To ensure the reliability of multi-layer ceramic capacitor (MLCC) while its miniaturization is accelerating, it is necessary to understand the degradation mechanism of BaTiO3 dielectric under high temperature and high electric field. At the first stage of the degradation, oxygen vacancies move towards a cathode side in BaTiO3 dielectric, and electric field concentration is formed near cathode. At the second stage, electric field concentration is formed near cathode and anode by increase in electric current. At the third stage, electric field concentration is formed near anode by further electric current. By using the voltage contrast method in SEM that can be observed at a higher magnification than KFM, it has become possible to measure the potential change of individual particles and grain boundaries near the anode of the degraded MLCC. |
