Abstract

The invention relates to a method for producing a component from ceramic materials in which a plurality of layers are applied to a base body by means of screen printing or template printing, said layers being formed from a ceramic material, in each case in a defined geometry above one another in the form of a paste or suspension in which powdery ceramic material and at least one binder are included. At least one region is formed here within at least one layer having a defined thickness and geometry composed of a further material that can be removed in a thermal treatment and that is likewise applied in the form of a paste or suspension by means of screen printing or template printing. Electrically functional structures composed of an electrically conductive or semiconductive material are applied to and/or formed on and/or in at least of the ceramic layers prior to the application of a further ceramic layer. The layer structure is then sintered in a thermal heat treatment, with the further material being removed and at least one hollow space being formed with defined dimensions of width, length, and height.
