Patents by Inventor Chyi Shyuan Chem

Chyi Shyuan Chem 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).

  • Publication number: 20130230935
    Abstract: An apparatus includes a wafer with a number of openings therein. For each opening, an LED device is coupled to a conductive carrier and the wafer in a manner so that each of the coupled LED device and a portion of the conductive carrier at least partially fill the opening. A method of fabricating an LED device includes forming a number of openings in a wafer. The method also includes coupling light-emitting diode (LED) devices to conductive carriers. The LED devices with conductive carriers at least partially fill each of the openings.

  • Patent number: 8236584
    Abstract: The present disclosure provides one embodiment of a method for fabricating a light emitting diode (LED) package. The method includes forming a plurality of through silicon vias (TSVs) on a silicon substrate; depositing a dielectric layer over a first side and a second side of the silicon substrate and over sidewall surfaces of the TSVs; forming a metal layer patterned over the dielectric layer on the first side and the second side of the silicon substrate and further filling the TSVs; and forming a plurality of highly reflective bonding pads over the metal layer on the second side of the silicon substrate for LED bonding and wire bonding.
