Abstract :
This work quantitatively compares breakdown triggers for constant voltage stress of large area NMOS capacitors (up to 10 mm2) with 1.8 to 12 nm gate oxide thickness (with negative VG). We conclude that in the studied range, breakdown is identified more reliably with a current step trigger than through increased current fluctuation (RMS). We also present data filtering algorithms that significantly enhance the ratio between the breakdown signal and background noise level
