Original Abstract

We investigate the effect of silver diffusion and migration from contact electrode into thick film resistive layer and its influence on resistor stability. Silver diffusion results to the resistive layer conductivity increase in the vicinity of contact. This leads to effective shortening of thick film resistor length and lowering of the electric field intensity near the contact. The noise spectroscopy and third harmonic measurements were used to investigate this effect. Numerical model of current density and electric field distribution was performed to estimate the influence of silver diffusion and migration.
