Abstract:
1. A fabrication method of a light emitting diode package comprising steps of: preparing a submount substrate formed of a first silicon layer, a first insulation layer, a second silicon layer, and a second insulation layer deposited in their order; selectively etching the first silicon layer to form a groove exposing the first insulation layer in an area corresponding to a mounting area of an LED; forming a lower metal layer on the exposed surface of the first insulation layer and a lower surface of the first silicon layer to fill up the groove; forming a package electrode pattern on the second insulation layer, and mounting the LED on the package electrode pattern by flip-chip bonding; providing a spacer having a cavity on the package electrode pattern to receive the LED in the cavity; and adhering an optical element to the upper surface of the spacer.
