Abstract: A method for making resistors includes: forming a protective layer on a metal plate; patterning the metal plate to form a plurality of spaced-apart resistor wires; forming a plurality of bottom parts on the metal plate, each of the bottom parts covering a portion of a respective one of the resistor wires such that the respective resistor wire defines two opposite electrode forming regions; laser-marking the protective layer to form a plurality of identification codes; laser-cutting the protective layer and the metal plate to form a plurality of spaced-apart pre-formed resistors; and forming two terminal electrodes respectively on the two opposite electrode forming regions of each of the resistor wires.
