Extreme ultraviolet (EUV) radiation is a key technology for material science, attosecond metrology, and lithography. Here, we experimentally demonstrate metasurfaces as a superior way to focus EUV light. These devices exploit the fact that holes in a silicon membrane have a considerably larger refractive index than the surrounding ...

Interference lithography (or holographic lithography) is a technique for patterning regular arrays of fine features, without the use of complex optical systems or photomasks. Meer weergeven The basic principle is the same as in interferometry or holography. An interference pattern between two or more coherent light waves is set up and recorded in a recording layer (photoresist). This interference … Meer weergeven The technique is readily extendible to electron waves as well, as demonstrated by the practice of electron holography. Spacings of … Meer weergeven The interference of atomic de Broglie waves is also possible provided one can obtain coherent beams of cooled atoms. The momentum of an atom is even larger than for … Meer weergeven • Large-area patterning using interference and nanoimprint lithography • Interference lithography at Fraunhofer ISE Meer weergeven For interference lithography to be successful, coherence requirements must be met. First, a spatially coherent light source must be used. This is effectively a point light … Meer weergeven Coherent light must be split into two or more beams prior to being recombined in order to achieve interference. Typical methods for beam splitting are Lloyd´s mirrors Meer weergeven The benefit of using interference lithography is the quick generation of dense features over a wide area without loss of focus. Seamless diffraction gratings on areas of more than one square meter have been originated by interference lithography. … Meer weergeven WebAn interference pattern between two or more coherent light waves is set up and recorded in a recording layer ( photoresist ). This interference pattern consists of a periodic series of fringes representing intensity minima and maxima. Upon post-exposure photolithographic processing, a photoresist pattern corresponding to the periodic intensity ...
