Description	The noise spectroscopy and third harmonic measurements were used to investigate effect of the contact electrode material on the thick film resistor quality and reliability. Strong dependence of nonlinearity on the contact electrode material wasobserved. Thick film resistors with AgPd contactelectrode have higher value of third harmonic voltage,but show better long term stability and reliabilitycomparing with resistors with Ag contact electrode.From the SEM figures we determined, that the sharpness of AggPd contact electrode is approximately 7deg, while Ag contact electrode sharpness is approx. 12deg. It was proved experimentally that noise spectraldensity is proportional to electric field intensity, whilethird harmonic voltage depends on the third power ofelectric field intensity or current density. Modelling ofthe current distribution for two different shapes of metallic contact cross sections was performed. The model shows that the electrode geometry plays dominant role for current distribution in t The noise spectroscopy and third harmonic measurements were used to investigate effect of the contact electrode material on the thick film resistor quality and reliability.
