Abstract
In an embodiment a substrate includes a ceramic main body including 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, and wherein some of the first volume regions terminate the substrate in a stacking direction.
