Latest Patents

Among his latest patents are two notable innovations:

1. **Sub-resolution assist feature implementation for shot generation** - This patent describes a design layout for a semiconductor chip that includes information on desired shapes to be fabricated. Clusters of photolithographic exposure 'shots' are generated and assessed for shot density to approximate a mask shape that produces the desired fabricated shapes during wafer fabrication. A simulation is conducted on these clusters to estimate the resulting fabrication shapes, which are then modified iteratively to align more closely with the desired shapes.

2. **Sub-resolution assist feature implementation with shot optimization** - Similar to the first, this patent also involves a design layout for a semiconductor chip. It details the generation of clusters of photolithographic exposure 'shots' and the iterative process of simulating and modifying these shots to achieve the desired fabrication shapes.
