Patent ID: 6977713

Claim:
A lithographic apparatus, comprising: an illumination system constructed to provide a beam of radiation; a support structure constructed to support a patterning device, said patterning device serving to impart a cross-section of said beam with a pattern to form a patterned beam of radiation; a substrate table for holding a substrate; a projection system that projects said patterned beam onto a target portion of said substrate; a reference frame, with a position sensor and said substrate being located on said reference frame; a heat transport system having a heating element in thermal interaction with at least one of said projection system and said reference frame for heat transport to or from at least one of said projection system and said reference frame; and a further frame on which said reference frame is mounted, wherein said further frame is provided with a vibration isolation system having a vibration damper adapted to prevent vibrations in said further frame from affecting said reference frame, and said heat transport system being coupled to said further frame.
