In this paper we have investigated the long-term reliability of TiN/HfSixOy/TiN Metal-Insulator-Metal (MIM) capacitors by using constant voltage stress (CVS) and constant current stress (CCS). No significant increase in leakage current was observed as a function of stress time. On the other hand, stress induced capacitance changes were observed due to change in quadratic and liner coefficients of permittivity nonlinearities. Stress-induced oxygen vacancy related defect formation believed to be the cause of this shift in permittivity.
