  • Abstract
    Apparent difference of the dielectric breakdown behavior between high-k stack and the conventional SiO2 is investigated by the temperature dependence of TDDB lifetime. It is clarified that the temperature dependence of TDDB lifetime in high-k stack can be described by two parameters, which is identical to the case of conventional SiO2.
