Patent ID: 7642545

Claim:
A layer system, comprising: a silicon layer; and a passivating layer at least regionally and superficially deposited on the silicon layer, wherein the passivating layer has a substantially inorganic first partial layer and a substantially polymer second partial layer; wherein, within the passivating layer, at least regionally an intermediate layer situated between the first partial layer and the second partial layer and adjoining both the first and second partial layers is provided, wherein the intermediate layer has a composition such that in a surface area of the intermediate layer adjoining the first partial layer, the intermediate layer has a composition at least approximately similar to the first partial layer, and in a surface area of the intermediate layer adjoining the second partial layer, the intermediate layer has a composition at least approximately similar to the second partial layer, and wherein the intermediate layer transitions, one of continuously and in steps, from the composition at least approximately similar to the first partial layer to the composition at least approximately similar to the second partial layer.
