CONDUCTIVE-MATERIAL-CONTAINED LIQUID FOR REPAIRING WIRING ON ELECTRONIC CIRCUIT SUBSTRATE, AND METHOD OF REPAIRING WIRING ON ELECTRONIC CIRCUIT SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To repaire wiring by appropriately coating a conductive-material-contained liquid on the broken portion of the wiring on an electronic circuit substrate irrespective of a coating method of a solution coater, and thereby forming a conductive thin film having appropriate thickness.;SOLUTION: Holes 4a, 4b for coupling of repair wiring are provided at a preselected repair part of a wiring broken portion 3a in TFT wiring (wiring) 3 formed on a TFT substrate (electronic circuit substrate) 1 by irradiating pulse laser La using a laser processor 6, and then a conductive-material-contained liquid 8 is coated with such composition as comprising a solvent including a highly volatile solvent and a lowly volatile solvent, which contains a conductive material. After the highly volatile solvent in the liquid 8 volatilizes, continuous wave laser is irradiated to a portion where the conductive-material-contained liquid has been coated to heat the liquid 8, thereby percipitating a conductive thin film of the conductive material in the preselected repair part, and thereby repairing connection of the wiring broken portion 3a.;COPYRIGHT: (C)2006,JPO&NCIPI
