  • Patent number: 7819079
    Abstract: The present invention generally provides an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool) that is easily configurable, has an increased system throughput, increased system reliability, improved device yield performance, a more repeatable wafer processing history (or wafer history), and a reduced footprint. In one embodiment, the cluster tool is adapted to perform a track lithography process in which a substrate is coated with a photosensitive material, is then transferred to a stepper/scanner, which exposes the photosensitive material to some form of radiation to form a pattern in the photosensitive material, and then certain portions of the photosensitive material are removed in a developing process completed in the cluster tool.

  • Publication number: 20100178146
    Abstract: A substrate transporting robot apparatus is disclosed which is adapted to transport a substrate to and from a chamber of an electronic device processing system. The apparatus may include an upper arm rotatable in an X-Y plane, a forearm rotatable relative to the upper arm in the X-Y plane, and a wrist member rotatable relative to the forearm in the X-Y plane, the wrist member including an end effector adapted to carry a substrate. The wrist member may be subjected to independent rotation such that various degrees of yaw may be imparted to the wrist member. In some aspects, the independent rotation is provided without a motive power device (e.g., motor) being provided on the arms or wrist member, i.e., the wrist member may be remotely driven. Systems and methods using the robot apparatus are also provided as are numerous other aspects.

  • Patent number: 7673735
    Abstract: In a semiconductor fabrication facility, a conveyor transports substrate carriers. The substrate carriers are unloaded from the conveyor and loaded onto the conveyor without stopping the conveyor. A load and/or unload mechanism lifts the substrate carriers from the conveyor during unloading operations, while matching the horizontal speed of the conveyor. Similarly, during loading operations, the load/unload mechanism lowers a substrate carrier into engagement with the conveyor while matching the horizontal speed of the conveyor. Individual substrates, without carriers, may be similarly loaded and/or unloaded from a conveyor.
