发明名称 LED METAL SUBSTRATE PACKAGE AND METHOD OF MANUFACTURING SAME
摘要 The present invention relates to an LED metal substrate package, and particularly, to an LED metal substrate package having a heat dissipating structure, and a method of manufacturing same. The method comprises at least the steps of: forming at least one cavity having a groove of a predetermined depth in a metal substrate that is electrically separated by at least one vertical insulation layer, the cavity having one vertical insulation layer built in a floor thereof; treating all surfaces, except portions of the top surface of the metal substrate formed in the respective cavities, with shadow masking; removing an oxide film formed on the surface portions that have not been treated with masking; depositing an electrode layer on each of the surface portions of the oxide layer that have been removed; removing the shadow mask; performing Au/Sn soldering on the electrode layer and bonding an optical device chip; and wire bonding one electrode of the optical device, disposed on one side of the metal substrate with respect to each of the vertical insulation layers, through wires to the metal substrate disposed on the other side of each of the vertical insulation layers. The present invention forms solder using Au/Sn material, which has good heat dissipating characteristics and good bonding characteristics, on the electrode layer to bond an optical device chip, so as to have excellent heat dissipating performance compared to existing LED metal packages that use Ag epoxy.
