    Abstract: The present invention relates to a method for improving adhesion between ceramic and a thick film circuit. The method is particularly directed to accelerate the formation of a ceramic-metal eutectic phase between the ceramic carrier and the metal circuit by solid-phase diffusion bonding under a positive atmosphere. A metallic conductive slurry or its oxide slurry is printed on the surface of the ceramic carrier to form a circuit pattern by a thick film screen printing. The ceramic carrier is placed in an oven with temperature controlled by a program under a positive-pressure atmosphere of an inert gas including nitrogen, hydrogen or their mixtures. An eutectic phase is formed between the ceramic carrier and the metal circuit under a high temperature eutectic condition to increase the adhesion between the ceramic carrier and the thick film circuit.
