Abstract

The adhesion between silver paste film and ceramic substrate was improved by an incorporation of SnO2 conducting oxide. The SnO2 incorporated silver paste composite film was prepared by SnO2 solution pouring into commercial silver paste. The SnO2 in silver paste film was crystallized through high temperature anneal and the electrical property of the SnO2silver paste composite film was improved. A densification of the composite paste was enhanced with crystallized SnO 2 phase after high temperature anneal. The SnO2 crystalline phase was contributed to electrical conductivity of composite paste due to its semiconducting behavior. After densification, void formation was effectively prevented by SnO2 phase formation. By the incorporation of conducting oxide solution into commercial silver paste, we could use commercial resin-type silver paste on ceramic substrate.
