Patent ID: 8541837

Claim:
A semiconductor device comprising: a source metallization; a first field-effect structure including a source region of a first conductivity type, the source region being electrically connected to the source metallization; a body region of a second conductivity type adjacent to the source region; a first gate electrode and a first insulating region arranged at least between the first gate electrode and the body region, the first gate electrode, the first insulating region and the body region forming a first capacitance, the first capacitance having a first capacitance per unit area; a second field-effect structure including a source region of the first conductivity type; a body region of the second conductivity type adjacent to the source region; an electrode structure and a second insulating region which is, in a first vertical cross-section, arranged at least between the electrode structure and the body region, the source region and the electrode structure being electrically connected to the source metallization; the electrode structure, the second insulating region and the body region forming a second capacitance, the second capacitance having a second capacitance per unit area; the second capacitance per unit area being larger than the first capacitance per unit area; and a body contact region of the second conductivity type which adjoins, in a second vertical cross-section, the electrode structure and the body region of at least one of the first field-effect structure and the second field-effect structure; wherein the body region to which the body contact region adjoins has a first doping concentration; and wherein the body contact region has a second doping concentration which is higher than the first doping concentration.
