Patent ID: 7080652

Claim:
A system for processing wafers comprising: an interface section having a plurality of positions for holding wafer carriers, with each wafer carrier having a plurality of grooves for holding an array of wafers, at the edges of the wafers; a process section including at least one process chamber; a plurality of liquid spray nozzles in the process chamber; a rotor rotatable within the process chamber; one or more combs in the rotor for holding the array of wafers within the rotor; a pair of retainer assemblies on the rotor, with each retainer assembly pivotably attached to the rotor for retaining the wafers in place in the rotor with each retainer assembly moveable along a predetermined path of travel between an open position and a closed position and with the retainer assemblies robotically actuated to move between the open and closed positions; and a robot movable between the interface section to the process section, with the robot having an arm and a wafer transfer implement at an end of the arm for picking up an array of wafers.
