Stress Induced Leakage Current (SILC) is an increase in the gate leakage current of a MOSFET, due to defects created in the gate oxide during electrical stressing. SILC is perhaps the largest factor inhibiting device miniaturization. Increased leakage is a common failure mode of electronic devices.

Oxide defects[edit]

The most well-studied defects assisting in the leakage current are those produced by charge trapping in the oxide. This model provides a point of attack and has stimulated researchers to develop methods to decrease the rate of charge trapping by mechanisms such as nitrous oxide (N2O) nitridation of the oxide.
