Chucks and clamps for holding objects of a lithographic apparatus and methods for controlling a temperature of an object held by a clamp of a lithographic apparatus

摘要

A lithographic apparatus includes a clamp (406) configured to receive an object (402). The clamp defines at least one channel (408) configured to pass a fluid at a first fluid temperature. The lithographic apparatus also includes a chuck (404) coupled to the clamp. The chuck (404) defines at least one void (464) configured to thermally insulate the chuck from the clamp.
