Abstract
The invention relates to a method for the generation of raised and/or recessed structures on workpieces comprising the steps: applying a pressure difference between one side of a wall of the workpiece and another side substantially opposite thereto; local heating of the wall of the workpiece to a softening temperature of the workpiece by a heat source in order to induce local deformation of the wall of the workpiece; and cooling of the workpiece. The invention relates, moreover, to an apparatus for carrying out this method.
