Abstract:
A reticle stage is provided, including an electrostatic chuck and an acoustic wave transducer. The electrostatic chuck includes multiple chucking electrodes embedded in a dielectric body and configured to secure a reticle to a chuck surface of the dielectric body by electrostatic attraction. The acoustic wave transducer is disposed on the chuck surface and configured to impart a surface acoustic wave to the chuck surface to vibrate the chuck surface, thereby removing the reticle from the reticle stage.

Claim (Index 1):
A reticle stage, comprising:\n an electrostatic chuck comprising a plurality of chucking electrodes embedded in a dielectric body, wherein the electrostatic chuck is configured to secure a reticle to a chuck surface of the dielectric body by electrostatic attraction, wherein the electrostatic chuck further comprises a plurality of protruding burls formed on the chuck surface and in a central region of the chuck surface to support the reticle; and an acoustic wave transducer disposed on the chuck surface and configured to impart a surface acoustic wave to the chuck surface to vibrate the chuck surface, thereby removing the reticle from the reticle stage, wherein the acoustic wave transducer is configured to pass through the central region.
