  • Patent number: 10086511
    Abstract: Linear semiconductor handling systems provide more balanced processing capacity using various techniques to provide increased processing capacity to relatively slow processes. This may include use of hexagonal vacuum chambers to provide additional facets for slow process modules, use of circulating process modules to provide more processing capacity at a single facet of a vacuum chamber, or the use of wide process modules having multiple processing sites. This approach may be used, for example, to balance processing capacity in a typical process that includes plasma enhanced chemical vapor deposition steps and bevel etch steps.

  • Patent number: 9914626
    Abstract: The present invention relates to an order picker with a wiring mechanism, belonging to the technical field of manned elevation equipment. The order picker with a wiring mechanism comprises a stationary part, an elevation mechanism and an elevation part, wherein the wire suitable for transmitting signals is connected between the stationary part and the elevation part. It also comprises a wire accumulator which acts on the wire in such a way that the wire is always tensioned between the stationary part and the elevation part; when the elevation part is raised, the wire accumulator starts to pay out the wire, and when the elevation part is lowered, the wire accumulator starts to stow the wire. The present invention adopts a wire accumulator structure which can avoid the wires which come from the chassis being nipped during elevation of the elevation structure.

  • Patent number: 7204669
    Abstract: A method and apparatus for preventing substrate damage in a factory interface. In one embodiment, a method for preventing substrate damage in a factory interface includes the steps of receiving an indicia of potential substrate damage, and automatically preventing substrates from moving out of a substrate storage cassette in response to the received indicia. The indicia may be a seismic warning signal, among others. In another embodiment, a method for preventing substrate damage in a factory interface includes the steps of moving a pod door in a first direction to a position spaced-apart and adjacent a pod, and moving the pod door laterally in a second direction to close the pod. The lateral closing motion of the pod door urges substrates, which may be misaligned in the pod, into a predefined position within the pod.

  • Patent number: 7112028
    Abstract: A lift dolly is provided for lifting and transporting stand-mounted power tools and the like, with little effort. The dolly includes a pair of platforms and a wheel system having at least three castors extending downwardly from the platforms. The dolly is designed such that one step onto a latching or locking mechanism by the operator causes the wheel system to be forced downward relative to the stand thereby slightly lifting the power tool and stand off of the ground and enabling transport of same via the castors. Another step on the locking or latching mechanism disengages the wheel system and permits gravity to return the stand and tool firmly to the ground for use.
