  • Patent number: 7667306
    Abstract: A leadframe-based semiconductor package is revealed, primarily comprising a chip, a plurality of leads of a leadframe, a multi-layer tape, and an encapsulant. The multi-layer tape is attached to the chip and includes an adhesive layer disposed on a dielectric core layer. The internal leads of the leads are partially embedded in the adhesive layer in a manner not to directly contact the dielectric core layer. A bonding interface with a U-shaped profile is formed between the adhesive layer and each internal lead to increase the adhesions of the leads so that the internal leads will not be shifted nor delaminated during molding processes. The concentrated stresses exerted on the internal leads disposed at the corners of the packages will be released and reduced.

  • Patent number: 7652383
    Abstract: A semiconductor package module having no solder balls and a method of manufacturing the semiconductor package module are provided. The semiconductor package module includes a module board on which a plurality of semiconductor devices are able to be mounted, a semiconductor package bonded on the module board using an adhesive, being wire-bondable to the module board, and having already undergone an electrical final test, second wires electrically connecting second bond pads of the semiconductor package to bond pads of the module board; and a third sealing resin enclosing the second wires and the semiconductor package. Because the semiconductor package module does not use solder balls, degradation of solder joint reliability (SJR) can be prevented. Further, the use of a semiconductor package that has already undergone an electrical test can reduce degradation of the yield of a completed semiconductor package module.
