Latest Patents

One of Yenikaya's latest patents is titled "Full-chip hierarchical inverse lithography." This invention relates to an inverse lithography technology (ILT) solution that provides masks with perfect symmetry and minimal complexity. The methodology includes several steps that strictly maintain symmetry throughout the process. In one step, lithographic model kernels are processed to enforce symmetry corresponding to an illumination source. In another step, an ideal grayscale mask for a target pattern is computed using the symmetrical model kernels and a computation domain centered on each target polygon. Additionally, optimized polygons are computed using the computed grayscale mask. The final mask perfectly maintains the symmetry properties of the illumination source. This ILT solution can be applied to an original design hierarchy and on a full chip scale.

Another notable patent is "Apparatus and method for segmenting edges for optical proximity correction." This invention involves an apparatus and method for modifying a mask data set. It includes calculating a derivative of a figure-of-merit, indicative of a data set defined by a plurality of polygon edges, and then segmenting polygon edges in response to this calculation.
