    摘要: In a semiconductor die, source zones of a first conductivity type and body zones of a second conductivity type are formed. Both the source and the body zones adjoin a first surface of the semiconductor die in first sections. An impurity source is provided in contact with the first sections of the first surface. The impurity source is tempered so that atoms of a metallic recombination element diffuse out from the impurity source into the semiconductor die. Then impurities of the second conductivity type are introduced into the semiconductor die to form body contact zones between two neighboring source zones, respectively. The atoms of the metallic recombination element reduce the reverse recovery charge in the semiconductor die. Providing the body contact zones after tempering the platinum source provides uniform and reliable body contacts.

    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.
