Abstract
A hybrid multi-step method for Sub-Resolution Assist Feature (SRAF) placement is presented. The process window, characterized by process variation bands (PV-bands), is subjected to optimization. By applying a state-of-the-art advanced pattern matching based approach, the SRAF placement is optimized to maximize the process window. Due to the complexity of building a complete Rule-Based SRAF (RBSRAF) solution and the performance limitation of the Model-Based SRAF solution (MBSRAF), the hybrid pattern based SRAF reduces the complexity and improves performance. In this paper, the hybrid pattern-based SRAF algorithm and its implementation, as well as testing results, are discussed with respect to process window and performance.
