  • Patent number: 6612797
    Abstract: A SMIF interface is disclosed for buffering one or more cassettes within a minienvironment affixed to a process tool. The interface includes a load port formed of a port door and a port plate circumjacent thereabout, and a minienvironment mounted to port plate. The SMIF interface and/or process tool includes at least one shelf for storing a cassette after the load port separates the cassette from its transport pod. In operation, while a first cassette is located within the process tool, a second pod is seated on the load port, the cassette is separated from the pod and the cassette is stored on a storage shelf. When processing on the first cassette is completed, the second cassette is loaded into the processing tool. The first cassette is returned to the pod and removed from the load port. A cassette from a new pod is then seated on the load port, separated from its pod and stored on the storage shelf. This process continues until processing on each scheduled wafer lot is completed.

  • Patent number: 6364595
    Abstract: A reticle transfer system is disclosed for transferring reticles between a reticle-carrying SMIF container and a process tool. The reticle transfer system according to the present invention includes an arm assembly having a transfer arm and a gripping mechanism affixed to the end of the transfer arm. Once the container carrying the reticle has been opened, the gripping mechanism is rotated and translated to a position adjacent the reticle so that it may access the reticle and transfer it into the minienvironment through an access port in the minienvironment. In order to precisely, easily and repeatedly position the gripping mechanism in the desired location to grip and transfer the reticle, the gripping mechanism includes four downwardly extending posts spaced apart from each other so as to contact an outer rim of the container door as the gripping mechanism is lowered into position to grip and transfer the reticle.

  • Patent number: 6261044
    Abstract: A system is disclosed for retaining a pod door on a port door at a load port, and for removing contaminants, particulates and/or gasses from between the pod and port door surfaces and from within the interior of the pod door. According to a preferred embodiment of the present invention, a vacuum source may be provided within, adjacent to, or remote from a process tool, which vacuum source is connected to a vacuum port in the front surface of a port door. The vacuum is provided to produce a negative pressure between juxtaposed surfaces of the port and pod doors. The negative pressure accomplishes two functions. First, the negative pressure serves to hold the pod door firmly against the port door to prevent vibration, tilting and/or movement of the pod door with respect to the port door while the pod and port doors are stowed within the process tool.

  • Patent number: 6216873
    Abstract: A reticle support mechanism is disclosed in which a reticle may be quickly and easily located and removed, and which is capable of securely supporting a reticle for storage and/or transport. A preferred embodiment of the present invention includes a pair of reticle supports mounted to a door of a container, and a pair of reticle retainers mounted to a shell of the container. When the container shell is coupled with the container door, sections of the reticle support and reticle retainer engage chamfered edges of the reticle and sandwich the reticle in a secure position within the container. As a result of engaging the reticle at its chamfered edges, potentially harmful contact with the upper and lower surfaces and vertical edges of the reticle is avoided.

  • Patent number: 6164664
    Abstract: An interface seal between a gas flow line within a support surface for a pod and a flow valve mounted within the pod. The kinematic coupling between a pod and support surface aligns a pair of inlet and outlet valves on a bottom surface of the pod with a corresponding pair of inlet and outlet holes in the support surface, through which gas may be injected into and removed from the pod, respectively. The interface according to the various embodiments of the invention provides a durable seal substantially preventing leakage between the pod and support surface while at the same time being compatible with kinematic couplings. In embodiments of the invention, the seal is thin and flexible, and expands into engagement with the pod to establish the seal. This type of interface seal will not interfere with the proper seating of the pod on the kinematic pins.

  • Patent number: 6056026
    Abstract: A valve seated within a SMIF pod support platform is disclosed for activating and deactivating the flow of gas to a pod on the platform. In preferred embodiments, the valve includes a central poppet capable of moving between a first, closed position where the poppet blocks the flow of gas through the valve, and a second, open position where the poppet allows gas flow through the valve. In the absence of a pod on the support platform, pressurized gas from the gas source downstream of the valve biases the poppet into the first position to thereby block gas flow. In this first position, a top portion of the poppet extends slightly above the upper surface of the pod support platform. When a pod is seated on the support platform, the weight of the pod moves the poppet from its first position to its second position where gas is allowed to flow through the valve and into the pod to allow purging of the pod.
