Tsai-Chen SUNG 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: 12119427
    Abstract: The light emitting device includes a growth substrate, a light-emitting semiconductor structure, conductive pillars, an insulating layer, and first and second electrodes. The light-emitting semiconductor structure includes a first-type semiconductor layer, a light-emitting layer and a second-type semiconductor layer disposed on the growth substrate from top to bottom. The conductive pillars are disposed in the light-emitting semiconductor structure. The conductive pillars penetrates is in contact with the second-type semiconductor layer and electrically connected to the substrate. A first portion of the insulating layer is disposed between the first-type semiconductor layer and the substrate, and a second portion of the insulating layer electrically insulates the first-type semiconductor layer and the light emitting-layer from the conductive pillars. The first electrode is electrically connected to the first-type semiconductor layer and electrically insulated from the conductive pillars.
