  • Wafer carrier mapping sensor assembly
    Patent number: 6897463
    Abstract: A wafer mapping sensor assembly includes a housing, and an imaging array positioned therein. Imaging optics are positioned relative to the array to focus an image upon the array. An illumination source is configured to direct illumination toward the wafer, where such illumination is reflected by the wafer. An optical element is interposed between the source and the wafer. The optical element directs the illumination to reduce the effects of undesirable illumination.

  • System for mapping wafers using predictive dynamic lighting
    Patent number: 6825486
    Abstract: A wafer mapping system includes an imaging array, at least one lighting module and a controller coupled to the imaging array and the lighting module. The controller is adapted to receive information relative to an initial acquired wafer image and adjust illumination from the lighting module based upon the initial acquired wafer image, and acquire a subsequent wafer image using the adjusted illumination.
