摘要： An adaptor plate for allowing 200 mm SMIF pods carrying one or more semiconductor wafers to be used on an access port of a wafer processing station configured to accept a 300 mm SMIF pod. The adaptor plate has a substantially circular outer circumference conforming substantially in size and shape to the outer circumference of a conventional 300 mm SMIF pod, and a central opening conforming substantially in size and shape to a conventional rectangular 200 mm SMIF pod. The one or more semiconductor wafers are supported on pod door of the pod, and the semiconductor wafers and pod door are lowered through the central opening in the adaptor plate into the wafer processing station. With the adaptor plate supported on the access port, and a cover of the 200 mm SMIF pod supported around the central opening, the access port is entirely covered and entry of contaminants into the processing station through the access port is prevented.

摘要： A SMIF pod capable of supporting a cassette at points in the pod located directly over or near a kinematic coupling between the pod and a surface on which the pod is supported. Even if the pod shell warps or otherwise deforms, the three points of contact between the pod and the support surface at the kinematic couplings will always remain at a fixed, controllable and repeatable position. The present invention makes use of this fact by supporting the cassette at or near the three kinematic coupling points. Moreover, the support structure is not affixed to the top or sides of the pod shell. Thus, the position of the cassette, and wafers supported therein, will similarly remain at a fixed, controllable and repeatable position, substantially unaffected by any pod shell deformation which may occur.

摘要： A storage, delivery and retrieval system having a rear wall to which is affixed a plurality of shelves capable of supporting one or more wafer-carrying pods. The structure further includes a pair of vertical rails lying in a plane spaced from and substantially parallel to the shelf-supporting wall. The horizontal rail extends between and is translationally mounted to the vertical rails, which horizontal rail supports a gripper capable of movement along the horizontal rail. The movement of the horizontal rail along the vertical rails, and the movement of the gripper along the horizontal rail, allows the gripper to be positioned at any location within an X-Z plane including the storage shelves. The system includes a two-dimensional transport system. That is, all transport of the pods by the system occurs without the pods ever leaving the X-Z plane of the shelves. This feature contributes to the overall small footprint of the system. Additionally, the gripper moves around in the same plane as the pods, and the rails have a small profile and operate directly adjacent the storage shelves. These features further contribute to the storage, delivery and retrieval system according to the present invention.

摘要： A system for providing uniform, controlled and efficient purge gas flow rates and gas flow patterns for removing contaminants and/or particulates from wafers within a pod. The purge system includes seals at the interfaces between the gas inlet and removal lines to substantially prevent leakage at the interfaces. The system may establish seals at the inlet and outlet without having to use conventional fluid flow pins extending above the support surface. The negative pressure applied at the outlet controls the flow rate through the pod, and the rate at which gas leaves the pod will limit the rate at which gas may enter the pod. In a preferred embodiment, the inlet flow is approximately equal to the outlet flow. With substantially equal inlet and outlet pressures, the purging gas flows through the upper and lower portions of the pod in a substantially uniform flow pattern so that contaminants and particulates are removed evenly from wafers throughout the pod. As an alternative to the normal purge and/or trickle modes of operation, the system may remove a volume of gas from a pod and replace it with a new volume of gas by operating the low pressure source with the high pressure source turned off. Further still, the flow lines may include flow rate control systems that provide purging flow for a predetermined time interval, and thereafter provide a trickle flow as long as the pod is seated on the support surface.
摘要翻译： 一种用于提供均匀，受控和有效的吹扫气体流速和气流模式的系统，用于从荚内的晶片中去除污染物和/或颗粒物。 吹扫系统包括在气体入口和排出管线之间的界面处的密封，以基本上防止在界面处的泄漏。 该系统可以在入口和出口处建立密封件，而不必使用在支撑表面上方延伸的常规流体流动销。 在出口处施加的负压控制通过荚的流速，并且气体离开荚的速率将限制气体可以进入荚的速率。 在优选实施例中，入口流大致等于出口流。 具有基本上相等的入口和出口压力，净化气体以大致均匀的流动方式流过容器的上部和下部，使得污染物和微粒从整个容器中的晶片均匀地除去。 作为正常吹扫和/或滴流操作模式的替代方案，系统可以从容器中去除一定体积的气体，并通过在高压源关闭的情况下操作低压源来替换新的体积的气体。 此外，流动管线可以包括流量控制系统，其提供预定时间间隔的清洗流量，并且此后提供涓流流动，只要荚座位于支撑表面上即可。

摘要： A rotating and translating support assembly for receiving a front-opening pod according to applicable SEMI standards, and thereafter rotating the pod to a desired orientation. In this way, a number of pods may be received at interface ports of a minienvironment, and each of the pods and ports may be angled toward and aligned with a single, 2-arm pick and place robot. In a preferred embodiment of the present invention, the rotating and translating support assembly comprises a plate rotationally and translationally mounted on a shelf extending from the minienvironment adjacent to a front-opening interface port. In one embodiment, the support plate may be mounted on a shaft attached to a rotating assembly, such as for example a worm and drive gear. The rotating assembly may in turn be mounted on a translating assembly, such as for example a carriage riding on a lead screw. The rotating and translating assemblies may be controlled by a host computer, so as to rotate and translate a pod received on the support plate, to align the pod with an interface port which may be provided at an angle with respect to the front of the minienvironment.

摘要： 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. By providing a buffer of cassettes within the minienvironment of the SMIF interface, the processing tool is no longer dependent on timely delivery of pods to the interface to ensure that the process tool does not sit idle.

摘要： 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. Once the four posts are seated in contact with the outer rim of the container door, the gripping mechanism is fixed in the proper position so that a pair of grippers within the gripping mechanism may rotate inward and grip the reticle. The posts also allow proper positioning of the gripping mechanism with respect to the container door and support platform within the minienvironment when returning the reticle to the container door or depositing the reticle on the minienvironment support platform.

摘要： A wafer mapping system is disclosed mounted to the port door of a process tool. As the port door is lowered away from the access port of the process tool in order to allow wafer transfer through the port, the wafer mapping system according to the present invention detects the presence and position of the various wafers in the pod shell, which information may then be stored in memory for later use. As such, wafer mapping according to this system occurs without additional processing steps or time. The port door is lowered by a servo drive which allows the precise position of the port door to be identified at any given time. As such, the position of a wafer within the pod shell may be precisely identified by the wafer mapping system mounted on the port door as the door is lowered.
