Abstract:
1. A vertical semiconductor component, comprising: a semiconductor body of a first conductivity type and having a surface region with a surface; at least one zone of a second conductivity type, opposite said first conductivity type, embedded in said surface region of said semiconductor body; and regions of said second conductivity type disposed in said semiconductor body in a plane running substantially parallel to said surface of said surface region, said regions sufficiently highly doped that they cannot be depleted of charge carriers when a voltage is applied in a reverse direction and in a forward direction of a pn junction formed by said semiconductor body and said zone of said second conductivity type; said zone having a lower edge and said regions being floating and having upper edges, a vertical distance between said zone and said regions being chosen such that a vertical line integral between said lower edge of said zone and said upper edges of said regions facing said zone, across a doping of said semiconductor body remains below a specific breakdown charge, which is dependent on a material forming said semiconductor body.
