  • Patent number: 11630394
    Abstract: Disclosed is a method for lithographically producing a target structure on a non-planar initial structure by exposing a photoresist by means of a lithography beam. In the inventive method, the topography of a surface of the non-planar initial structure is detected. A test parameter for the lithography beam is used and an interaction of the lithography beam with the initial structure and the resultant change in the lithography beam and/or the target structure to be produced are determined. A correction parameter for the lithography beam is determined such that the change in the lithography beam and/or the target structure to be produced that is caused by the interaction of the lithography beam with the initial structure is reduced. The desired target structure on the initial structure is produced by exposing the photoresist by means of the lithography beam using the correction parameter.

  • Patent number: 8890520
    Abstract: Nuclear magnetic resonance in a sample volume located in a measuring volume is examined by generating a packet of laser pulses to act on the measuring volume when a quasi-static magnetic field occurs therein. If the resonance conditions for nuclear spins contained therein are fulfilled, the sample volume emits a response signal that is received by a detector. The quasi-static magnetic field occurring within the measuring volume is generated by acting on the measuring volume with a low-frequency laser beam having a wavelength that exceeds the wavelength of the excitation laser by at least 102 to create a periodically variable magnetic field in the measuring volume. The amplitude of the field is at least 90% of the maximum thereof in the measuring volume. Alternatively, the measuring volume is acted on by a high-frequency laser beam having a frequency exceeding the frequency of the excitation laser by at least 102.
