A method for generating a write pattern to be used in a maskless-lithography process is described. During the method, a computer system determines a one-to-one correspondence between pixels in the write pattern and at least a subset of elements in a spatial-light modulator used in the maskless-lithography process. Furthermore, the computer system generates the write pattern. Note that the write pattern includes features corresponding to at least the subset of elements in the spatial-light modulator, and the generating is in accordance with a characteristic dimension of an element in the spatial-light modulator and a target pattern that is to be printed on a semiconductor wafer during the maskless-lithography process.

Write-pattern determination for maskless lithography

A method for determining mask patterns to be used on photo-masks in a multiple-exposure photolithographic process is described. During the method, an initial mask pattern, which is intended for use in a single-exposure photolithographic process, and a target pattern that is to be printed are used to determine a first mask pattern and a second mask pattern, which are intended for use in the multiple-exposure photolithographic process. In particular, the first mask pattern includes a first feature and the second mask pattern includes a second feature, and the first feature and the second feature overlap an intersection between features in the initial mask pattern. Moreover, the first mask pattern and the second mask pattern have at least one decreased spatial frequency relative to the initial mask pattern along at least one direction in the initial mask pattern.
