Abstract |
AB |
[EN] The invention relates to a method for producing a semiconductor component including semiconductor areas of different conductivity types which are alternately positioned in a semiconductor body. The semiconductor areas of different conductivity types extend at least from one first zone to a position near a second zone. Because of variable doping in trenches and in the trench fillings, an electric field is generated which increases from both the first zone and the second zone. |
