Patents by Inventor Angel Orabuena Alvarez

Angel Orabuena Alvarez 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: 8154111
    Abstract: A semiconductor package that can fit semiconductor chips of various sizes without having to change the footprint of the carrier package. One aspect of the semiconductor package comprises a leadframe, a semiconductor chip attached to the leadframe, electrical connectors electrically connecting the semiconductor chip to the leadframe, and a sealing material. The leadframe has a plurality of leads, with each one of the plurality of leads having an upper side, a lower exposed side, and a laterally exposed side. The upper side of each one of the plurality of leads defines a generally co-planar surface. Further, after sealing material encapsulates the components of the semiconductor package in a spatial relationship, the lower exposed side and the lateral exposed side of the plurality of leads are exposed to the outside surface of the semiconductor package.
    Type: Grant

  • Patent number: 7045396
    Abstract: Leadframe-type semiconductor packages that allow the semiconductor packages to be stacked on top of each other. One aspect of the semiconductor package includes a leadframe, a plurality of electrical connectors, a semiconductor chip, and a sealing material for encapsulating the above components. The leadframe has a plurality of leads, with each one of the plurality of leads running from the top of the semiconductor package to the bottom of the semiconductor package. Each one of the plurality of leads has a top portion protruding from the top surface of the semiconductor package and a bottom portion protruding from the top surface of the semiconductor package and a bottom portion protruding from the bottom surface of the semiconductor package. The leads allow for electrical connection of a second semiconductor package placed on top of the first semiconductor package. Further, the protruding parts of the leads form a space between the stacked semiconductor packages for improved heat dissipation.
