摘要:
A method of protecting through substrate via (TSV) die from bonding damage includes providing a substrate including a plurality of TSV die having a topside including active circuitry, a bottomside, and a plurality of TSVs that include an inner metal core that reaches from the topside to protruding TSV tips that extend out from the bottomside. A protective layer is formed on or applied to the bottomside of the TSV die including between and over the protruding TSV tips. The TSV die is bonded with its topside down onto a workpiece having a workpiece surface and its bottomside up and in contact with a bond head. The protective layer reduces damage from the bonding process including warpage of the TSV die by preventing the bond head from making direct contact to the protruding TSV tips.

At least one metal adhesion layer is formed on at least a Cu surface of a first device wafer. A second device wafer having another Cu surface is positioned atop the Cu surface of the first device wafer and on the at least one metal adhesion layer. The first and second device wafers are then bonded together. The bonding includes heating the devices wafers to a temperature of less than 400° C., with or without, application of an external applied pressure. During the heating, the two Cu surfaces are bonded together and the at least one metal adhesion layer gets oxygen atoms from the two Cu surfaces and forms at least one metal oxide bonding layer between the Cu surfaces.

A semiconductor device includes a substrate and a through via penetrating the substrate. The through via has a protruding portion at a first end thereof extending out from a first surface of the substrate and a second end of the via contacting an interconnection line proximate a second, opposite, end of the substrate. A wetting layer is positioned between the via and the substrate and extends over the protruding portion of the via. The wetting layer includes a material selected to improve an adhesive strength between the wetting layer and a solder ball contacting the wetting layer extending over the protruding portion of the via when a solder ball is coupled to the wetting layer.
