Latest Patents
One of his latest patents is titled "Defect filtering optical verification process." This invention involves an apparatus and method for optical lithography verification, which includes filtering a lithography simulation of proposed sub-lightwave pattern formations. This process occurs during at least one design phase or manufacturing phase of an article of manufacture that has sub-lightwave structures. The invention aims to detect design phase or manufacturing phase defects in response to the filtering of the lithography simulation.
Another significant patent is the "Method of verifying photomask data based on models of etch and lithography processes." This patent describes a process where a photomask dataset corresponding to a target pattern is verified by simulating a resist pattern that will be formed in a resist layer through a lithography process. It also involves simulating an etched pattern that will be created in a layer by a plasma process. The simulation calculates a flux of particles impacting a feature and determines whether the etched pattern substantially conforms to the target pattern.
