The adhesion between silver paste film and ceramic substrate was improved by an incorporation of SnO 2 conducting oxide. The SnO 2 incorporated silver paste composite film was prepared by SnO 2 solution pouring into commercial silver paste. The SnO 2 in silver paste film was crystallized through high temperature anneal and the electrical property of the SnO 2 silver paste composite film was improved. A densification of the composite paste was enhanced with crystallized SnO 2 phase after high temperature anneal. The SnO 2 crystalline phase was contributed to electrical conductivity of composite paste due to its semiconducting behavior. After densification, void formation was effectively prevented by SnO 2 phase formation. By the incorporation of conducting oxide solution into commercial silver paste, we could use commercial resin-type silver paste on ceramic substrate.
