Claim:
1. A method for manufacturing an LED metal package comprising: forming at least one cavity comprising a concave pit reaching down to a predetermined depth of a metal substrate which is electrically separated by at least one vertical insulation layer, wherein said at least one vertical insulation layer is accommodated at the bottom thereof; shadow masking the entire upper surface of the metal substrate using a mask except a portion of the upper surface of said metal substrate which is formed inside of each of said at least one cavity; removing the oxide layer which is formed on said portion of the upper surface not covered by said shadow masking; depositing an electrode layer on each of said portion of the upper surface where said oxide layer has been removed; removing said mask; bonding an optical device chip on said electrode layer by soldering using a gold-tin (AuSn) alloy soldering layer; and wire bonding an electrode of said optical device located in one side of said metal substrate with respect to each of said vertical insulation layer to a portion of said metal substrate located in the other side of said metal substrate with respect to each of said vertical insulation layer.
