System and method for compact model algorithms to accurately account for
effects of layout-induced changes in nitride liner stress in
semiconductor devices. The layout-sensitive compact model algorithms
account for the impact of large layout variation on circuits by
implementing algorithms for obtaining the correct stress response
approximations and layout extraction algorithms for obtaining the correct
geometric parameters that drive the stress response. In particular, these
algorithms include specific information from search "buckets" that are
directionally-oriented and include directionally-specific distance
measurements for analyzing in detail the specific shape neighborhood of
the semiconductor device. The algorithms are additionally adapted to
enable the modeling and stress impact determination of a device having
single stress liner film and dual-stress liners (two different liner
films that abut at an interface).
