Abstract:
Methods, techniques, and structures relating to die packaging. In one exemplary implementation, a die package interconnect structure includes a semiconductor substrate and a first conducting layer in contact with the semiconductor substrate. The first conducting layer may include a base layer metal. The base layer metal may include Cu. The exemplary implementation may also include a diffusion barrier in contact with the first conducting layer and a wetting layer on top of the diffusion barrier. A bump layer may reside on top of the wetting layer, in which the bump layer may include Sn, and Sn may be electroplated. The diffusion barrier may be electroless and may be adapted to prevent Cu and Sn from diffusing through the diffusion barrier. Furthermore, the diffusion barrier may be further adapted to suppress a whisker-type formation in the bump layer.

Claim (Index 2):
An assembly comprising:\n a die; a pad disposed on the die, the pad including aluminum; a base layer metal on the pad, the base layer metal including titanium; a copper bump disposed on the base layer metal; a diffusion barrier layer on the copper bump, the diffusion barrier layer including nickel; and a solder layer on the diffusion barrier layer, the solder layer comprising tin, silver and copper.
