Abstract (en)
[origin: WO2009092424A2] The invention relates to a semi-conductor structure, comprising an n metallization and a p metallization (7), and a semi-conductor substrate having an n-doped base region and a p-doped emitter region (2) adjoining the same at least partially for configuring an emitter/base p-n junction, wherein the emitter region (2) extends at least partially approximately parallel to an emitter surface (2b) of the semi-conductor substrate, and the n metallization is connected to the base region, and the p metallization (7) is connected to the emitter region (2) in an electrically conductive manner. It is essential to the invention that the semi-conductor structure further comprises an n-doped passivation region (5), which is disposed at least partially between the emitter surface (2b) and the emitter region 2, wherein the passivation region (5) is neither connected to the n metallization nor to the p metallization (7) in an electrically conductive manner. The invention further relates to a method for the production of such a semi-conductor structure.
