Method of repairing an imperfect pattern of metalized portions on a substrate
Abstract
Abstract The method comprises treating a pattern of metalized portions on a substrate which were deposited using a photomasking technique, to render the metal thereon more etch-resistant, then sensitizing and activating at least a part of the treated area on the substrate including an area containing imperfectly formed metalized portions, for autocatalytic deposition of more of the metal, depositing a coating of the metal over the treated area by autocatalytic deposition, defining the portions to be repaired by photomasking and etching techniques preferably using the same mask used to define the original pattern of metalized portions, and etching away unwanted portions of the last-deposited metal without removing any substantial amount of the first-deposited metal portions.
