    摘要: The invention relates to a process for evaporating a liquid containing vaporizable oxidation-sensitive compounds in an evaporator in which the liquid is brought into contact with a heated solid surface for evaporation, by a process in which direct contact between the resulting vapor phase and the heated solid surface is substantially avoided. It also directed to an evaporator composed of a heatable solid surface (16), an apparatus (2, 3) for heating the solid surface and an apparatus (10) for feeding a liquid containing vaporizable compounds to the heatable solid surface, wherein the apparatus for feeding the liquid is designed and arranged in the evaporator in such a way (12, 14, 18) that direct contact between a resulting vapor phase and the heatable solid surface is substantially avoided.

    摘要: The invention relates to a method of producing microstructured metallic bodies in which plastic negative molds of the microstructures are produced on an electrically conductive base plate by means of electron beam lithography, X-ray lithography or a micromolding technique. Cavities of the negative molds are filled with metal by electroplating while employing the electrically conductive base plate as an electrode. In the course of producing the negative molds, a residual plastic layer is left at the bottom of the cavities of the negative molds on the electrically conductive base plate. Also, before the cavities of the negative molds are filled with metal by electroplating, the residual plastic layer at the bottom of the cavities is removed by means of reactive ion etching with ions that are accelerated perpendicularly toward the surface of the base plate.
