Abstract

A bonding contact area on a semiconductor substrate is provided that includes a reinforcing structure having at least one conductive material layer arranged on the semiconductor substrate to receive the patterned reinforcing structure, a metal layer formed as a bonding contact layer with a bonding surface and arranged on a conductive material layer. Whereby, below the bonding surface, an oxide layer having at least about a 2 μm thickness is arranged, which extends beyond the edge of the bonding surface. The reinforcing structure is arranged in the oxide layer, when viewed looking down onto the bonding surface, outside the bonding surface within the oxide layer.
