Abstract:
1. A microelectronic assembly, comprising: a semiconductor chip having a first face, a second face, and a plurality of chip contacts exposed at the first face; a substrate juxtaposed with one of the first or second faces, the substrate having a plurality of substrate contacts exposed at a face of the substrate; and a first electrically conductive bond wire and a second electrically conductive bond wire, the first and second bond wires electrically connecting a first chip contact of the plurality of chip contacts with a corresponding first substrate contact of the plurality of substrate contacts and providing parallel conductive paths between the first chip contact and first substrate contact, the first bond wire having a first end metallurgically joined to the first chip contact and a second end metallurgically joined to the first substrate contact, wherein one of the first and second ends of the first bond wire includes a ball, and one of the first and second ends of the second bond wire includes a ball, the ball of the second bond wire being metallurgically joined directly to one of the first and second ends of the first bond wire, an end of the second bond wire remote from the ball of the second bond wire is metallurgically joined to the ball of the first bond wire, and wherein the second bond wire does not touch either the first chip contact or the first substrate contact.
