WebCalibre Computational Lithography The insatiable demand for integrated circuits (ICs) continues to drive smaller critical dimensions. Photolithography processes, including extreme ultraviolet (EUV), present ever more complexity and data volume. Our computational lithography solutions enable cost-effective technology enablement. WebThe described phenomena and examples have demonstrated that 3D mask effects need to be considered in the design of EUV systems and in OPC algorithms for EUV lithography. The combination of asymmetric illumination and 3D masks introduces an orientation dependency of the size and position of the printed features and significant contrast losses.
