Latest Patents
Burov's latest patents focus on a method to calibrate, predict, and control stochastic defects in EUV lithography. The first patent describes a process where an initial probability of occurrence of a stochastic defect over an inspection area of a workpiece is received. All locations of the stochastic defects are sorted by the initial probability of occurrence. A cumulative expected defect count is determined, and this count is normalized to be a fraction of the total expected defect count. Additionally, a number of defect locations is determined to capture potential stochastic defects above a threshold of total stochastic defects. The second patent elaborates on imaging one or more defects within the inspection area using an optical tool or an electron beam tool. A probability of occurrence of a stochastic defect at each of the defect locations is generated using a model. The defect locations are then grouped into probability bins, allowing for a consistency check between the initial probability and observed results, enabling model tuning based on this consistency.
