Abstract:
A method of forming a high power device module comprisinga) forming a pattern of pad openings completely through the metal support substrate; b) electroplating said support substrate with nickel; c) screen printing a patterned conductive solder ink onto both sides of said support substrate; d) firing said support substrate in nitrogen; e) oxidizing the nickel layer by heating in air; f) applying a glazing layer onto the top of said support substrate; g) mounting a multilayer green tape stack having circuitry on each green tape onto the glazed surface of the support substrate; h) laminating the green tape stack to the patterned support substrate; i) filling the openings in the metal support substrate with a high melt temperature dielectric stabilization paste; and j) firing said module.
