Abstract :
Enhanced hot-carrier induced current degradation in narrow channel PMOSFET´s with shallow trench isolation structure is observed. This phenomenon is not due to the increase in gate current, but the result of the increase in the electron trapping efficiency of the gate oxide. Mechanical stress may he responsible for the enhanced electron trapping efficiency.
