Abstract
A vertical semiconductor component. The component includes: a drift region having a first conductivity type; a trench structure on or above the drift region, a shielding structure situated laterally next to at least one sidewall of the trench structure on or above the drift region and having a second conductivity type, and the shielding structure having at least a part of a shielding structure-trench structure such that the shielding structure has at least a first region having a first thickness and a second region having a second thickness, and an edge termination structure on or above the drift region and having the second conductivity type, and the shielding structure having a first doping degree, and the edge termination structure having a second doping degree; and at least in the second region of the shielding structure, the edge termination structure being situated between the drift region and the shielding structure.
