Abstract: A super junction semiconductor device includes a semiconductor portion with parallel first and second surfaces. An impurity layer of a first conductivity type is formed in the semiconductor portion. Between the first surface and the impurity layer a super junction structure includes first columns of the first conductivity type and second columns of a second conductivity type. A sign of a compensation rate between the first and second columns may change along a vertical extension of the columns perpendicular to the first surface. A body zone of the second conductivity type is formed between the first surface and one of the second columns. A field extension zone of the second conductivity type may be electrically connected to the body zone or a field extension zone of the first conductivity type may be connected to the impurity layer. The field extension zone improves the avalanche characteristics of the semiconductor device.

Abstract: In a semiconductor substrate with a first surface and a working surface parallel to the first surface, columnar first and second super junction regions of a first and a second conductivity type are formed. The first and second super junction regions extend in a direction perpendicular to the first surface and form a super junction structure. The semiconductor portion is thinned such that, after the thinning, a distance between the first super junction regions having the second conductivity type and a second surface obtained from the working surface does not exceed 30 ?m. Impurities are implanted into the second surface to form one or more implanted zones. The embodiments combine super junction approaches with backside implants enabled by thin wafer technology.

Abstract: A super junction semiconductor device includes a semiconductor portion with a first surface and a parallel second surface. A doped layer of a first conductivity type is formed at least in a cell area. Columnar first super junction regions of a second, opposite conductivity type extend in a direction perpendicular to the first surface. Columnar second super junction regions of the first conductivity type separate the first super junction regions from each other. The first and second super junction regions form a super junction structure between the first surface and the doped layer. A distance between the first super junction regions and the second surface does not exceed 30 ?m. The on-state or forward resistance of low-voltage devices rated for reverse breakdown voltages below 1000 V can be defined by the resistance of the super junction structure.

Abstract: A semiconductor device includes a semiconductor layer with a super junction structure including first columns of a first conductivity type and second columns of a second conductivity type opposite the first conductivity type. The super junction structure is formed in a cell area and in an inner portion of an edge area surrounding the cell area. In the inner portion of the edge area a reverse blocking capability is locally reduced by a local modification of the semiconductor layer. The local modification allows an electric field to extend in case an avalanche breakdown occurs. The reverse blocking capability is locally reduced in the edge area, wherein once an avalanche breakdown has been triggered the semiconductor device accommodates a higher reverse voltage. Avalanche ruggedness is improved.

Abstract: The disclosed invention provides a structure and method for providing a high lateral voltage resistance between the electrical networks, sharing a lateral plane, of conductive elements (e.g., having different high voltage potentials) comprising a coupler.

The structure therefore provides a galvanically isolated integrated coupler which avoids electrical shorting between circuits (e.g.
