Abstract (en)

[origin: WO0004577A1] According to the invention, a ceramic body with a monolithic multi-layer structure is produced using a multistage sintering process. To prevent lateral shrinkage the body is built up of green films whose material becomes compacted at different temperature intervals. In this way a body having a very low component tolerance is obtained. A plurality of different passive electronic components can be integrated into the volume of the body. Such a body is used, for example, as substrate of a microwave module.
