    摘要: A semiconductor device and production method is disclosed. In one embodiment, the semiconductor device includes a first electrode and a second electrode, located on surfaces of a semiconductor body, and an insulated gate electrode. The semiconductor body has a contact groove for the first electrode in an intermediate oxide layer. Highly doped zones of a first conduction type are located in edge regions of the source connection zone. Below the highly doped zones of the first conduction type, there are highly doped zones of a body zone with a complementary conduction type. In a central region of the source connection zone, the body zone has a net charge carrier concentration with a complementary conduction type which is lower than the charge carrier concentration in the edge regions of the source connection zone.

    摘要: According to one embodiment, a semiconductor device comprises a body of a first conductivity type having a source region and a channel, the body being in contact with a top contact layer. The device also comprises a gate arranged adjacent the channel and a drift zone of a second conductivity type arranged between the body and a bottom contact layer. An integrated diode is formed partially by a first zone of the first conductivity type within the body and being in contact with the top contact layer and a second zone of the second conductivity type being in contact with the bottom contact layer. A reduced charge carrier concentration region is formed in the drift zone having a continuously increasing charge carrier lifetime in the vertical direction so that the charge carrier lifetime is lowest near the body and highest near the bottom contact layer.

    摘要: A semiconductor device in one embodiment has a first connection region, a second connection region and a semiconductor volume arranged between the first and second connection regions. Provision is made, within the semiconductor volume, in the vicinity of the second connection region, of a field stop zone for spatially delimiting a space charge zone that can be formed in the semiconductor volume, and of an anode region adjoining the first connection region. The dopant concentration profile within the semiconductor volume is configured such that the integral of the ionized dopant charge over the semiconductor volume, proceeding from an interface of the anode region which faces the second connection region, in the direction of the second connection region, reaches a quantity of charge corresponding to the breakdown charge of the semiconductor device only near the interface of the field stop zone which faces the second connection region.
