Abstract
A substrate includes a ceramic layer, a metal layer fixed in a planar manner on a surface side of the ceramic layer and a cutout arranged in an edge region of the metal layer. The cutout in the edge region codes information. A multiple substrate having a plurality of these substrates is also provided, as is a method for producing the substrate.
Claims19
A substrate, comprising:
- a ceramic layer;
- a metal layer fixed in a planar manner on a surface side of the ceramic layer;
- and
- a cutout arranged in an edge region of the metal layer,
- wherein the cutout in the edge region codes information.

A multiple substrate, comprising:
- a ceramic layer which forms at least two individual substrates which are adjacent to one another and integrally connected to one another and which are delimited from one another by at least one cutting line running between the at least two individual substrates,
- wherein each of the at least two individual substrates comprises a ceramic layer, a metal layer fixed in a planar manner on a surface side of the ceramic layer, and a cutout arranged in an edge region of the metal layer, the cutout in the edge region coding information.
A method for producing a substrate, the method comprising:
- providing a ceramic layer;
- fixing a metal layer in a planar manner on a surface side of the ceramic layer;
- and
- forming a cutout in an edge region of the metal layer in such a way that the cutout in the edge region codes information.
