Abstract

The invention relates to the production of thin metal layers and structures thereof on substrates of various structures. The lateral extent of a metal layer on the respective substrate can be prescribed with a precision in the micron and submicron range. The method described makes it possible to manufacture flat and three-dimensional metal structures on smooth planar or curved surfaces, as are required, for example, for depicting writing or drawings. The method uses no printing techniques.
