In this paper we present experimental evidence of the contribution of stress induced traps to Substrate Hot Electron (SHE) injection. We investigate the energy distribution of traps generated by Fowler Nordheim (FN) and Hot Electron (HE) stress with the aid of simulations and experiments. Results suggest that HE stress generates more oxide traps at high energy with respect to FN stress. The comparison between experiments and simulations also provides a new additional evidence of the inelastic nature of the trap assisted tunneling mechanism.

Abstract
In this paper we present experimental evidence of the contribution of stress induced traps to Substrate Hot Electron (SHE) injection. We investigate the energy distribution of traps generated by Fowler Nordheim (FN) and Hot Electron (HE) stress with the aid of simulations and experiments. Results suggest that HE stress generates more oxide traps at high energy with respect to FN stress. The comparison between experiments and simulations also provides a new additional evidence of the inelastic nature of the trap assisted tunneling mechanism.File in questo prodotto:
