Optimizing curvilinear OPC: Vector-based site and anchor decoupling

As semiconductor technology advances to sub-5 nm nodes, curvilinear mask features are essential for pattern fidelity but challenge traditional OPC methods. Siemens introduces an advanced vector-based site and anchor decoupling framework that independently and dynamically controls OPC fragmentation and optimization. This innovation significantly boosts process window robustness, speeds up mask recipe development and refines EPE management, delivering critical improvements for curvilinear photomask applications within Siemens EDA solutions.
