摘要： Various implementations of the invention provide for the optimization of etch induced pattern transfer across a significant portion of a design. In various implementations, an entire design, that is a “full-chip” may be optimized. With some implementations, the invention may be employed to detect etch hotspots. Further implementations may be employed in either or both a mask data preparation process (“MDP”) or to determine the etch effects of including various patterns in a design.

摘要： A system and method for optimizing an illumination source to print a desired pattern of features dividing a light source into pixels and determining an optimum intensity for each pixel such that when the pixels are simultaneously illuminated, the error in a printed pattern of features is minimized. In one embodiment, pixel solutions are constrained from solutions that are bright, continuous, and smooth. In another embodiment, the light source optimization and resolution enhancement technique(s) are iteratively performed to minimize errors in a printed pattern of features.

摘要： Methods for approximating simulated contours are provided herein. With some implementations, a function that incorporates a Gaussian proximity kernel to approximate the electron beam exposure effects is used to simulate a printed image. Subsequently, one or more corners of the simulated printed image may be approximated by two or more straight edges. In various implementations, the number of straight edges used to approximate the corner as well as the orientation of the one or more straight edges is determined based upon the characteristics of the corner, such as, the corner having an obtuse angle larger than 135 degrees for example. With various implementations, two straight edges are used to approximate the corner, the orientation of the two straight edges being determined by a first point, a second point, and a shared corner point.
