Title: The Innovative Contributions of Roger McCleary
Introduction
Roger McCleary is an accomplished inventor based in Salem, NH (US). He is known for his significant contributions to the field of projection systems and metrology. With a focus on enhancing the accuracy and flexibility of production images, McCleary has made strides in addressing challenges related to misalignment and aberration.
Latest Patents
McCleary holds a patent for a "System Metrology Core," which introduces projection systems and methods featuring mechanically decoupled metrology plates. This innovative approach allows for the characterization and compensation of misalignment and aberration in production images caused by thermal and mechanical effects. The sensors on the metrology plate measure its position relative to the image and substrate during exposure. The data collected from these sensors are utilized to dynamically adjust the projection optics and substrate, effectively correcting alignment errors and aberration-induced discrepancies. Compared to previous systems, McCleary's methods offer enhanced design flexibility and reduced constraints on mechanical stability and thermal expansion. Additionally, the decoupled metrology plates enable simultaneous and independent alignment of multiple objectives.
