  • Patent number: 11923320
    Abstract: A semiconductor device includes a semiconductor die having a top side surface comprising a semiconductor material including circuitry therein having bond pads connected to nodes in the circuitry, a bottom side surface, and sidewall surfaces between the top side surface and the bottom side surface. A metal coating layer including a bottom side metal layer is over the bottom side surface that extends continuously to a sidewall metal layer on the sidewall surfaces.

  • Patent number: 11183441
    Abstract: The disclosed principles provide a stress buffer layer between an IC die and heat spreader used to dissipate heat from the die. The stress buffer layer comprises distributed pairs of conductive pads and a corresponding set of conductive posts formed on the conductive pads. In one embodiment, the stress buffer layer may comprise conductive pads laterally distributed over non-electrically conducting surfaces of an embedded IC die to thermally conduct heat from the IC die. In addition, such a stress buffer layer may comprise conductive posts laterally distributed and formed directly on each of the conductive pads. Each of the conductive posts thermally conduct heat from respective conductive pads. In addition, each conductive post may have a lateral width less than a lateral width of its corresponding conductive pad. A heat spreader is then formed over the conductive posts which thermally conducts heat from the conductive posts through the heat spreader.
