Early litho pathfinding, process optimization and analysis
S-Litho represents advanced lithography simulation for semiconductor device manufacturing process development and optimization. It covers a wide range of applications in proximity printing, optical, immersion, extreme ultraviolet (EUV), and electron beam (e-beam) lithography. Process-limiting effects within the imaging system of an exposure tool can be thoroughly analyzed, taking the impact of mask and substrate topography on photoresist patterning into account. Interfacing S-Litho with Synopsys TCAD tools allows a seamless modeling of complex integration techniques such as double-patterning. The link between S-Litho and Synopsys Proteus mask synthesis applications accelerates the generation and validation of optical proximity correction (OPC) models and improves process robustness.
