Lithographic system, device manufacturing method, setpoint data optimization method, and apparatus for producing optimized setpoint data

摘要

An iterative method of producing optimized setpoint data for controlling the actuation of elements of an array of individually controllable elements in a maskless system and systems therefore. The optimization is based on estimation of a device structure that can utilizes one or more of the following factors: the low-pass characteristics of the projection system, the configuration of the illumination system, and the process window properties.
