    摘要: A method for the exposure of image points of a photosensitive layer comprising a photosensitive material on a substrate by means of an optical system. The method including continuously moving the image points with respect to the optical system; and controlling a plurality of secondary beams by means of the optical system individually for individual exposures of each image point, whereby the secondary beams are put either into an ON state or into an OFF state, wherein a) secondary beams in the ON state produce an individual exposure of the image point assigned to the respective secondary beam and b) secondary beams in the OFF state do not produce any individual exposure of the image point assigned to the respective secondary beam; wherein, for the generation of image points with grey tones n>1, individual exposures are carried out by different secondary beams with individual doses D.

    摘要: A method and apparatus for embossing micro-structures and/or nano-structures. The method includes the steps of providing a structured embossing roll having end faces; coupling a crosslinking radiation into the structured embossing roll which is transparent for the crosslinking radiation, wherein the embossing roll functions as a light guide for the coupled in crosslinking radiation; providing a carrier having an embossing compound applied thereto; contacting the embossing roll with the embossing compound; coupling the crosslinking radiation out of the embossing roll; and curing the embossing compound which has been acted upon by the coupled out crosslinking radiation via the embossing roll.

    摘要: A metrology device includes a sound sample holder and an optical system. The sound sample holder is provided for applying sound waves to a first substrate stack surface of the substrate stack. The optical system include a source, a lens field, a beam splitter, and a detector. The source is provided for outputting electromagnetic radiation, which is split into at least one first beam path and one second beam path. The lens field is provided for applying the first beam path to a substrate stack measuring surface of the substrate stack. The beam splitter is provided for forming an interference radiation made up of the first and second beam paths of the electromagnetic radiation. The detector is provided for detecting the interference radiation.
