Title: The Innovations of Guy Parsey

Introduction

Guy Parsey is a notable inventor based in Ann Arbor, MI (US). He has made significant contributions to the field of lithography, particularly in the calibration and control of stochastic defects. With a total of 6 patents to his name, Parsey continues to push the boundaries of technology.

Latest Patents

Among his latest patents is a method to calibrate, predict, and control stochastic defects in EUV lithography. This innovative approach involves receiving an initial probability of occurrence of a stochastic defect over an inspection area of a workpiece. The locations of these defects are sorted by their initial probability, allowing for a cumulative expected defect count to be determined. This count is then normalized to represent a fraction of the total expected defect count. Additionally, another patent focuses on imaging one or more defects within the inspection area using an optical tool or an electron beam tool. This method generates a probability of occurrence for each defect location, which is then grouped into probability bins. The consistency between the initial probability and observed results is assessed, enabling the model to be fine-tuned based on this consistency.
