Patent ID: 6852372

Claim:
A fabrication method for an electron source substrate comprises: a measurement step wherein at least one of a substrate having a plurality of pairs of electrodes on the surface thereof, and measurement means for measuring the position of said substrate in at least one direction of the X, Y, and Z directions of the substrate which are mutually orthogonal, is scanned relatively in one direction, thereby measuring the substrate position; a control step for controlling a discharge position of droplets to said substrate from an ink-jet head for discharging droplets containing electroconductive thin-film material, based on the results of said measurement step; and a discharge step for discharging droplets containing electroconductive thin-film material from said ink-jet head to between pairs of electrodes on the surface of said substrate while relatively scanning at least one of said ink-jet head and said substrate in one direction; wherein the scanning direction in said measurement step and the scanning direction in said discharge step are generally parallel; and wherein said measurement step and said discharge step are performed in a single scan.
