  • Patent number: 9024351
    Abstract: A semiconductor light-emitting structure including a first conductive type semiconductor layer, a second conductive type semiconductor layer, a light-emitting layer, an electrode, an insulating layer, and an adhesive layer is provided. The light-emitting layer is disposed between the first conductive type semiconductor layer and the second conductive type semiconductor layer. The electrode is disposed on the first conductive type semiconductor layer. The insulating layer covers a part of the first conductive type semiconductor layer and the electrode. The adhesive layer is disposed between the electrode and the insulating layer so as to bond the electrode and the insulating layer.
    Type: Grant

  • Publication number: 20060255377
    Abstract: A field effect transistor (FET) with novel field-plate structure relates to a Schottky gate FET structure with field plate thereon for increasing the operation voltage. The structure can eliminate surface damages of unpassivated region and degradation of the interface property of gate contacts during plasma etching of dielectric film for gate recesses, and can be reliably used in wireless and satellite communications.
