Shih-Chen Wei 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: 7675077
    Abstract: A light-emitting diode (LED) and a method for manufacturing the same are described. The light-emitting diode comprises: a conductive substrate including a first surface and a second surface opposite to the first surface; a metal bonding layer deposed on the first surface of the conductive substrate; a reflective metal layer deposed on the metal bonding layer; an N-type semiconductor layer deposed on the reflective metal layer; an active layer deposed on the N-type semiconductor layer; a P-type semiconductor layer deposed on the active layer; a window layer deposed on the P-type semiconductor layer, wherein a thickness of the window layer is substantially at least 50 ?m, and the window layer is composed of a transparent conductive material; and a P-type electrode deposed on the window layer.
    Type: Grant

  • Patent number: 6847046
    Abstract: A light-emitting device and a method for manufacturing the same are described, by forming a SiN/Al1-x-yInxGayN(0?x?1, 0?y?1, x+y?1) superlattice layer between a substrate and an undoped GaN as a buffer layer, so as to reduce dislocation density of the buffer layer. In the SiN/Al1-x-yInxGayN(0?x?1, 0?y?1, x+y?1) superlattice layer, Al1-x-yInxGayN(0?x?1, 0?y?1, x+y?1) can be n-type, p-type or undoped.
