| Zusammenfassung: | An electrostatic chuck for retaining a substrate. The chuck has a clamping surface for receiving the substrate, where the clamping surface is formed of a hard polymeric material filled with carbon nanotubes. Electrodes are disposed beneath the clamping surface, for inducing localized electrostatic charges in the substrate and thereby retaining the substrate against the clamping surface. A base supports the clamping surface and the electrodes. |
