SINGLE WAFER PROCESSOR APPARATUS |
摘要 |
A single wafer processing apparatus includes a portable processing head that can be a portable module or a movable unit mounted to a supporting machine frame. The processing head has movable fingers adapted to grip a wafer. The fingers protrude from a protective wafer plate. Indexing and rotation monitoring assemblies are provided for automation of the wafer processing steps. A complementary processing base includes an upwardly-open bowl that receives a wafer held by the portable processing head. It has a full-diameter movable bottom wall for rapid draining purposes. Liquid and/or gas jets and nozzles supply fluids required within the bowl for processing of wafers.
