Abstract
A rectangular substrate bed has on its top surface a row of disk-shaped holding members on which disk-shaped substrates are laterally positioned by a frame member having circular openings which expose the substrates. Seals are provided on each holding member so that substrates can be held in place by vacuum. The frame member is fixed to the substrate bed by clamps having pins which are received in bores at opposite ends of the substrate bed and the frame member.
