Abstract:
1. A substrate support configured to support a substrate within a lithography system, the substrate support comprising: a support surface configured to support a bottom face of the substrate such that the bottom face lies in a plane substantially parallel to the support surface; a lifting structure comprising a lifting face and a lifting base and configured to move the lifting face and the lifting base between a first position, in which the lifting face supports the bottom face of the substrate at a position set apart from the support surface, and a second position, in which the lifting structure is arranged such that the lifting structure does not prevent the substrate from being supported by the support surface, the lifting structure being configured such that, in moving between the first and second positions, the lifting structure moves the substrate in a combination of movement substantially perpendicular to a plane parallel to the support surface and movement substantially parallel to the support surface; and an actuator configured to control the movement of the lifting structure between the first and second positions, the actuator comprising rigid link mounted to the lifting base, such that the rigid link rotates relative to the lifting base about an axis substantially parallel to a plane of the support surface, wherein the actuator is configured such that, in moving the lifting face between the first and second positions, the lifting face does not rotate about the axis substantially-parallel to the plane of the support surface.
