Abstract
In a method for rinsing and drying a semiconductor workpiece in a micro-environment, the workpiece is placed into a rinser/dryer housing. The rinser/dryer housing is rotated by a rotor motor. The rinser/dryer housing defines a substantially closed rinser/dryer chamber. Rinsing and drying fluids are distributed across at least one face of the semiconductor workpiece by the action of centrifugal force generated during rotation of the housing. A fluid supply system is connected to sequentially supply a rinsing fluid followed by a drying fluid to the chamber as the housing is rotated.
