  • Publication number: 20220270909
    Abstract: A method for assembling at least one stacked substrate package, each stacked substrate package includes binding a laminated base substrate, configured to route interconnections between circuitry on a first surface of the laminated base substrate and circuitry on a second surface of the laminated base substrate, to a surface of a rigid carrier to prevent warping of the laminated base substrate. Each base substrate is coupled to at least one dielectric build-up substrate, which is configured to route integrated interconnections between a top surface and a bottom surface of the dielectric build-up substrate, to the laminated base substrate. At least one integrated circuit die is coupled to the at least one dielectric build-up substrate, and then the carrier is released from the laminated base substrate to form an assembled stacked substrate package. Also, multiple stacked substrate packages may be assembled in parallel on one carrier.

  • Patent number: 11171104
    Abstract: 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.

  • Patent number: 11049819
    Abstract: Package assemblies including a die stack and related methods of use. The package assembly includes a substrate with a first surface, a second surface, and a third surface bordering a through-hole extending from the first surface to the second surface. The assembly further includes a die stack, a conductive layer, and a lid. The die stack includes a chip positioned inside the through-hole in the substrate. A section of the conductive layer is disposed on the third surface of the substrate. A portion of the lid is disposed between the first chip and the section of the conductive layer. The conductive layer is configured to be coupled with power, and the lid is configured to be coupled with ground. The portion of the lid may act as a first plate of a capacitor, and the section of the conductive layer may act as a second plate of the capacitor.
