Abstract:
1. A computer-implemented method for mask optimization for a layout design comprising: generating, by using a processor, a first list of critical areas based at least in part upon a cross domain correlation, wherein the cross domain correlation comprises correlating simulated critical areas caused by different types of effects from one or more different design based analysis tools with weighing factors from a manufacturer, wherein the weighing factors are tuned to adjust locations of the simulated critical areas of the different types of effects such that locations of the simulated critical areas determined by the one or more different design based analysis tools correspond to locations of actual critical areas determined from actual manufactured data; filtering the weighing factors of the different types of effects for the mask optimization to provide one or more filtered weighing factors for tuning critical areas of the layout design for the mask optimization; applying a priority for the mask optimization for the critical areas of the layout design, wherein the priority is determined based at least in part upon the filtered weighing factors; providing mask optimizing treatment on a mask design for the first list of the critical areas of the layout design based at least in part upon the priority; and displaying the mask design on a display device or storing the mask design in a volatile or non-volatile computer readable medium.
