the plurality of interconnect metal pads. The chip is devoid of the interconnect solder structures and interconnect metal pads at one or more corners of the chip. Rather, a dummy solder structure connects the IC chip to the substrate at each of the one or more corners of the IC chip, and the dummy solder structure is directly under at least one side of the IC chip at the one or more corners of the IC chip. The dummy solder structure has a larger volume than a volume of each of the plurality of interconnect solder structures. The dummy solder structure eliminates a chip-underfill interface at corner(s) of the chip where delamination would occur.
