Sum Geun Lee 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: 20110180820
    Abstract: Disclosed are a light emitting device and a method of fabricating the same. The light emitting device includes a substrate; first and second light emitting cells, each including a first semiconductor layer, an active layer, and a second semiconductor layer; and a connector located between the first and second light emitting cells and the substrate, to electrically connect the first and second light emitting cells to each other. The connector extends from the second semiconductor layer of the first light emitting cell, across the substrate, and through central regions of the second semiconductor layer and active layer of the second light emitting cells, to contact the first semiconductor layer of the second light emitting cell.
    Type: Application
