  • Patent number: 8476746
    Abstract: A leadframe enhancing molding compound bondability includes a chip base and a pin holder. The chip bases includes a chip pad and a support, wherein the chip pad includes a side protrusion extending out of the support, and the side protrusion has a lower surface, and the support has a sidewall, and wherein the lower surface and the sidewall interconnect at an intersection line, and the lower surface is formed upwardly with a recess. Further, a pin holder includes a pin stand and a seat, wherein the pin stand has an edge portion extending out of the seat, the edge portion has a lower surface, the seat has a sidewall, and the lower surface and the sidewall interconnect at a crossing line. The lower surface of the pin stand is formed upward with a recess. As such, the bondability between the leadframe and the molding compound can be greatly enhanced.

  • Patent number: 8035205
    Abstract: A semiconductor package can comprise a die stack attached to a substrate, with bond wires electrically connecting the two. Often multiple die stacks are adhered to a single substrate so that several semiconductor packages can be manufactured at once. A molding compound flow controller is optimally associated with the substrate or semiconductor package at one or more various locations. Flow controllers can control or direct the flow of the molding compound during the encapsulation process. Flow controllers can be sized, shaped, and positioned in order to smooth out the flow of the molding compound, such that the speed of the flow is substantially equivalent over areas of the substrate containing dies and over areas of the substrate without dies. In this manner, defects such as voids in the encapsulation, wire sweeping, and wire shorts can be substantially avoided during encapsulation.
