20120181874 | Semiconductor Device and Method of Manufacture Thereof - A semiconductor device, a method of manufacturing a semiconductor device and a method for transmitting a signal are disclosed. In accordance with an embodiment of the present invention, the semiconductor device comprises a first semiconductor chip comprising a first coil, a second semiconductor chip comprising a second coil inductively coupled to the first coil, and an isolating intermediate layer between the first semiconductor chip and the second semiconductor chip. | 07-19-2012 |
20120289023 | Method for Producing a Semiconductor Device - A method for producing a semiconductor device having a sidewall insulation includes providing a semiconductor body having a first side and a second side lying opposite the first side. At least one first trench is at least partly filled with insulation material proceeding from the first side in the direction toward the second side into the semiconductor body. The at least one first trench is produced between a first semiconductor body region for a first semiconductor device and a second semiconductor body region for a second semiconductor device. An isolating trench extends from the first side of the semiconductor body in the direction toward the second side of the semiconductor body between the first and second semiconductor body regions in such a way that at least part of the insulation material of the first trench adjoins at least a sidewall of the isolating trench. The second side of the semiconductor body is partly removed as far as the isolating trench. | 11-15-2012 |

20120289047 | Method for Producing a Connection Region on a Side Wall of a Semiconductor Body - A method for producing a connection region on a side wall of a semiconductor body is disclosed. A first trench is produced on a first surface of a semiconductor body and extends into the semiconductor body. An insulation layer is formed on the side walls and on the bottom of the first trench, and the first trench is only partially filled. The unfilled part of the first trench is filled with an electrically conductive material. A separating trench is produced along the first trench in such a way that a side wall of the separating trench directly adjoins the first trench. The part of the insulation layer which adjoins the separating trench is at least partially removed, with the result that at least some of the electrically conductive material in the first trench is exposed. | 11-15-2012 |
