WIRING FORMING METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a wiring forming method that excels in electrical reliability without generating coffee stains and migrations, which is made possible by rapidly forming a fine wiring using magnetic ink and also by uniformly distributing metallic particles in ink that are discharged. SOLUTION: At the stage of forming a wiring by discharging magnetic ink on the entire surface of a substrate, the magnetic ink is provided in a magnetic field. The magnetic field is provided by a magnetic field forming section located on the other surface of the substrate corresponding to the part where magnetic ink is discharged, and moves according to the movement of an ink-jet head from which the magnetic ink is discharged.
