    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.

    摘要: A semiconductor device includes a first trench and a second trench extending into a semiconductor body from a surface. A body region of a first conductivity type adjoins a first sidewall of the first trench and a first sidewall of the second trench, the body region including a channel portion adjoining to a source structure and being configured to be controlled in its conductivity by a gate structure. The channel portion is formed at the first sidewall of the second trench and is not formed at the first sidewall of the first trench. An electrically floating semiconductor zone of the first conductivity type adjoins the first trench and has a bottom side located deeper within the semiconductor body than the bottom side of the body region.

    摘要: A semiconductor element includes a semiconductor layer having a first doping density, a metallization, and a contact area located between the semiconductor layer and the metallization. The contact area includes at least one first semiconductor area that has a second doping density higher than the first doping density, and at least one second semiconductor area in the semiconductor layer. The second semiconductor area is in contact with the metallization and provides lower ohmic resistance to the metallization than a direct contact between the semiconductor layer and the metallization provides or would provide.
