Abstract:
1. A method for producing a plurality of electronic devices having external contact elements, which comprises the steps of: providing a metal plate having a plurality of device positions; forming cutouts in a top side of the metal plate at the device positions, a contour of the cutouts corresponding to a form of external sections of the external contact elements; applying a mask to the top side of the metal plate, the mask having openings formed therein in a region of the cutouts; depositing, via one of chemical deposition and electrodeposition, at least one core material in the cutouts and in the openings resulting in a formation of metallic bulges at edges of the openings in the mask; applying a metallic material to the metallic bulges; removing the mask; disposing semiconductor chips having contact areas at the device positions; electrically connecting the contact areas of the semiconductor chips to at least the metallic bulges; coating the metal plate with a plastic housing composition resulting in a composite body being produced; removing the metal plate; and separating the composite body into individual ones of the electronic devices.
