  • Abstract
    The post-breakdown behaviour of a thin SiO2 layer on the same oxide location under repetitive ramped voltage stress using a conductive atomic force microscopy is reported for the first time. It was observed that the oxide voltage on the same spot decreases and then oscillates between certain smaller values after it is broken down. A mechanism based on permanent trap generation in the oxide accompanied with trap capture radius and trap energy level relaxation is proposed to explain the oxide voltage oscillation phenomenon.
