摘要:
A method for producing a connection electrode for a first and second adjacent and complementarily doped semiconductor zones includes a step of producing a trench extending through the first semiconductor zone into the second semiconductor zone in such a way that the first semiconductor zone is uncovered at sidewalls of the trench and the second semiconductor zone is uncovered at least at a bottom of the trench. The method also includes producing a first connection zone in the first semiconductor zone by implanting dopant atoms into the sidewalls at least at a first angle. The method further includes producing a second connection zone in the second semiconductor zone by implanting dopant atoms at least at a second, different angle. The method also includes depositing an electrode layer at least onto the sidewalls and the bottom of the trench for the purpose of producing the connection electrode.

A method for producing a connection electrode for a first semiconductor zone and a second semiconductor zone includes producing a trench extending through the first semiconductor zone right into the second semiconductor zone in such a way that the first semiconductor zone is uncovered at sidewalls of the trench and the second semiconductor zone is uncovered at least at a bottom of the trench. The method also includes applying a protective layer to a first one of the first and second semiconductor zones in the trench, and producing a first connection zone in the second of the two semiconductor zones, which is not covered by the protective layer. The method further includes depositing an electrode layer at least onto the sidewalls and the bottom of the trench for the purpose of producing the connection electrode.

According to one embodiment, a method for manufacturing a semiconductor device includes forming trenches in a first side of a semiconductor material and forming a thick oxide layer on the trenches and on the first side. A part of the first side and the trenches is masked using a first mask, and the semiconductor material is doped by implantation through the thick oxide layer while the first mask is present. At least part of the thick oxide layer is removed while the first mask remains.

摘要:
A semiconductor component comprises a semiconductor body with at least one protective trench in the semiconductor body. An insulation layer is situated at least at the bottom of the protective trench. An electrically conductive layer having a thickness D is formed on the insulation layer in the protective trench, wherein the electrically conductive layer only partly fills the protective trench.
