Latest Patents
Srinivasan's latest patents include a method for characterizing defects on semiconductor wafers. This method involves detecting and characterizing defects on a test surface by aligning and comparing a three-dimensional image of the test surface with a defect-free reference surface. Intensity differences between corresponding pixels that exceed a predefined threshold are identified as defect pixels. The method also groups pixels of the reference image according to their z values to identify different physical layers, allowing for a more accurate analysis of surface properties.
Another significant patent is a method of establishing thresholds for image comparison. This method optimizes intensity-comparison thresholds used to detect defects by analyzing groups of pixels separately based on their elevation. This approach ensures that different surface layers, which may have varying image properties, are accurately assessed for defect detection.
