Abstract:
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.

Abstract:
A method of manufacturing an optical device for a back light unit includes forming a metal ingot by adhering insulating layers between metal plates. The metal ingot is cut in a vertical direction to create original substrates each with insulating layer portions in parallel with intervals therebetween. Solder resist is deposited on at least one of a top surface and bottom surface of an original substrate.

Abstract:
A chip substrate includes: a conductive layer being stacked in one direction and constituting a chip substrate; an insulator being alternately stacked with the conductive layer and electrically separating the conductive layer; and a lens insert having: a depression reaching down to a predetermined depth from a specified area of an upper surface of the chip substrate overlapping with the insulator; and a predetermined number of sides on the upper surface wherein arcs are formed at regions where the sides are met with each other. Since the space for inserting a lens can be formed to have a shape comprising straight lines, and a lens to be inserted can also be manufactured in a shape comprising straight lines, therefore the manufacturing process for a lens to be inserted into the chip substrate can be further simplified.
