Abstract: A lithographic apparatus is provided. The lithographic apparatus includes a reticle and an electrostatic clamp configured to releasably hold the reticle. The electrostatic clamp includes a first substrate having opposing first and second surfaces, a plurality of burls located on the first surface and configured to contact the reticle, a second substrate having opposing first and second surfaces. The first surface of the second substrate is coupled to the second surface of the first substrate. A plurality of cooling elements are located between the first surface of the second substrate and the second surface of the first substrate. The cooling elements are configured to cause electrons to travel from the second surface of the first substrate to the first surface of the second substrate. Each cooling element is substantially aligned with a respective burl.

Abstract: A lithographic projection apparatus is disclosed for use with an immersion liquid positioned between the projection system and a substrate, Several methods and mechanism are disclosed to protect components of the projection system, substrate table and a liquid confinement system. These include providing a protective coating on a final element of the projection system as well as providing one or more sacrificial bodies upstream of the components. A two component final optical element of CaF2 is also disclosed.
