ABSTRACT:
A method of producing an electrical contact, with a low contact resistance, on a semiconductor bodies, particularly for luminescence diodes of semiconductor material, and which is also suitable for securing such a semiconductor body on an electrically conductive body acting as a heat sink, in which small metal contacts arranged in the form of a raster pattern are alloyed at an increased temperature, on the surface of the semiconductor body to be contacted, with the sum of the surface areas of all the metal contacts being small in relation to the surface area of the semiconductor body, and thereafter securing the surface of the semiconductor body, provided with such metal contacts, to a metal heat sink by an electrically and thermally conductive adhesive layer.
