Abstract
In this paper we discuss the EUV OPC modeling challenges and potential solutions, as well as OPC integration requirements to support the forthcoming application of EUV lithography. 10-nm-node OPC modeling is considered as an example. Wafer and mask process data were collected for calibration and verification patterns, to understand the mask making error/OPC model interactions. Several factors, including compact mask topography modeling impact, were analyzed by means of rigorous simulations and model fitting. This was performed on a large-scale data set, to ensure accurate characterization of the OPC modeling strategies, using a large number of patterns.
