Classification: CPC G  H | IPC G  H

Claim 0:
1. 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;
a droplet deflector operative to apply a force at a position between the droplet generator and the excitation zone, wherein the droplet deflector is a sound wave generator; and
a first droplet catcher in front of the mirror surface of the collector, wherein a distance between the first droplet catcher and the collector along a first direction parallel to an optical axis of the collector is greater than a distance between the excitation zone and the collector along the first direction, and wherein a distance between the first droplet catcher and the droplet generator along a second direction perpendicular to the first direction is less than a distance between the excitation zone and the droplet generator along the second direction.
