摘要:
The present invention generally comprises an apparatus for transporting containers between a first transport system and a second transport system. In one embodiment, the first transport system comprises a ceiling-based conveyor and the second transport system comprises a floor-based conveyor. The present invention may further include storage shelves, preferably substantially horizontally aligned about a common vertical plane with a section of one of the transport systems. The transport system may be located either directly above the uppermost storage shelf or beneath the lowermost storage shelf in order to add storage capacity within the fab. A vertical module transports containers between the transport systems and the at least one storage shelf.

An exemplary embodiment a substrate transport system is provided. The system has a guideway and at least one transport vehicle. The transport vehicle is adapted for holding at least one substrate and capable of being supported from and moving along the guideway. The guideway comprises at least one travel lane for the vehicle and at least one access lane offset from the travel lane allowing the vehicle selectable access on and off the travel lane.

A positioning device to position one or more plates of electronic circuits with respect to an operating unit. The device comprises a rotary member which rotates selectively between a first operating position and a second operating position, and a positioning member mounted on the rotary member. The positioning member comprises a frame, which is mounted removably on the rotary member, and a strip of transpirant material on which each plate is rested. The strip is wound between a pair of winding/unwinding rollers, pivoted on the frame. The positioning member also comprises heating means able to heat the wafer to take it to a determinate operating temperature.

A direction change device includes first and second transport passage 3, 4, in which one of the transport passages is disposed at the same vertical position as that of the first transport rail 16, the other is disposed below the one, a rotating unit 22 rotating the transport passages 3, 4 about their central points, a lift unit 23 lifting the transport passages 3, 4 in a vertical direction and a control unit 21. The control unit 21 controls such that when the FOUP 5 is carried out from the transport rail 16 to the transport passage disposed at the same vertical position as that of the transport rail 16, rotating the transport passages 3, 4 by about 90°, carrying out the FOUP 5 from one of the transport passages, and exchanging the respective vertical positions of the first and second transport passages 3, 4.

Substrate processing apparatus having a transport chamber, a linear array of substrate holding modules alongside the transport chamber, and a substrate transport located in the chamber. The chamber can hold an isolated atmosphere, and defines more than one substantially linear transport paths extending longitudinally along the transport chamber. The transport in the chamber is capable of transporting the substrate along the linear transport paths. The transport has a transporter capable of holding and moving the substrate. The transporter interfaces a wall of the transport chamber for moving along at least one of linear paths. The transport chamber has interfaces for mating with other substrate holding modules at opposite ends of the transport chamber. Each interface has an opening through which at least one of the more than one linear transport paths extends, and the transport chamber has a selectably variable longitudinal length between the interfaces.

A conveyor system for conveying a relatively fragile work piece, such as a silicon wafer, to and from a work station where one or more processing operations are performed on the work piece comprises two parallel conveyor belts. Each conveyor belt is mounted on a separate carriage, and the carriages are moveable laterally toward and away from each other during different periods of operation of the conveyor system and also to enable different size work pieces to be carried by the conveyor belts. The conveyor belts are driven by a drive belt system which comprises a fixed length, closed loop drive belt and a pulley arrangement operatively associated with the drive belt for accommodating lateral motion of the carriages while permitting drive of the conveyor belts at all lateral positions of the carriages and without any change in the length of the drive belt. The conveyor system also provides positive handling of the work piece during all conveying and processing operations to minimize breakage of the work piece. The conveyor system incorporates a vertically moveable spindle and chuck at the work station for lowering the work piece to a processing position below the conveyor belt. Centering and sensing apparatus are located at the work station to center the work piece above the chuck and to coordinate the vertical movement of the chuck with the lateral movement of the carriages and to provide the positive handling of the work piece at each stage of transport and processing of the work piece.

In an electronic component manufacturing system, slices are transported in serial fashion between a plurality of work stations. As the slices move through the system, each work station performs a separate manufacturing operation on each slice. The manufacturing operations are performed in immediate succession and within the same time interval so that the slices are processed rapidly and so that slices do not accumulate between the work stations. The slices are maintained in sequence throughout the system so that the operation of the system is more easily controlled.

A magnetic transfer apparatus includes: a magnetomotive force source providing magnetic flux, a first magnetic flux distribution circuit connected to one end of the magnetomotive force source, having a single input terminal and a plurality of output terminals, and distributing the magnetic flux, and a second magnetic flux distribution circuit connected to the other end of the magnetomotive force source, having a single output terminal and a plurality of input terminals, and collecting the distributed magnetic flux. The output terminals of the first magnetic flux distribution circuit are disposed to be adjacent to each other to form a pair with the input terminals of the second magnetic flux distribution circuit.
