Abstract: The present invention relates generally to a new structure and a method for repairing semiconductor substrates, and more particularly, the invention encompasses a structure and a method for repairing Printed Circuit Boards or other electronic substrates by providing electrical lines on the defective board. On a substrate that has an open or an electrical discontinuity, after the discontinuity has been established, a portion of the electrical line across from the electrical discontinuity are exposed and one or more trenches or grooves are made between the two or more exposed portions of the electrical line. The two exposed portions of the exposed electrical line is then joined by either an electrical wire that is routed through the trench or using a standard deposition process one or more metals or material are deposited in the open trench to provide or restore electrical continuity and the excess deposition material is removed.
