ABSTRACT:
An automatic method to repair circuit shorts and near-shorts present in narrow bridges or remnants of bridges between circuit lines. By applying a voltage across a pair of lines, certain electrical phenomena take place at the area of the short or near-short. The electrical phenomena thus generated induce a localized etching in either a gas-phase or liquid-phase medium depending upon which embodiment is used.
