Ceramic-metal substrate, particularly multiple substrate

摘要

The substrate has a ceramic plate or layer (2) forming two adjoining substrate regions provided with respective metal surfaces (3',4'). At least one metal surface (3',4') of the substrate regions has at least one edge reduction (10a) on an edge adjacent to and extending along a break-off line. The shape of the edge reduction is such that the quantity of metal per unit volume (specific metal quantity) is reduced by 10 to 80 per cent compared to the metal surfaces outside the edge reduction.
