Abstract
A method of manufacturing a light emitting device (LED) package includes forming a reflector using nano-imprinting to increase an intensity of light extracted toward an external environment by increasing an angle of a reflector.
Claims15
A method of manufacturing a light emitting device (LED) package, the method comprising:
- mounting an LED chip on a substrate;
- coating an insulating layer on the substrate;
- pressing the insulating layer with a first stamp having a patterned surface;
- etching the pressed insulating layer to expose a portion of the LED chip;
- depositing a metallic layer that connects the exposed LED chip and the substrate;
- forming an electrode by removing the insulating layer;
- spraying, on the substrate, a reflector material;
- pressing the sprayed reflector material with a second stamp having a patterned surface, using nano imprinting;
- forming a reflector to have a pattern corresponding to the patterned surface of the second stamp by etching the pressed reflector material to expose the LED chip;
- and
- forming a phosphor layer on the LED chip.
