    Abstract: A bump contact electrically connects a conductor on a substrate and a contact pad on a semiconductor device mounted to the substrate. The first end of an electrically conductive pillar effects electrical contact and mechanical attachment of the pillar to the contact pad with the pillar projecting outwardly from the semiconductor device. A solder crown reflowable at a predetermined temperature into effecting electrical contact and mechanical attachment with the conductor is positioned in axial alignment with the second end of the pillar. A diffusion barrier electrically and mechanically joins the solder bump to the second end of the pillar and resists electro-migration into the first end of the solder crown of copper from the pillar. One diffusion barrier takes the form of a 2-20 micron thick control layer of nickel, palladium, titanium-tungsten, nickel-vanadium, or tantalum nitride positioned between the pillar and the solder crown.

  • Publication number: 20120299183
    Abstract: In a semiconductor device according to the present invention, a solder resist has a plurality of openings that expose electrodes. Solder bumps are formed in the openings and each have a solder ball portion protruding from the corresponding opening. The height of the openings is set to increase with increasing gap distance between the electrodes of an interposer substrate and board electrodes of a printed wiring board on which the semiconductor device is mounted. Thus, the solder bumps that correspond to sections where the gap distance is large can be increased in height, whereas the solder bumps that correspond to sections where the gap distance is small can be decreased in height, thereby avoiding the occurrence of defective joints caused by a reduction in size and thickness of the interposer substrate, as well as extending the lifespan of solder joints.
