Random telegraph signal after soft-breakdown is explained by the capture-emission of electrons in the same oxide traps of the soft-breakdown path. It is shown that not only the gate current noise, but also the substrate current noise largely increase at the soft-breakdown moment in n-channel metal-oxide-semiconductor field effect transistor (nMOSFET) stressed with positive gate polarity. A strong correlation of the noise in the gate and substrate current is reported.

Abstract
Random telegraph signal after soft-breakdown is explained by the capture-emission of electrons in the same oxide traps of the soft-breakdown path. It is shown that not only the gate current noise, but also the substrate current noise largely increase at the soft-breakdown moment in n-channel metal-oxide-semiconductor field effect transistor (nMOSFET) stressed with positive gate polarity. A strong correlation of the noise in the gate and substrate current is reported.File in questo prodotto:
