S-Litho
Predictive Modeling of Lithographic Processes
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 Sentaurus Topography allows a seamless modeling of complex integration techniques such as double-patterning. The link between S-Litho and other Synopsys tools in the area of design and mask synthesis accelerates the generation of optical proximity correction (OPC) models, and helps to minimize process sensitivity.
