Abstract:
1. A power semiconductor component comprising: a semiconductor base body including a first surface and a first doping region having a first doping of a first type of doping, said first surface having first and second partial areas; a contact region having a second doping of a second type of doping different from said first doping, and also having a first doping profile, said contact region being formed in said base body and forming a pn junction with said first region of said base body; and at least two field rings, each having a second doping of said second type of doping with a second doping profile different from said first doping profile, said second doping profile defining a contour of said second doping profile; and a trench-type cutout associated with each said field ring, each said trench-type cutout having a surface that follows said contour of its respective second doping profile; wherein said contact region and said field rings are arranged at respective ones of said first and second partial areas of said base body and extend into said base body.
