Abstract

A sucking electrode for shortening the turn-off time in a semiconductor component includes a diffusion zone of the sucking electrode, a zone adjoining the diffusion zone of the sucking electrode defining a junction therebetween, and a metal short-circuit disposed between the diffusion zone of the sucking electrode and the zone adjoining the diffusion zone of the sucking electrode. The diffusion zone of the sucking electrode is disposed inside the zone adjoining the diffusion zone of the sucking electrode. At least a portion of the junction between the diffusion zone of the sucking electrode and the zone adjoining the diffusion zone of the sucking electrode is free of metal plating.
