Abstract

A semiconductor wafer processing tool has a support structure for a coarse motion positioning system. A measurement head having a rigid super structure is supported from the support structure by vibration isolators and a top plate is mounted to the super structure. A vacuum transfer chuck is releasably carried by the coarse motion positioning system and releasably adherable to the top plate by application of vacuum. The vacuum transfer chuck supports a semiconductor wafer.
