Patent ID: 8908144

Claim:
A lithographic apparatus, comprising: a support constructed to support a patterning device, the patterning device being capable of imparting a radiation beam with a pattern in its cross-section to form a patterned radiation beam; a substrate table constructed to hold a substrate; a projection system configured to project the patterned radiation beam onto a target portion of the substrate, the projection system being mounted to a reference element of the lithographic apparatus by a resilient mount to reduce a transfer of high frequency vibration from the reference element to the projection system; and a control system to counteract a position error of the substrate table and the support relative to the projection system, wherein the control system comprises an acceleration sensor to provide an acceleration signal representative of an acceleration of the projection system and wherein the control system is configured to derive a support feed-forward signal and a substrate table feed-forward signal from the acceleration signal, the support feed-forward signal to be provided to a support actuator and the substrate table feed-forward signal to be provided to a substrate table actuator.
