Abstract
A semiconductor component having a material-reinforced contact area formed of a metal layer is disclosed. The contact area is jointly formed by a second metal area of a first metal layer and a fourth metal area of a second metal layer which is to be contacted. A thickness of the contact area material is at least twice that of a single metal layer and thereby prevents penetrative etching when a hole is created for contacting the metal layer.
