Abstract:
1. A method for making chip resistor components, comprising: (a) forming a plurality of intersecting strip-like first and second notches in a dielectric substrate so as to form a plurality of resistor-forming strips separated by the first notches; (b) forming a pair of spaced apart strip-like upper electrodes on an upper surface of each of the resistor-forming strips, and a pair of spaced apart strip-like lower electrodes on a lower surface of each of the resistor-forming strips, the upper and lower electrodes being substantially parallel to the first notches; (c) forming a strip-like resistor film on the lower surface of each of the resistor-forming strips such that the resistor film extends between and is brought into contact with the lower electrodes; (d) forming a strip-like insulator layer on the resistor film; (e) forming a hole pattern in the insulator layer and the resistor film; (f) forming a strip-like insulating shield layer on the insulator layer; (g) cleaving the dielectric substrate along the first notches so as to form a plurality of strip-like semi-finished products; (h) forming a pair of strip-like side electrodes on two opposite sides of each of the semi-finished products such that each of the side electrodes extends between and is brought into contact with an adjacent one of the upper electrodes and an adjacent one of the lower electrodes; and (i) cleaving each of the semi-finished products along the second notches so as to form a plurality of resistor blanks.
