ABSTRACT:
A semiconductor processing system for wafers or other semiconductor articles. The system uses an interface section at an end of the machine accessible from the clean room. A plurality of processing stations are arranged away from the clean room interface. A transfer subsystem removes wafers from supporting carriers, and positions both the wafers and carriers onto a carrousel which is used as an inventory storage. Wafers are shuttled between the inventory and processing stations by a robotic conveyor which is oriented to move toward and away from the interface end. The system processes the wafers without wafer carriers.
