摘要:
A system for controlling the focus of a maskless lithographic apparatus is provided, in which a projection system for projecting an image of a programmable patterning device onto a substrate is provided. A first actuator system is configured to move at least one of the lenses of the projection system in a direction perpendicular to the optical axis of the projection system. A radiation beam expander is also provided, that is configured to project an image of the programmable patterning device onto said lens. Furthermore, a second actuator system is provided, configured to move the radiation beam expander in a direction parallel to the optical axis of the projection system in order to control the focus of the image projected onto the substrate.
