Abstract:
An enhanced heat dissipating chip scale package device, comprising:a heat dissipating base having a guarding wall bounding a recess therein;a chip having an integrated circuit layout on a first side surface thereof, the chip being mounted in the recess by means of an adhesive, the first side surface facing outwardly from the recess, the chip further having a plurality of Al pads on the first side surface and disposed around a periphery of and connected to the integrated circuit;a substrate having at least one metallic circuit layer coupled to the integrated circuit layout of the chip, the substrate being adhered to the first side surface of the chip, the substrate being smaller than the chip such that the Al pads on the chip are not covered by the substrate;a non-conductive resin located in the recess within the guarding wall and covering only edge portions of the substrate and the chip where said metallic circuit layer of the substrate and integrated circuit layout of the chip are coupled, a surface portion of the substrate facing away from the chip being uncovered by the resin; and,a plurality of metal balls disposed on the uncovered surface portion of the substrate at a side remote from the chip for coupling with the metallic circuit layer of the substrate.
