  • Publication number: 20080199282
    Abstract: Embodiments generally provide an apparatus and method for processing substrates using a multi-chamber processing system (e.g., a cluster tool). In one embodiment, the cluster tool is adapted to perform a track lithography process in which a photosensitive material is applied to a substrate, patterned in a stepper/scanner, and then removed in a developing process completed in the cluster tool. In one embodiment of the cluster tool, substrates are grouped together in groups of two or more for transfer or processing to improve system throughput, reduce the number of moves a robot has to make to transfer a batch of substrates between the processing chambers, and thus increase system reliability. Embodiments also provide for a method and apparatus that are used to increase the reliability of the substrate transfer process to reduce system down time.

  • Publication number: 20030237013
    Abstract: The present invention relates to a method and apparatus for providing clocks for network equipment. According to the method, clock input signals are first received from a primary and a redundant system; the clock input signal is then selected from the primary system; the selected clock input signal from the primary system is distributed to the interfaces needing a clock signal in the network equipment, respectively. The apparatus comprises a clock input selection module and a clock input distributing module. The clock input selection module selects the clock input signal received from the primary system, and the clock input signal from the primary system is then sent to the clock input distributing module. The clock input distributing module distributes the received clock input signal and outputs the distributed signal.

  • Patent number: 6580955
    Abstract: An apparatus, method and medium is provided for increasing the efficiency with which wafers are transferred among different processing chambers in a wafer processing facility. A multi-slot cooling chamber allows multiple wafers to be cooled while other wafers are subjected to processing steps in other chambers. Each wafer in the processing sequence is assigned a priority level depending on its processing stage, and this priority level is used to sequence the movement of wafers between chambers. A look-ahead feature prevents low-priority wafer transfers from occurring if such transfers would occur just prior to the scheduling of a high-priority wafer transfer.
