A board game including a game board device with a game board surface with a game board pattern. A transparent shield component is configured to cover the game board surface where a frame segment is disposed around a proximate edge of the game board surface and form a section of space between the game board surface and the transparent shield for containing at least one or more magnetic game piece implements. A stylus implement is configured to be operable for generally moving the at least one or more game piece implements from one position to another across the game board surface by magnetically attaching at least one game implement to the stylus implement and sliding the stylus implement across the transparent shield component.

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.

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 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.

A device for carrying shuffleboard pucks and similar disc-shaped objects comprising a fixed strip member and a laterally movable strip member held in a common plane by a supporting frame to define a support surface. A plurality of lugs are disposed on both strip members to retain shuffleboard pucks on the aforesaid surface of the carrying device in a planar configuration upon the laterally movable strip member being drawn toward and held in close proximity to the fixed strip member.

A port door providing an interface into a processing tool is provided. The port door includes first and second arms pivotably mounted on a top edge of the port door. The first and second arms are configured to extend from a plane of the port door towards a carrier containing substrates for the processing tool. The first arm has an emitter transmitting a beam that is split into a plurality of sub-beams within the first arm. The second arm has a plurality of sensors receiving corresponding sub-beams, wherein one of sub-beams provides information as to a position of an end effector relative to a gap between the substrates in the carrier.
