Abstract:
1. A method for processing semiconductor wafers comprising: providing a plurality of robotic handling facilities serially joined to each other to form a substantially linear transport chamber through which wafers can be transferred from each robotic handling facility, the substantially linear transport chamber being sealed to hold a controlled atmosphere and configured so that the transfer of wafers is effected via handoff of a wafer between neighboring robotic handling facilities, wherein at least a portion of the plurality of robotic handling facilities include an interior accessible through a plurality of entrances, each of the plurality of robotic handling facilities including at least one scara arm having three arm links serially coupled to one another, the three arm links being rotatable about a shoulder at a proximate end and having a substrate holder rotatably coupled at a distal end of the three arm links; and providing a multi-entry process module coupled to at least one of the plurality of robotic facilities, where each entry of the multi-entry process module is accessed by at least one of the at least one scara arm.
