摘要 |
An apparatus and a method to hold a patterning device configured to impart a beam of radiation with a pattern in its cross-section. The apparatus includes a base configured to support the patterning device and an inner cover couplable to the base. The inner cover includes a restraining mechanism that, upon an application of a force external to the inner cover, is configured to provide an in-plane force to the patterning device to restrain movement of the patterning device, the in-plane force being substantially parallel to a patterning surface of the patterning device. |

1. An apparatus, comprising:
a base configured to support a patterning device, the patterning device configured to impart a beam of radiation with a pattern in its cross-section; and a cover couplable to the base, the cover comprising a restraining mechanism that, upon an application of a force external to the cover, is configured to provide an in-plane force to the patterning device to restrain movement of the patterning device, the in-plane force being substantially parallel to a patterning surface of the patterning device and applied via a structure of the restraining mechanism arranged to only contact a side of the patterning device transverse to the patterning surface, the side having an edge, and arranged to apply the in-plane force without substantial sliding contact between the structure and the side and edge of the patterning device. |
