Abstract:
1. A semiconductor device with a semiconductor body, comprising: a front-sided surface; an active cell region including a semiconductor device structure; and an edge region surrounding the active cell region; wherein a layer on the front-sided surface includes a passivation layer over the edge region and over the active cell region, the passivation layer including a semiconducting insulation layer of a semiconducting material, a bandgap of the semiconducting insulation layer being greater than a bandgap of the material of the semiconductor body, wherein a conducting layer is arranged at least partially on the semiconducting insulation layer, wherein a further layer is arranged at least partially between the semiconducting insulation layer and the conducting layer, wherein the further layer includes a silicate glass, selected from the group of boron phosphorous silicate glasses, boron silicate glasses and of the undoped silicate glasses, and wherein the semiconducting material of the semiconducting insulation layer includes silicon-doped amorphous carbon.
