<p>A method for producing a semiconductor device comprising a step a) of implanting an impurity dopant of a first conductivity type into said semiconductor layer (1) being doped according to a second opposite conductivity type for forming a first type doped surface layer (2) surrounded, except for the top surface thereof, by second conductivity type doped regions (3) of said semiconductor layer for forming a pn-junction (4) at the interface thereto. A highly doped additional semiconductor layer (5) is grown on top of said surface layer (2) for forming a contact layer allowing a low resistance ohmic contact to be established to the device so created.</p> |
