Abstract
A method for forming a resistor on a roughened surface for use in process fluids employed in the semiconductor-processing industry as part of a clean, particle-free, nonreactive, non-trapping, ultra-pure, thermally tolerant, sealed system. In one arrangement, the method for forming the resistor includes the steps of selecting a coating for the roughened surface from among the group of resistive materials, roughening a surface to promote mechanical adherence of the coating to the selection of a coating comprising resistive material, roughening a surface for promoting mechanical adherence of the resistive material thereto, and electroplating the resistive material onto the roughened surface to provide a uniformly controllable resistance in the coating.
