    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 component includes a sequence of layers, the sequence of layers including a first insulator layer, a first semiconductor layer disposed on the first insulator layer, a second insulator layer disposed on the first semiconductor layer, and a second semiconductor layer disposed on the second insulator layer. The semiconductor component also includes a plurality of devices at least partly formed in the first semiconductor layer. A first one of the plurality of devices is a power transistor formed in a first region of the first semiconductor layer and a first region of the second semiconductor layer. The first region of the first and second semiconductor layers are in electrical contact with one another through a first opening in the second insulator layer.
