Method for producing an electrode by means of a field effect controllable semiconductor component and field-effect-controllable semiconductor component

A field-effect-controllable semiconductor component, comprising:

• a semiconductor body having:
• a first zone of a first conduction type;
• a second zone of a second conduction type;
• and
• at least one trench extending into said semiconductor body in a vertical direction of the semiconductor body through the second zone;
• a control electrode disposed in said first trench;
• a first insulation layer disposed in said at least one trench and insulating said control electrode from said semiconductor body;
• a second insulation layer disposed in said at least one trench;
• and
• said control electrode having:
• a first electrode section adjacent said first insulation layer;
• a second electrode section;
• and
• an intermediate layer disposed between said first and second electrode sections;
• and;
• a field plate insulated from said semiconductor body by said second insulation layer, said field plate electrically conductively connected to said control electrode.
