MULTILAYER CERAMIC CAPACITOR AND PROCESS FOR PRODUCING SAME

摘要

Diffusion-phase grain layer formed of diffusion-phase grains (first grains G 1 and second grains G 2 ) arranged in the form of a layer is present between a dielectric layer and an internal electrode layer. Thus, even if oxygen vacancies formed in third grains G 3 constituting the dielectric layer move toward the interface between the dielectric layer and the internal electrode layer to accumulate in the third grains G 3 present in the vicinity of the interface, the presence of the diffusion-phase grain layer prevents a current from concentrating in a portion having a reduced resistance due to the oxygen vacancies to suppress insulation degradation that can be formed in the multilayer ceramic capacitor.
