PATTERN FORMATION METHOD AND LIQUID DROPLET DISCHARGE APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a pattern formation method and a liquid droplet discharge apparatus with an improvement in shape controllability of patterns formed by the liquid droplets and at the same time maintaining optical properties of laser light to be radiated to the liquid droplets. SOLUTION: An opening/closing mechanism 37 having a cap 39 for opening or closing each radiation port 36 of a laser head 35 is formed in a carriage 28 on which the laser head 35 is loaded. At a time when the closing operation starting position Pc is immediately under a nozzle N, the cap 39 is closed to keep each radiation port 36 closed during the time a liquid F is extradischarged.
