摘要： A method of manufacturing an optical component comprising a substrate and a mounting frame with plural contact portions disposed at predetermined distances from each other is provided. The method comprises providing a measuring frame separate from the mounting frame for mounting the substrate, which measuring frame comprises a number of contact portions equal to a number of the contact portions of the mounting frame, wherein respective distances between the contact portions of the measuring frame are substantially equal to the corresponding distances between those of the mounting frame, measuring a shape of the optical surface of the substrate, while the substrate is mounted on the measuring frame, and mounting the substrate on the mounting frame such that the contact portions of the mounting frame are attached to the substrate at regions which are substantially the same as contact regions at which the substrate was attached to the measuring frame.

摘要： A projection objective for imaging a pattern arranged in an object surface of the projection objective into an image surface of the projection objective with a demagnified imaging scale has a plurality of optical elements which are arranged along an optical axis of the projection objective and are configured so that a defined image field curvature of the projection objective is set such that an object surface that is curved convexly with respect to the projection objective is imaged into a planar image surface. Such projection objective, with a suitable setting of the object surface curvature, avoids the disturbing effect on the image quality that would otherwise result from gravitation-dictated bending of a mask.

摘要： A method of optimizing lithographic processing to achieve substrate uniformity, is presented herein. In one embodiment, The method includes deriving hyper-sampled correlation information indicative of photoresist behavior for a plurality of wafer substrates processed at pre-specified target processing conditions. The derivation includes micro-exposing subfields of the substrates with a pattern, processing the substrates at the various target conditions, determining photoresist-related characteristics of the subfields (e.g., Bossung curvatures), and extracting correlation information regarding the subfield characteristics and the different target processing conditions to relate the target conditions as a function of subfield characteristics. The method then detects non-uniformities in a micro-exposed subsequent substrate processed under production-level processing conditions and exploits the correlation information to adjust the production-level conditions and achieve uniformity across the substrate.

摘要： A process of obtaining short-range flare model parameters representing a short-range flare which degrades a contrast of an image generated by a lithography tool, is disclosed. Short-range flare is measured from the image to obtain measured short-range flare data. A simulation is performed based on short-range flare model parameters to obtain simulated short-range flare data. The simulated short-range flare data is compared with the measured short range flare data. It is determined whether the short-range flare model parameters used in the simulation is appropriate based on the comparison result. The short-range flare model parameters is optimized according to the measured short-range data and the simulated short-range flare data if the short-range flare model parameters used for the simulation is not appropriate.

摘要： In order to optimize the image properties of several optical elements of which at least one is moved relative to at least one stationary optical element, the overall image defect resulting from the interaction of all optical elements is first of all measured. This is represented as a linear combination of the base functions of an orthogonal function set. The movable element is then moved to a new measurement position and the overall image defect is measured once again. After the linear combination representation of the new overall image defect, the image defects of the movable element and of the stationary element are calculated from the data thereby obtained. With only one movable optical element a target position in which the overall image defect is minimized can be directly calculated and adjusted there from. If several movable optical elements are available, methods are given for the efficient determination of the respective target position.
