Xray lithography

X-ray lithography, is a process used in electronic industry to selectively remove parts of a thin film. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist, or simply "resist," on the substrate. A series of chemical treatments then engraves the produced pattern into the material underneath the photoresist.

  • FLASH observes exploding xenon nanoparticles

    With the bright X-ray flashes from FLASH the scientists made xenon clusters explode. The same flash allowed the researchers to record the structure of the cluster just before the explosion (top). With an ion spectrometer the scientists recorded the debris from the explosion (below). Credit: Daniela Rupp/Technical University of Berlin

  • HI4PI: A new all-sky survey of neutral hydrogen

    Two of the world's largest fully steerable radio telescopes, the 100-m dish at Effelsberg/Germany and the 64-m Parkes/Australia telescope, mapped the detailed structure of neutral hydrogen across the Northern and Southern hemispheres. Today, the complete survey, HI4PI, is released to the scientific community. It discloses a wealth of fine details of the large scale structure of the Milky Way's gas distribution. HI4PI is the product of a joined effort of astronomers of many countries and will be a mile stone for the decades to come.
