20090073413Write-Pattern Determination for Maskless Lithography - 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.03-19-2009

20100021042Photo-Mask and Wafer Image Reconstruction - A system receives a mask pattern and a first image of at least a portion of a photo-mask corresponding to the mask pattern. The system determines a second image of at least the portion of the photo-mask based on the first image and the mask pattern. This second image is characterized by additional spatial frequencies than the first image.01-28-2010
