20080308822 | PACKAGE STRUCTURE OF LIGHT EMITTING DIODE FOR BACKLIGHT - A package structure of a light emitting diode for a backlight comprises a long-wavelength LED die and a short-wavelength LED die. The lights emitted from the two LED dies are mixed with the light emitted from excited fluorescent powders for serving as the backlight of a liquid crystal display. A partition plate is disposed between the two LED dies for separating them from each other. The effective light output of the package structure is increased because each of the two LED dies cannot absorb the light from the other. | 12-18-2008 |
20090022198 | PACKAGE STRUCTURE OF COMPOUND SEMICONDUCTOR DEVICE AND FABRICATING METHOD THEREOF - A package structure of a compound semiconductor device comprises a thin conductive film with a pattern, a die, at least one metal wire or metal bump and a transparent encapsulation material. The die is mounted on the first surface of the thin conductive film, and is electrically connected to the thin conductive film through the metal wire or the metal bump. The transparent encapsulation material is overlaid on the first surface of the conductive film and the die. A second surface of the conductive film is not covered by the transparent encapsulation material, and is opposite the first surface. | 01-22-2009 |
20090029494 | Package structure for solid-state lighting devices and method of fabricating the same - Silicon substrates are applied to the package structure of solid-state lighting devices. Wet etching is performed to both top and bottom surfaces of the silicon substrate to form reflecting cavity and electrode access holes. Materials of the reflecting layer and electrode can be different from each other whose preferred materials can be chosen in accordance with a correspondent function. Formation of the electrode can be patterned by an etching method or a lift-off method. | 01-29-2009 |
20090078956 | PACKAGE STRUCTURE OF PHOTOELECTRONIC DEVICE AND FABRICATING METHOD THEREOF - A package structure for photoelectronic devices comprises a silicon substrate, a first insulating layer, a reflective layer, a second insulating layer, a first conductive layer, a second conductive layer and a die. The silicon substrate has a first surface and a second surface, wherein the first surface is opposed to the second surface. The first surface has a reflective opening, and the second surface has at least two electrode via holes connected to the reflective opening and a recess disposed outside the electrode via holes. The first insulating layer overlays the first surface, the second surface and the recesses. The reflective layer is disposed on the reflective opening. The second insulating layer is disposed on the reflective layer. The first conductive layer is disposed on the surface of the second insulating layer. The second conductive layer is disposed on the surface of the second surface and inside the electrode via holes. The die is fixed inside the reflective opening and electrically connected to the first conductive layer. | 03-26-2009 |
20090121249 | PACKAGE STRUCTURE OF A LIGHT EMITTING DIODE DEVICE AND METHOD OF FABRICATING THE SAME - A package structure for light emitting diode devices comprises a substrate having a reflective cavity, a die mounted inside the reflective cavity, a reflective layer disposed on the surface of the reflective cavity, a plurality of electrodes disposed under the surface of the substrate which is opposite to the reflective cavity, and a dual brightness enhancement film overlaid on the reflective cavity. The dual brightness enhancement film efficiently reflects the polarized light that is generated from the die and is not in a transparent direction back to the reflective layer. Subsequently, this light is reflected from the reflective layer to the dual brightness enhancement film. The portions of the reflected light propagating in the same direction as the transparent direction will transmit through the package structure. | 05-14-2009 |
20090152665 | FABRICATING METHODS OF PHOTOELECTRIC DEVICES AND PACKAGE STRUCTURES THEREOF - The invention discloses a method for fabricating a photoelectric device. A ceramic substrate is first provided, and then a first patterned electrode and a second patterned electrode are formed on and underneath the surface of the ceramic substrate. A plurality of photoelectric devices is sequentially connected to the first electrode layer with a wire solder or a eutectic joint method. The encapsulation materials cover the each photoelectric die to prevent damaged from the external force or environment. Cutting the ceramic substrate along the spaces between the photoelectric dies forms a plurality of independent package units. | 06-18-2009 |
