Abstract: A bond pad with micro-protrusions for direct metallic bonding. In one embodiment, a semiconductor device comprises a semiconductor substrate, a through-silicon via (TSV) extending through the semiconductor substrate, and a copper pad electrically connected to the TSV and having a coupling side. The semiconductor device further includes a copper element that projects away from the coupling side of the copper pad. In another embodiment, a bonded semiconductor assembly comprises a first semiconductor substrate with a first TSV and a first copper pad electrically coupled to the first TSV, wherein the first copper pad has a first coupling side. The bonded semiconductor assembly further comprises a second semiconductor substrate, opposite to the first semiconductor substrate, the second semiconductor substrate comprising a second copper pad having a second coupling side. A plurality of copper connecting elements extend between the first and second coupling sides of the first and second copper pads.

Abstract: A microelectronic component package includes a plurality of electrical leads which are coupled to a microelectronic component and which have exposed lengths extending outwardly beyond a peripheral edge of an encapsulant. A plurality of terminals may be positioned proximate a terminal face of the encapsulant and these terminals may be electrically coupled to the same leads. This can facilitate connection of the microelectronic component to a substrate using the leads as a conventional leaded package. The terminals, however, can facilitate stacking of the leaded package with one or more additional microelectronic components, e.g., a BGA package.
