Abstract :
MOS capacitors with TiSi2 gate electrode show electron trapping, interface state generation upon electron injection and reduction of breakdown strength; these effects become more pronounced for electrodes with increasing thickness. Evidence is presented that this degradation of the insulator is due to mechanical stress in the MOS system caused by the gate.
