Baerbel Schwaer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9164396
    Abstract: A microlithographic projection exposure apparatus comprises a projection objective which images an object onto an image plane and has a lens with a curved surface. In the projection objective there is a liquid or solid medium which directly adjoins the curved surface over a region which is usable for imaging the object. The projection exposure apparatus also has an adjustable manipulator for reducing an image field curvature which is caused by heating of the medium during the projection operation.

  • Patent number: 7990622
    Abstract: A projection objective of a microlithographic projection exposure apparatus comprises a manipulator for reducing rotationally asymmetric image errors. The manipulator in turn contains a lens, an optical element and an interspace formed between the lens and the optical element, which can be filled with a liquid. At least one actuator acting exclusively on the lens is furthermore provided, which can generate a rotationally asymmetric deformation of the lens.

  • Publication number: 20090141258
    Abstract: An imaging device in a projection exposure machine for microlithography includes at least one optical element and at least one manipulator, a linear drive for manipulating the position of the optical element. The linear drive has at least one moving element, the moving element having a shearing part and a lifting part. The shearing part is arranged to move the optical element and the lifting part is arranged to move the shearing part. The linear drive has a supporting element which is in contact with and prevents movement of the optical element while the shearing part is moved by the lifting part.
