  • Patent number: 8497206
    Abstract: A method of processing copper backside metal layer for semiconductor chips is disclosed. The backside of a semiconductor wafer, with electronic devices already fabricated on the front side, is first coated with a thin metal seed layer by either electroless plating or sputtering. Then, the copper backside metal layer is coated on the metal seed layer. The metal seed layer not only increases the adhesion between the front side metal layer and the copper backside metal layer through backside via holes, but also prevents metal peeling from semiconductor's substrate after subsequent fabrication processes, which is helpful for increasing the reliability of device performances. Suitable materials for the metal seed layer includes Pd, Au, Ni, Ag, Co, Cr, Pt, or their alloys, such as NiP, NiB, AuSn, Pt—Rh and the likes. The use of Pd as seed layer is particularly useful for the copper backside metal layer, because the Pd layer also acts as a diffusion barrier to prevent Cu atoms entering the semiconductor wafer.
