Influence of HVP trimming on primary parameters of thick resistive films



The revival of thick-film technology can be attributed to increasing use of ceramic MEMS devices. Thick-film resistors that are being used both as sensing and as resistive elements are facing reduction in dimensions, higher required tolerances and increasing use of buried components. For these reasons standard trimming procedures are being replaced by an alternative method—trimming by energy of high-voltage pulses (HVP trimming). Aim of this paper is to determine primary geometrical, physical and technological parameters responsible for resistance and noise index changes in thick resistive films caused by this alternative trimming method. Both theoretical and experimental considerations are taken into account using three groups of resistors based on commercially available 1, 10 and 100 kΩ/sq thick-film resistor compositions that were subjected to a series of pulses with increasing amplitudes in such a manner that resistance values gradually changed. Possible causes of observed micro and macro structural changes are determined using presented evaluation method resulting in defining primary parameters responsible for reported behavior.
