摘要： An illumination system for a microlithographic projection exposure apparatus includes a mirror arranged in a multi-mirror array and capable of being tilted via at least one actuator. The illumination system also includes drive electronics, which include a coarse digital-to-analogue converter with a first resolution, and a fine digital-to-analogue converter with a second resolution, and an adder. The second resolution is higher than the first resolution. The adder can add output quantities that are output by the two digital-to-analogue converters to yield an overall quantity that is capable of being applied at least indirectly to the at least one actuator of the mirror.

摘要： Microlithographic illumination system includes individually drivable elements to variably illuminate a pupil surface of the system. Each element deviates an incident light beam based on a control signal applied to the element. The system also includes an instrument to provide a measurement signal, and a model-based state estimator configured to compute, for each element, an estimated state vector based on the measurement signal. The estimated state vector represents: a deviation of a light beam caused by the element; and a time derivative of the deviation. The illumination system further includes a regulator configured to receive, for each element: a) the estimated state vector; and b) target values for: i) the deviation of the light beam caused by the deviating element; and ii) the time derivative of the deviation.

摘要： A micromirror of a micromirror array in an illumination system of a microlithographic projection exposure apparatus can be tilted through a respective tilt angle about two tilt axes. The micromirror is assigned three actuators which can respectively be driven by control signals in order to tilt the micromirror about the two tilt axes. Two control variables are specified, each of which is assigned to one tilt axis and which are both assigned to unperturbed tilt angles. For any desired combinations of the two control variables, as a function of the two control variables, one of the three actuators is selected and its control signal is set to a constant value, in particular zero. The control signals are determined so that, when the control signals are applied to the other two actuators, the micromirror adopts the unperturbed tilt angles as a function of the two control variables.

摘要： An illumination system of a microlithographic projection exposure apparatus has a pupil surface and an essentially flat arrangement of desirably individually drivable beam deviating elements for variable illumination of the pupil surface. Each beam deviating element allows deviation of a projection light beam incident on it to be achieved as a function of a control signal applied to the beam deviating element. A measurement illumination instrument directs a measurement light beam, independent of the projection light beams, onto a beam deviating element. A detector instrument records the measurement light beam after deviation by the beam deviating element. An evaluation unit determines the deviation of the projection light beam from measurement signals provided by the detector instrument.
