Patent ID: 8840797

Claim:
A method for producing a multilayer ceramic structure using a first green film that contains a ceramic material, comprising the following steps: (a) producing at least one porous region in the first green film, said at least one porous region extending from the surface of the first green film; (b) applying a first layer, in sections, to the surface of the first green film, wherein one section of the first layer is located above the at least one porous region produced in step (a); (c) positioning at least one additional green film on the surface of the first green film, to which the first layer has been applied; (d) laminating the first green film and the at least one additional green film to form a green film composite; and (e) sintering the green film composite, wherein during sintering material of the first layer becomes liquid or softens and substantially fills the at least one porous region in the first green film forming at least one hollow cavity in the at least one additional green film of the green film composite.
