  • Publication number: 20070262469
    Abstract: A semiconductor package includes a substrate formed of a board material, a semiconductor die bonded to the substrate, and an encapsulant on the die. The package also includes an array of external contacts formed as multi layered metal bumps that include a base layer, a bump layer, and a non-oxidizing outer layer. The external contacts are smaller and more uniform than conventional solder balls, and can be fabricated using low temperature deposition processes, such that package warpage is decreased. Further, the external contacts can be shaped by etching to have generally planar tip portions that facilitate bonding to electrodes of a supporting substrate. Die contacts on the substrate can also be formed as multi layered metal bumps having generally planar tip portions, such that the die can be flip chip mounted to the substrate.

  • Publication number: 20060244141
    Abstract: A package including a package substrate, a die-substrate assembly including a substrate including a plurality of layers including a layer having a mesh to stiffen the substrate adapted to mount one or more dice, one or more dice mounted on the substrate and a molding compound to attach the substrate to the package substrate. Various embodiments include a method comprising providing a substrate including a layer having an outer surface, depositing a metal layer on the outer surface, and etching the metal layer to form an opening, the opening enclosing an area on the outer surface to mount one or more dice.
