Abstract:
A method for contact-connecting a semiconductor component to a film provided with a metal layer, which comprises:selecting a solder material: containing at least two different substances selected from a group consisting of elementary metals and semiconductor materials, having a melting point at a temperature at which the film is not damaged, and being combinable with a metal to form one of an alloy and an intermetallic compound having a higher melting point than the film; disposing the solder material between a contact of the semiconductor component and the metal layer of the film; and subsequently causing the solder material to melt, combine with one of a metal of the contact of the semiconductor component and a metal of the metal layer of the film to form one of an alloy and an intermetallic compound having a higher melting point than the film, thereafter solidify, and produce a permanent electrically conducted connection of a material having a melting point higher than the melting point of the disposed solder material.
