    摘要: One illustrative method disclosed herein involves identifying an overall target pattern comprised of at least one hole-type feature, decomposing the overall target pattern into at least a first sub-target pattern and a second sub-target pattern, wherein the first sub-target pattern and the second sub-target pattern each comprise at least one common hole-type feature, generating a first set of mask data information corresponding to the first sub-target pattern, and generating a second set of mask data information corresponding to the second sub-target pattern.

    摘要: Disclosed herein are various OPC methods as it relates to the formation of masks to be used in multiple patterning processes, such as double patterning processes, and to the use of such masks during the manufacture of semiconductor devices. One illustrative method disclosed herein includes the steps of decomposing an initial overall target pattern into at least a first sub-target pattern and a second sub-target pattern, wherein each of the first and second sub-target patterns comprise at least one feature, and performing a first optical proximity correction process on the first sub-target pattern, wherein a position of at least one feature of the second sub-target pattern in the initial overall target pattern is considered when performing the first optical proximity correction process.
