A potentiometer apparatus and method include a plurality of potentiometer components etched onto a substrate. A conductor layer can be printed and fired upon the substrate and over the array of potentiometer components. Thereafter, a thick film layer can be configured upon the substrate. Each potentiometer component can then be laser trimmed from among the plurality of potentiometer components in order to obtain a proper resistance and linearity for each potentiometer component thereof, thereby forming a potentiometer apparatus from each potentiometer among the potentiometer components. The resulting potentiometer apparatus thus constitutes an advanced thick-film (ATF) potentiometer.
