Classification: CPC G  H | IPC G  H

Claim 7:
8. A lithography system, comprising:
a collector having a mirror surface;
a laser generator aiming at an excitation zone in front of the mirror surface of the collector;
a droplet generator configured to generate droplets along a droplet path;
a droplet deflector operative to apply a sound wave at a position between the droplet generator and the excitation zone;
a first droplet catcher, wherein the excitation zone is between the droplet generator and the first droplet catcher, and the first droplet catcher is not aligned with the droplet generator; and
a second droplet catcher, wherein the excitation zone is between the laser generator and the second droplet catcher, and wherein a shortest distance between the first droplet catcher and the droplet path is less than a shortest distance between the second droplet catcher and the droplet path.
