Patent ID: 6992274

Claim:
A laser processing apparatus for irradiating a mask with a plurality of openings formed therein with a pulse laser, and irradiating a plurality of portions of a work to be processed with said pulse laser transmitted through said plurality of openings at the same time, said apparatus comprising: a laser device which outputs said pulse laser; a moving section which moves said mask and said work with respect to each other; and a controller which controls said moving section to move said mask and said work with respect to each other, and controls said laser device to emit said pulse laser a plurality of times, wherein said controller controls said moving section to move said mask and said work with respect to each other so that respective laser irradiated regions disposed adjacent to one another are irradiated with said pulse laser transmitted through said openings different from one another among said plurality of openings, and boundaries of said laser irradiated regions disposed adjacent to each other contact at least each other.
