    Abstract: A reverse-conducting insulated gate bipolar transistor includes a wafer of first conductivity type with a second layer of a second conductivity type and a third layer of the first conductivity type. A fifth electrically insulating layer partially covers these layers. An electrically conductive fourth layer is electrically insulated from the wafer by the fifth layer. The third through the fifth layers form a first opening above the second layer. A sixth layer of the second conductivity type and a seventh layer of the first conductivity type are arranged alternately in a plane on a second side of the wafer. A ninth layer is formed by implantation of ions through the first opening using the fourth and fifth layers as a first mask.

    Abstract: A method of manufacturing a power semiconductor device is provided. A first oxide layer is produced on a first main side of a substrate of a first conductivity type. A structured gate electrode layer with at least one opening is then formed on the first main side on top of the first oxide layer. A first dopant of the first conductivity type is implanted into the substrate on the first main side using the structured gate electrode layer as a mask, and the first dopant is diffused into the substrate. A second dopant of a second conductivity type is then implanted into the substrate on the first main side, and the second dopant is diffused into the substrate. After diffusing the first dopant into the substrate and before implanting the second dopant into the substrate, the first oxide layer is partially removed. The structured gate electrode layer can be used as a mask for implanting the second dopant.

    Abstract: An n-channel insulated gate semiconductor device with an active cell (5) comprising a p channel well region (6) surrounded by an n type third layer (8), the device further comprising additional well regions (11) formed adjacent to the channel well region (6) outside the active semiconductor cell (5) has enhanced safe operating are capability. The additional well regions (11) outside the active cell (5) do not affect the active cell design in terms of cell pitch, i.e. the design rules for cell spacing, and hole drainage between the cells, hence resulting in optimum carrier profile at the emitter side for low on-state losses.
