    摘要: A main thyristor (1) has a recovery protection which is integrated into a drive thyristor (2) whose n-doped emitter (25) is electrically connected to a main thyristor control terminal (140). Moreover, the p-doped emitter (28) of the drive thyristor (2) is electrically connected to the p-doped emitter (18) of the main thyristor (1). Various optional measures for realizing a recovery protection are provided in this case. A method for producing a thyristor system having a main thyristor and a drive thyristor, the drive thyristor (2) having anode short circuits (211) involves introducing particles (230) into a target region (225) of the semiconductor body (200) of the drive thyristor (2), the distance between the target region (225) and a front side (201) of the semiconductor body (200) opposite to the rear side (202) being less than or equal to the distance between the p-doped emitter (28) and the front side (201).

    摘要: A thyristor includes a semiconductor body having an anode-side base zone of a first conductance type, and having a cathode-side base zone of the second, opposite conductance type, and has cathode-side and anode-side emitter zones. An anode-side defect zone is included within the anode-side base zone, in which the free charge carriers have a reduced life, with a predetermined thickness of at least 20 &mgr;m. The defect zone may be produced by anode-side irradiation of predetermined regions of the semiconductor body with charged particles, and with heat treatment of the semiconductor body in order to stabilize the defect zone.

    摘要: A vertical semiconductor device includes a semiconductor body, and first and second contacts on opposite sides of the semiconductor body. A plurality of regions are formed in the semiconductor body including, in a direction from the first contact to the second contact, a first region of a first conductivity type, a second region of a second conductivity type; and a third region of the first conductivity type. The third region is electrically connected to the second contact. A semiconductor zone of the second conductivity type and increased doping density is arranged in the second region. The semiconductor zone separates a first part of the second region from a second part of the second region. The semiconductor zone has a maximum doping density exceeding about 1016 cm−3 and a thickness along the direction from the first contact to the second contact of less than about 3 μm.

    摘要: A semiconductor component has a first and a second contact-making region, and a semiconductor volume arranged between the first and the second contact-making region. Within the semiconductor volume, it is possible to generate a current flow that runs from the first contact-making region to the second contact-making region, or vice versa. The semiconductor volume and/or the contact-making regions are configured in such a way that the local flow cross-section of a locally elevated current flow, which is caused by current splitting, is enlarged at least in partial regions of the semiconductor volume.
