  • Patent number: 10262882
    Abstract: A method includes causing a carrier of an overhead hoist transfer system (OHT) to latch onto a top latch of a first semiconductor wafer transportation pod, the first semiconductor wafer transportation pod comprising a top latching mechanism configured to selectively connect to another pod or a carrier mechanism of an overhead hoist transfer (OHT) system, and a bottom latching mechanism configured to selectively connect to another pod. The method further includes rotating the first semiconductor wafer transportation pod such that the top latching mechanism of the first semiconductor wafer transportation pod latches on to a second semiconductor wafer transportation pod.
    Type: Grant

  • Patent number: 8867018
    Abstract: A method for improving alignment in a photolithography machine is provided. The method comprises identifying first empirical alignment data that has been determined from use of a target photomask within at least one non-target tool, and identifying second empirical alignment data that has been determined from use of a non-target photomask within a target tool. The method continues by identifying third empirical alignment data that has been determined from use of a non-target photomask within at least one non-target tool, and calculating from the first, second, and third empirical alignment data a predicted alignment data for the target photomask with the target tool. The method then proceeds by aligning the target photomask within the target tool using the predicted alignment data, exposing a pattern from the target photomask onto the wafer in the target tool, and further processing the exposed wafer.

  • Patent number: 8825191
    Abstract: A method for aligning a photolithographic machine in an automated semiconductor manufacturing system is provided. The method may include identifying a maximum precision degree for a wafer and identifying a maximum overlay correction value. The method may simulate one or more algorithms to determine whether an algorithm aligns a leading lot within alignment specifications. The method may align a photolithography machine using an algorithm selected based on the simulations.
