Ong King Hoo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7994647
    Abstract: A method of forming a semiconductor package with smooth edges, and a semiconductor package formed thereby is disclosed. In embodiments, after encapsulation, the semiconductor packages may be at least partially singulated from the panel by making one or more cuts through the panel to define one or more edges of the semiconductor package. The one or more edges may be smoothed by applying a laminate to the edges. The edges receiving the laminate may include any edge between a top and bottom surface of the package.
    Type: Grant

  • Publication number: 20080131998
    Abstract: A low profile semiconductor package is disclosed including at least first and second stacked semiconductor die mounted to a substrate. The first and second semiconductor die are separated by a low profile intermediate adhesive layer in which the wire bond loops from the first semiconductor die are embedded. After the intermediate layer is applied, the second semiconductor die may be stacked on top of the intermediate layer. A dielectric layer may be formed on a back surface of the second semiconductor die. As the back side of the second semiconductor die is an electrical insulator, the intermediate layer need not space the wire bond loops from the second semiconductor die as in the prior art, and the apex of bond wires may come into contact with the dielectric layer. The intermediate layer may thus be made thinner in comparison to conventional stacked semiconductor die configurations.

  • Patent number: 6482680
    Abstract: There is disclosed a flip-chip-type method of assembling semiconductor devices. The proposed invention offer one step encapsulation process to promote adhesion of die to the lead finger and prevent the potential of shorts from developing between the adjacent bumps (13) or lead fingers. Conventional mold compound (15) is used to reduce localized stress causes by coefficient of thermal expansion (CTE) mismatch between the die (11) and substrate, or the lead frame (12). This is particularly favorable in promoting greater mechanical robustness of the semiconductor devices. With one step encapsulation process proposed by the present invention, manufacturing process is made simpler, faster and relatively cheaper.
