Abstract:
A transport module for transferring a semiconductor wafer to a vacuum transport system, the vacuum transport system having a central system axis; the module and the system having a footprint defining the area occupied by the module and the system, the transport module comprising:a wafer supply for holding a wafer to be transferred to the vacuum transport system, the wafer supply having a central supply axis;the footprint being proportional to a distance between the central system axis and the central supply axis, the distance being measured along a footprint dimension line extending from the central system axis to the supply axis; anda wafer transfer enclosure having a wafer receiving face provided with a port for receiving the wafer from the wafer supply; the wafer receiving face being spaced from the central supply axis by a wafer feed distance measured perpendicularly with respect to the wafer receiving face; the wafer receiving face being oriented at an acute angle relative to the footprint dimension line so that when the wafer feed distance is projected onto the footprint dimension line the value of the projected wafer feed distance is less than the value of the entire wafer feed distance such that the value of the footprint dimension line is minimized.
