  • Publication number: 20240310718
    Abstract: A method for generating a mask pattern for a lithographic process. The method involves generating a smoothed representation of a segmented mask pattern by applying a first smoothing function and adjusting the segmented mask pattern by with a set of changes to one or more of the plurality of segmented features. Further, a patterning process simulation is performed in an iterative manner by using the smoothed mask pattern of an adjusted segmented mask pattern until a termination condition is satisfied. In each iteration, upon adjusting the segmented mask pattern, a smoothed mask pattern is generated and used by process models to simulate the patterning process. Once the termination condition is satisfied, a resultant segmented mask pattern is obtained. Then, a final mask pattern is generated by applying a second smoothing function to a resultant segmented mask pattern.

  • Patent number: 9619607
    Abstract: Described herein is a method for obtaining a preferred layout for a lithographic process, the method comprising: identifying an initial layout including a plurality of features; and reconfiguring the features until a termination condition is satisfied, thereby obtaining the preferred layout; wherein the reconfiguring comprises evaluating a cost function that measures how a lithographic metric is affected by a set of changes to the features for a plurality of lithographic process conditions, and expanding the cost function into a series of terms at least some of which are functions of characteristics of the features.
