    摘要: A method of manufacturing an optical system having plural optical elements mounted relative to each other on a mounting structure of the optical system comprises disposing the optical system in a beam path of an interferometer apparatus having an interferometer optics and a selectable hologram for shaping a beam of measuring light to be incident on surfaces of the optical elements of the optical system; selecting a first hologram of the interferometer apparatus and recording at least one first interference pattern generated by measuring light reflected from a surface of a first optical element; selecting a second hologram of the interferometer apparatus, wherein the second hologram is different from the first hologram, and recording at least one second interference pattern generated by measuring light reflected from a surface of a second optical element, which is different from the first optical element; and adjusting a position of the first optical element relative to the second optical element on the mounting structure based upon the first interference pattern and the second interference pattern.

    摘要: A lithography method is proposed employing a projection exposure system having a catoptric imaging optics comprising a mirror formed as phase mask in the imaging beam path, wherein the mirror formed as phase mask exhibits continuous regions having dielectric layers provided thereon. Optionally, the regions of the mirror formed as phase mask are configured such that an axial extension of an image of a point (DOF) of the imaging is increased or/and a lateral extension of an image of a point of the imaging is decreased. Preferably multiple exposures of a same radiation sensitive substrate are performed in order to achieve an increase in resolution and scaling down of the manufacturing trace structures (61, 61′), respectively.

    摘要: A projection exposure system and method of manufacturing a miniaturized device using the projecting exposure system uses an imaging of a patterning structure onto a substrate using a projection optical system. Measuring light is directed through the projection optical system to be incident on the substrate and measuring light reflected from the substrate is superimposed with reference light to generate an interference pattern. The interference pattern is analyzed to determine imaging properties of the projecting optical system. Actuators of the projection optical system may be used to improve the imaging characteristics.

    摘要: An optical system, such as a microlithographic projection exposure apparatus, includes a first optical component, a second optical component, and a measurement arrangement for determining the relative position of the first optical component and the second optical component in six degrees of freedom. The measurement arrangement is adapted to determine the relative position of the first optical component and the second optical component over six different length measurement sections. The length measurement sections extend directly between the first optical component and the second optical component.
