Abstract
In an embodiment a method for producing a substrate includes forming a green sheet stack including first green sheets and second green sheets, wherein each of the first green sheets and the second green sheets contains a ceramic material as a main component, and wherein the second green sheets further contain a sintering aid in addition to the ceramic material.
Claims8
A substrate comprising:
- a ceramic main body having first volume regions and second volume regions, each of the first volume regions and the second volume regions containing a ceramic material,
- wherein the first volume regions contain less sintering aid than the second volume regions,
- wherein the ceramic main body has contact areas configured for mounting components on the substrate, and/or integrated redistribution traces, and/or vias, and
- wherein the integrated redistribution traces comprises tungsten.
