Latest Patents
One of his latest patents is titled "Method for auto-learning tool matching." This invention focuses on a method of tool matching that utilizes an auto-learning feedback loop to update a library of key parameters. The process involves performing measurements on a control wafer to collect parameters associated with the process or analysis tool being matched. When deviations in parameters correlate with a correctable tool condition, these parameters are added to the library. This methodology allows for more frequent tool matching by monitoring an automatically updated list of key parameters, rather than reviewing the entire set of parameters each time.
Another significant patent is "Modeling and cross correlation of design predicted criticalities for optimization of semiconductor manufacturing." This invention includes a feedback loop where information from the manufacturing process is provided to a cross-correlation engine for optimization. The information encompasses parametric data, functional details, and hot spot determinations. By sharing this information, the design intent can be reflected in the manufacturing metrology space, leading to more intelligent metrology and reduced cycle times.
