Abstract: A bridging chamber is constructed between adjacent substrate processing workstation systems and connected by ports constructed in the adjacent substrate processing workstation systems. Transport mechanisms are used to move the substrates into and out of the bridging chamber to bypass primary transport systems.

Abstract: A sorter for handling and sorting semiconductor wafers is provided. The sorter has a housing, a handling and transport device and at least one nonproduction wafer buffer module. The housing has at least one holding area for interfacing one or more semiconductor wafer carriers to the housing. The housing defines an access path along which semiconductor wafers are transported between the housing and the one or more semiconductor wafer carriers. The handling and transport device is connected to the housing for transporting semiconductor wafers along the access path. The at least one nonproduction wafer buffer module is connected to the housing. The at least one nonproduction wafer buffer module buffers nonproduction wafers sorted by the sorter to one or more semiconductor wafer carriers.

Abstract: The present invention relates to a method and a system for operating a semiconductor factory. The factory comprises equipment (8) for processing semiconductor wafers, and an automated material handling system (12). The invention comprises clamping a wafer carrier (16) while a wafer is processed by a particular tool (10), continuing clamping the wafer carrier (16) after processing, and unclamping the wafer carrier (16) when the automated material handling system (12) is ready for removing the wafer carrier (16) from the tool (10).

Abstract: A conveyor element (10) for conveying wafer receptacles between a conveyor (12) and a loading station (11) of a manufacturing system in the semiconductor industry has a lifting mechanism (13) to move the wafer receptacle from a first position of the conveyor (12) or the loading station (11) into a second position of the conveyor (12) or of the loading station (11) substantially in a vertical direction. Rollers (14) are provided to move the wafer receptacle from the second position of the conveyor (12) along a substantially horizontal direction to the second position of the loading station (11) or from the second position of the loading station (11) to the second position of the conveyor (12).

Abstract: A processing tool bay within a semiconductor fabrication site, including a plurality of semiconductor processing tools for processing wafers being arranged in two opposite rows. An intrabay transport system for transporting wafer carriers around the process tool bay at least in a vertical plane in front of one of said two rows of semiconductor process tools comprises at least one vehicle for receiving and delivering a wafer carrier to and from any one semiconductor process tool of said plurality of semiconductor process tools, and a vehicle guiding mechanism. The vehicle comprises a circular compartment structure including a plurality of compartments for buffering said wafer carrier between receiving it at a first location and delivering it at a second location. Each compartment is arranged for accommodating one wafer carrier. The compartment structure is rotatable around a symmetry axis of itself for an alignment.

Abstract: A vehicle (10) for transporting a container (12) and for loading and unloading a load port (14) is disclosed. The vehicle (10) comprises a frame (16), a container holder (26) mounted to the frame (16), and front wheels (18) and rear wheels (20) mounted to the frame (16). The front wheels (18) are movable with respect to the rear wheels (20), so that the critical footprint of the vehicle is reduced during loading and unloading. The vehicle is particularly useful in personal guided systems and methods for loading and unloading wafer containers.

Abstract: An apparatus related to a lot signalling device used to find misplaced lots. A remote control signalling device comprises a receiver section (5) for receiving an RF-command including a unique address of at least one of said plurality of remote control signalling devices (3) from a central control unit (1), an address memory (6) for storing the address of said remote control signalling device, an output section (7) for signalling an alarm upon receiving the RF-command, if said address included in the RF-command matches the stored address in said address memory (6). A method for processing items at different process stages comprises the steps of: transmitting RF-commands including a unique address of at least one of said plurality of remote control signalling devices by a central control unit (1), signalling an alarm by said remote control signalling device (3) upon reception of an RF-command from said central control unit (1).

Abstract: In a transportation system (100, 200) for wafers, a wafer container (100) has kinematic coupling grooves, and a support surface (200) has kinematic coupling pins. Grooves and pins are at least partially electrically conductive to allow monitoring the correct position of the container by measuring electrical resistance, as well as to allow signal exchange to and from the container (100). The kinematic coupling pins have first and second surface areas that are electrically isolated.
