  • Publication number: 20020094257
    Abstract: A reticle management system is disclosed including a sorter coupled to one or more stockers that allow a customized configuration of the overall reticle management system. The stockers may be bare reticle stockers, closed container reticle stockers, or both. In embodiments of the present invention, the reticle management system includes between one and six individual bare reticle stockers and/or closed container stockers for storing reticles affixed to a reticle sorter. The sorter includes a reticle inspection station for inspecting the reticles, a plurality of input/output (I/O) load ports and a reticle handling robot for transferring the reticles between the stockers, the inspection station and the I/O load ports. The management system further includes a control unit for housing control electronics for the system.

  • Publication number: 20020048506
    Abstract: The present invention is an edge grip aligner with buffering capabilities and a method for increasing the throughput of wafers through the device. According to one embodiment, the present invention has first and second buffer arms, and a chuck arm. A workpiece can be aligned while supported on the chuck arm. Once the workpiece is aligned, the chuck arm transfers the workpiece to the buffer arms so that a second workpiece can be aligned on the chuck arm. While the second workpiece is being aligned, an end effector can transfer the first workpiece away from the buffer arms and retrieve another workpiece to place upon the chuck arm.

  • Patent number: 6326755
    Abstract: A dual paddle end effector robot is disclosed which is capable of parallel processing of workpieces. The end effector includes a lower paddle rotatably coupled to an end of the distal link, and an upper paddle rotatably coupled to the lower paddle. The lower paddle supports a drive assembly capable of rotating the upper paddle with respect to the lower paddle. In one embodiment of the present invention, the dual paddle end effector robot may be used within a wafer sorter to perform parallel processing of workpieces on a pair of aligners within the sorter. In such an embodiment, the robot may first acquire a pair of workpieces from adjacent shelves within the workpiece cassette. After withdrawing from the cassette, the respective paddles on the end effector may fan out and transfer the wafers to the chucks of the respective aligners.

  • Patent number: 5984116
    Abstract: A substrate support apparatus for supporting one or more substrates in a substrate carrier for achieving a minimum amount of sagging of the substrates. A first support rod is positioned to support one side of each substrate along a first support contact line and a second support rod is positioned to support the other side of the substrate along a second support contact line. The first and second support contact lines are referenced to a centerline of the substrate. In particular, both contact lines are offset by a certain distance on either side of the centerline, where the particular offset of the support lines is determined by finite element analysis of the substrate to achieve as little sag as possible. The rod support member preferably includes two cantilevered beams mounted on either side of each of the support rods. Also, a plurality of support rods and corresponding rod support members are provided for supporting as many substrates as necessary in the carrier.

  • Patent number: 5853214
    Abstract: A substrate aligner for a substrate carrier or cassette including an engagement assembly for moving and maintaining one or more substrates into an aligned position when closed, and an actuator assembly for opening and closing the engagement assembly. In one embodiment, the engagement assembly includes front and back engagement assemblies for mounting at opposite corners of the housing to thereby interface opposite comers of the substrates. Each engagement assembly preferably includes a roller for interfacing a corresponding edge of each the substrates, where the front assembly includes two rollers for interfacing front edges and adjacent side edges, and the back engagement assembly includes two rollers for interfacing the back edges and the opposite side edges of the substrates. In this manner, the engagement assembly interfaces all four edges of each substrate to thereby manipulate and maintain the substrates into a substantially aligned position when closed.

  • Patent number: 5834915
    Abstract: A modular, transportable housing for storing substrates, such as semi-conductor wafers and masks, and for maintaining such substrates in a substantially clean environment. Substrates are supported within the housing by a plurality of combs which maintain the substrates in spaced relationship relative to each other. Access to the interior of the housing is permitted by a pivotal door assembly. A docking unit permits interface of the housing with a clean environment. Control circuitry provided in the docking unit detects the presence of a housing and loads/unloads the housing as directed by a host computer through a communication link. A memory device is preferably mounted to the housing for storing history and other information about the substrates within the housing. The host computer directs the control circuitry to retrieve the substrate information from the memory and relay the information to the host computer. During or after processing of the substrates, the host computer updates the memory as desired.

  • Patent number: 5664926
    Abstract: A stage assembly for a substrate processing system including a cassette support assembly for receiving and supporting a cassette and an actuation and support assembly for supporting and moving the cassette and cassette support assembly between a loading position and a processing position. The processing position provides convenient and efficient access by a central processing system, and the loading position preferably places each cassette closer to, and aligned with, a front panel of the processing system for convenient access by an operator. The actuator and support assembly preferably includes a frame assembly and a rotating plate pivotally mounted to the frame assembly, where the cassette support assembly is mounted to the rotating plate for pivoting relative to the frame assembly. An actuator assembly mounted to the frame assembly flits the cassette support assembly between the loading and processing positions. A shaft assembly pivotally mounts the cassette support assembly to the rotating plate.
