Single workpiece processing chamber with tilting load/unload upper rim

A process chamber for processing semi-conductor wafers. The chamber includes at least one rotor within the process chamber. The rotor is adapted to receive and/or process semi-conductor wafers. The top of the process chamber also includes a tiltable rim. This rim tilts from a non-inclined position to an inclined position. The wafers may be loaded into and unloaded from the process chamber when the rim is in its inclined position.
