SUBSTRATE HOLDER AND METHOD
摘要:
A substrate holder for holding a substrate comprising a frame and a surface clamping device arranged on an underside of the frame configured to electrostatically attract an upper surface of the substrate from above the substrate. The substrate holder can be used to contactlessly hold and deform the substrate and thereby control a shape of the substrate. The substrate holder is suitable for use in a semiconductor processing apparatus and can operate in a vacuum or near-vacuum environment, such as in an EUV lithographic apparatus.
