Abstract:
1. A method of producing an electrical or electronic component wherein [A] at least one overhanging and/or protruding contact is formed and/or thickened on the front face of a wafer of semiconductive or insulating material in plate or disk form, [B.1] the rear face of the wafer is applied to a stretchable or extensible film, [B.2] the wafer is divided into individual discrete or integrated devices [B.3] the film is stretched or extended, [C.1.a] the front faces of the devices are coated with at least one front-face encapsulant [C.1.b] at least one side-face encapsulant is loaded, preferably from the area adjacent the front faces of the devices, into the gaps which are formed between the individual devices when the film is stretched or extended, [C.1.a] the rear faces of the devices are coated with at least one rear-face encapsulant [C.2.b] the side-face encapsulant is loaded from the area adjacent the rear faces of the devices into the gaps which are formed between the individual devices when the film is stretched or extended, [D.1] at least one overhanging and/or protruding and in particular ball-shaped or spherical electrode is applied to each of the contacts, and [E] the devices are so separated to form the individual components that the side faces of the individual components that are created by the division remain coated with the side-face encapsulant that was loaded into the gaps, characterized in that both the side-face encapsulant and the rear-face encapsulant are formed at least partly and/or at least of layers, but with a connection between the parts or layers, of electrically conducting or electrically conductive material.
