Patents by Inventor David Justin West

David Justin West 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: 9818653
    Abstract: A first package includes a laminate layer, an overmold layer above and in direct contact with the laminate layer, and a logic circuit-through-silicon via (TSV) layer including a first logic die and TSVs. The logic circuit-TSV layer is within the overmold layer, and the TSVs are electrically exposed at a top surface of the overmold layer. The first package may be fabricated and tested by a first party prior to being provided to a second party. A second package includes a second logic die. The second party may attach the second package to the first package at the electrically exposed TSVs of the first package to realize a complete and functional semiconductor device.
    Type: Grant

  • Patent number: 9433105
    Abstract: An electrically insulating substrate is provided. The electrically insulating substrate includes a set of areas to be formed into a set of printed circuit boards. Each of the set of areas is separated from others of the set of areas by a dicing channel. A set of signal wiring conductors is fabricated onto the set of areas of the electrically insulating substrate so that at least one of the set of signal wiring conductors terminates proximate to the dicing channel. A set of plated through holes is fabricated through at least one of the set of areas such that at least one of the set of plated through holes connects to at least one of the set of signal wiring conductors. The electrically insulating substrate is singulated along a set of singulation lines to form the set of printed circuit boards. The singulation lines intersect with the plated through holes, so that a portion of the plated through holes is exposed along the peripheral edge of the resulting printed circuit boards.

  • Patent number: 8530345
    Abstract: An electronic apparatus and method of fabrication of the apparatus, the apparatus including a first electronic device having an interconnection surface with a first plurality of interconnection pads extending from the surface by a first distance and a second plurality of alignment posts extending from the surface by a second distance greater than the first distance, and a second electrical device having an interconnection surface with a first plurality of electrical interconnection pads, each pad arranged to contact a corresponding first electronic device interconnection surface pad upon assembly of the first electronic device interconnection surface upon the second electronic device interconnection surface, the second electronic device interconnection surface including a third plurality of alignment posts, each located to be adjacent to at least one of the first electronic device alignment posts upon assembly.
