Patent ID: 7631289

Claim:
A method of generating a lithography model implemented with a processor, comprising: (a) determining a desired accuracy level for the lithography model; (b) determining a desired resolution level for the lithography model; (c) identifying a starting coarse grid size for a grid size to calculate the lithography model; (d) identifying a starting value for a number of matrices to use to calculate the lithography model; (e) calculating the lithography model based upon the grid size and the number of matrices; (f) determining if the lithography model corresponds to an acceptable resolution; (g) if the lithography model does not correspond to an acceptable resolution, then increasing the size of the grid size and reducing the number of matrices; (h) iterating from (e) to (g) until and acceptable resolution level is achieved for the lithography model; and (i) storing the lithography model in a computer usable medium.
