ABSTRACT:
A new method of repairing partially defective conductor lines is disclosed. The defective site comprising narrow necks or thin portions or cracks in a conductor line is heated by passing a relatively high current. Using the thermobattery principle in an electroplating process or an electroless plating process or a pyrolytic deposition process, a conductive material is deposited at the defective site, and the partially defective conductor line is thereby repaired. A method of repairing gaps and circuit opens in a conductor line is also disclosed.
