Latest Patents
One of his latest patents is titled "Method and system for semiconductor design hierarchy analysis and transformation." This invention provides a method and apparatus for partitioning input designs into repeating patterns known as template cores. It facilitates design verification for manufacturability and design corrections for optical and process effects through hierarchy analysis. This analysis extracts cell overlap information and hierarchy statistics, ultimately identifying template core candidates. This innovation allows designs to be modified or analyzed effectively, especially when dealing with deep cell hierarchies and significant cell overlaps.
Another notable patent is "Correcting 3D effects in phase shifting masks using sub-resolution features." This invention improves printed feature resolution on wafers by utilizing phase shifting on masks. It addresses the intensity imbalance between 0-degree and 180-degree phase shifters, providing an improved method for designing alternating phase shift masks (PSM). By incorporating sub-resolution features, known as 'blockers,' into the design, the intensity associated with 0-degree phase shifters can be balanced with that of the 180-degree phase shifters. This innovation retains image contrast and ensures high-quality printed features.
