Lithographic apparatus and device manufacturing method
First Claim
1. A lithographic projection apparatus comprising:
- an illumination system for providing a beam of radiation used to irradiate a patterning device;
a first support that supports the patterning device, the patterning device capable of patterning the beam of radiation;
a second support that supports a substrate;
a projection system for projecting the patterned beam of radiation onto a target portion of the substrate; and
a projection system positioning module that controls at least one of a position and an orientation of the projection system based on at least one of a velocity and an acceleration of the projection system.
