  • Apparatus and method for fine alignment of a photomask to a semiconductor wafer
    Patent number: 4265542
    Abstract: A method and apparatus are disclosed for fine aligning a photomask to a semiconductor using the interference and diffraction effects produced by coherent light impinging upon or passing through repetitive patterns on a photomask and a semiconductor. A plurality of photodetectors are employed to convert the interference information into phase dependent electrical signals that are used to control conventional X, Y and .theta. workpiece positioning mechanisms.
