PROCESS AND APPARATUS FOR THE PLANARIZING OF ROUGH, STRUCTURED OR HETEROGENEOUS SURFACES

摘要

A process and an apparatus for the planarizing of rough, structured or heterogeneous surfaces with a leveling layer. A cover layer permeable to energy radiation is laminated by means of a film pressing device, which comprises a sliding shoe and a feed device, on to a substrate base bearing the surface to be planarized. During lamination, the contact zone between the film pressing device and the substrate base forms a tapering laminating nip, which is constantly supplied with the organic coating material forming a film or layer.
