Abstract:
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.

Claim (Index 2):
A monitoring device for monitoring an arrangement of movable reflective optical elements, the device comprising:\n a measurement illumination apparatus configured to emit measuring light and direct the measurement light towards the arrangement of moveable reflective optical elements; a lens having a focal plane; a light detector arranged at least substantially in the focal plane of the lens, wherein the lens is configured to direct measuring light reflected from moveable reflective optical elements of the arrangement of moveable reflective optical elements to the light detector; and an evaluation device coupled to the detector and configured to provide information about an alignment of one or more of the reflective optical elements based on a signal from the light detector, wherein the arrangement of movable reflective optical elements is part of an illumination system of a microlithography tool.
