20080206682 | Fabrication method of micro-lens and fabrication method of master for micro-lens - A method of fabricating a micro lens, the method including: forming a photo-sensitive film on a substrate; placing a photo mask at a predetermined distance from a top of the photo-sensitive film; exposing the photo-sensitive film by varying an area of exposure of the photo-sensitive film so as to selectively expose three-dimensional structures of the photo-sensitive film corresponding to desired micro lenses; and developing the photo-sensitive film such that the exposed three-dimensional structures remain. Also, there is provided a method of fabricating a master for a micro lens, in which a master material is applied on the photo-sensitive film with the three-dimensional structures to form a master having the three-dimensional structures transferred thereonto. | 08-28-2008 |
20080224160 | High-power light emitting diode and method of manufacturing the same - Provided is a method of manufacturing a high-power LED package, the method including the steps of: preparing a mold having an irregularity pattern; providing a transparent resin solid having an irregularity pattern provided on the surface thereof by using the mold; preparing an irregularity film with the irregularity pattern by cutting a portion of the transparent resin solid; preparing an LED package structure having a cavity in which an LED chip is mounted; filling transparent liquid resin into the cavity having the LED chip mounted therein; mounting the irregularity film on the transparent liquid resin such that the irregularity film projects from the cavity at a predetermined height; and curing the transparent liquid resin having the irregularity film mounted thereon. The irregularity pattern of the irregularity film projects from the cavity at a predetermined height. | 09-18-2008 |
