METHOD FOR FABRICATING MULTILAYER CERAMIC ELECTRONIC COMPONENT AND MULTILAYER CERAMIC ELECTRONIC COMPONENT

摘要

In a multilayer ceramic capacitor, its internal electrode formed by a thin-film formation method tends to bead up as a result of a calcination process. When forming a metal thin film (22) to be an internal electrode (13) on a ceramic green sheet (21), first metal grains (23) consisting of a first metal such as nickel are mixed with second metal grains (24) more oxidizable than the first metal grains and consisting of a second metal such as chrome. In the calcinations process, the second metal grains (24) in the vicinity of the interface between the metal thin film (22) and the ceramic green sheet (21) are selectively oxidized, and the second metal grains inside the metal thin film are deposited outside of the metal thin film and oxidized, so that an oxide layer (27) including the oxidized second metal grains is formed along the interface. The first metal grains are then sintered while growing the first metal grains along the oxide layer, thereby forming the internal electrode.
