Abstract
Steering system for a droplet generator in a EUV system. The steering system permits controlled positioning of a droplet release point of the droplet generator. A movable member holding the droplet generator is coupled to stationary elements of the EUV system through a coupling system having a first subsystem that constrains lateral translation of the movable member, and a second subsystem that controls a relative inclination of the movable member. The first and second subsystems preferably include one or a combination of flexures that permit highly precise and repeatable positioning.
