  • Abstract
    The injected charge to recovery (QR) is presented as a parameter to characterize the dielectric breakdown (BD) reversibility in MOSFETs with an ultrathin high- k hafnium-based gate dielectric. The procedure to recover the dielectric is explained, and the dependences of QR on the current limit during BD, the polarity of the BD-recovery stresses, and the number of stress cycles are analyzed.
