    Abstract: An arrangement for supporting a mask 10 comprises a pair of members 14. The mask 10 is held against each member 14 by a vacuum arrangement which prevents relative motion between the mask and members. The members 14 are compliant such that they accommodate flatness variations in the mask 10 but without deforming the mask 10.
