Abstract:
1. The contact bump construction for the formation of elevated contact sites on connecting surfaces of a substrate, particularly chip connecting surfaces, with a spacer body, whose at least partly electrically conductive surface is connected to the assigned connecting surface of the substrate through an electrical conductor, the spacer body ( 46 , 49 , 60 , 70 , 71 , 72 ) being constructed from a dielectric, and the conductor being formed at least partly as a surface conductor ( 43 , 65 ) arranged on the surface of the spacer body, characterized in that the spacer body ( 60 ) is arranged with a partial area ( 61 ) on a first partial surface ( 79 ) of the connecting surface ( 62 ) and also extends beyond the connecting surface, and the surface conductor ( 65 ) extends from a second partial area ( 80 ) of the connecting surface to an upper side ( 63 ) of the spacer body.
