    摘要: A semiconductor device includes a first contact in low Ohmic contact with a source region of the device and a first portion of a body region of the device formed in an active area of the device, and a second contact in low Ohmic contact with a second portion of the body region formed in a peripheral area of the device. The minimum width of the second contact at a first surface of the device is larger than the minimum width of the first contact at the first surface so that maximum current density during commutating the semiconductor device is reduced and thus the risk of device damage during hard commutating is also reduced.

    摘要: A semiconductor device with a dynamic gate drain capacitance. One embodiment provides a semiconductor device. The device includes a semiconductor substrate, a field effect transistor structure including a source region, a first body region, a drain region, a gate electrode structure and a gate insulating layer. The gate insulating layer is arranged between the gate electrode structure and the body region. The gate electrode structure and the drain region partially form a capacitor structure including a gate-drain capacitance configured to dynamically change with varying reverse voltages applied between the source and drain regions. The gate-drain capacitance includes at least one local maximum at a given threshold or a plateau-like course at given reverse voltage.

    摘要: A semiconductor device includes a first emitter region of a first conductivity type, a second emitter region of a second conductivity type complementary to the first conductivity type, and a drift region of the second conductivity type arranged in a semiconductor body. The first and second emitter regions are arranged between the drift region and a first electrode and are each connected to the first electrode. A device cell of a cell region includes a body region of the first conductivity type adjoining the drift region, a source region of the second conductivity type adjoining the body region, and a gate electrode adjacent the body region and dielectrically insulated from the body region by a gate dielectric. A second electrode is electrically connected to the source region and the body region. A floating parasitic region of the first conductivity type is disposed outside the cell region.
