Abstract
The invention relates to a semiconductor device with a substrate, with at least one isolation layer with at least one window, with a passivation layer scheme lying on the isolation layer and a metallization lying on the passivation layer scheme, the latter comprising at least two dielectric layers of which the first dielectric layer covers the isolation layer with its edges as well as the substrate in an outer edge zone of the window, and of which the second dielectric layer covers the first dielectric layer also over the edge of the isolation layer and in a portion of the outer region of the window.
