Abstract
Aspects of the invention relate to techniques for improving speed and consistency of OPC processes based on pattern matching. Pattern matching may be performed on a layout design to determine one or more arrays in the layout design that comprise arrays of identical layout patterns of which each matches a reference pattern. The one or more arrays may then be partitioned into core portions and boundary portions. The OPC process information for the reference pattern may be applied to the core portions, while a conventional OPC process may be performed on the boundary portions and layout regions outside of the one or more arrays.
