ABSTRACT:
A prepatterned potentiometer precursor includes a precursor substrate; and at least two spaced apart potentiometer precursor patterns on the substrate, each potentiometer precursor pattern including a bridge, two substantially similar end taps transverse to and extending from the bridge, and a center tap transverse to and extending from the bridge and centrally disposed between the end taps wherein the center taps of the bridges are substantially parallel to each other and are substantially wider than the end taps. A method of determining the distance between test features of test patterns on a test piece includes preparing a precursor substrate including at least two electrically conducting spaced apart potentiometer precursor patterns, each potentiometer precursor pattern including a bridge, two substantially similar end taps transverse to and extending from the bridge, and a center tap transverse to and extending from the bridge and centrally disposed between the end taps.
