摘要
Disclosed herein are correcting methods and devices for lithography hotspots of the post-routing layout, used for correcting lithography hotspots detected in the post-routing layout. At least one two-dimensional pattern of changeable size or position of the number of hotspots in the local area is selected and adjusted, so that the simulation value of the aerial image intensity of various local areas is optimized. The simulation value of the aerial image intensity is derived through calculation with respect to a set of optical simulation model cells that can be determined by the numerical value of distribution of the aerial image intensity of a number of basic two-dimensional patterns. After adjustment, the aerial image intensity of the local area can be calculated with respect to a set of optical simulation model cells, and a number of cells in the simulation model cells are selected to synthesize the two-dimensional pattern after the change.
