Abstract:
1. A method for producing a plurality of semiconductor chips for semiconductor components with cell structures, comprising: patterning a semiconductor wafer composed of a monocrystalline semiconductor body with cell structures for MOSFETs, IGBTs or JFETs with a lateral or vertical drift path arranged between a first region of the semiconductor body for a first cell electrode and a second region of the semiconductor body for a second cell electrode, wherein the first region has a surrounding body zone with semiconductor material doped complementarily to the drift path, which body zone can be activated by a cell control electrode in interaction with a component control electrode; arranging the cell structures in semiconductor chip positions to form a first active cell array provided below a first component electrode; arranging the cell structures in at least one partial region of the semiconductor chip positions to form a second active cell array of the partial region, the array being provided below the component control electrode; and providing a metallization on a first surface of the semiconductor body to form the first component electrode and the component contol electrode.
