Abstract

A wafer processing system for spin processing photoresist liquid on a silicon wafer and automatically sequencing them through the processor includes a shuttle having upper and lower air bearing slides. The upper slide receives the wafer from a supply magazine and centers it on a rotating chuck and the lower slide of the shuttle receives the wafer from the chuck and allows it to be transferred to a receive track.
