Abstract:
1. A method for fabricating a chip resistor device, comprising the steps of: (a) defining a plurality of substrates on an insulating film by a plurality of spaced-apart and interlaced splitting grooves, each of the splitting grooves having a depth shorter than a thickness of the insulating film, each of the substrates having a first surface and a second surface opposite to the first surface, the first surface having two opposite edges and two electrode forming regions adjacent to the two opposite edges respectively; (b) forming two indented patterns respectively in the electrode forming regions of the first surface of each of the substrates, the indented patterns being indented from the first surface; (c) filling a first pasty conductive material into the two indented patterns so as to form two contact electrode growing films on the indented patterns of each of the substrates; (d) forming a resistor made of a second pasty conductive material on the first surface of each of the substrates between the two contact electrode growing films, the resistor having two opposite ends electrically contacting the contact electrode growing films; (e) cutting the insulating film along the splitting grooves; and (f) coating the contact electrode growing films of each of the substrates with a conductive material so as to respectively form two electrodes on the electrode forming regions of each of the substrates.
