| 20080197370 | LIGHT EMITTING DIODE STRUCTURE AND MANUFACTURING METHOD THEREOF - A light emitting diode structure has a silicon substrate, a conductive layer, and a light emitting diode. The top surface of the silicon substrate has a cup-structure like paraboloid, and the bottom of the cup-structure has a plurality of through-holes penetrating the silicon substrate. The conductive layer fills up the through-holes and protrudes out from the through-holes. The light emitting diode is disposed on the top of the conductive layer protruding out from the through-holes and is located at the focus of the cup-structure. | 08-21-2008 |

| 20100047942 | METHOD OF MAKING WHITE LED PACKAGE STRUCTURE HAVING A SILICON SUBSTRATE - A method of making a white LED package structure having a silicon substrate comprises providing a silicon substrate and performing an etching process to form a plurality of cup-structures on a top surface of the silicon substrate. Next, a reflective layer on the top surface of the silicon substrate is formed, and a transparent insulating layer on the reflective layer is formed. Subsequently, a plurality of blue LEDs are respectively bonded in each cup-structure, wherein the blue LEDs have various wavelengths. Last, a plurality of kinds of phosphor powders corresponding to the wavelengths of the blue LEDs are mixed with each other and added to a sealing material, and a sealing process is performed to form a phosphor structure on the cup-structures. | 02-25-2010 |
