    Abstract: Thermally induced stress in a semiconductor die, i.e., in a complex metallization system thereof, may be reduced by “dividing” a package substrate into two or more substrate sections, which may have formed therebetween an appropriate stress buffer region, for instance a region of superior resiliency. In this case, the total deformation of the package substrate may be reduced, thereby also reducing the thermally induced stress forces in the complex metallization system of the semiconductor die.

  • Publication number: 20110241182
    Abstract: An improved die seal ring is described which includes at least one break. In the region of the break in the die seal ring, the doping is modified so that the impedance of the electrical path across the break through the substrate is increased. Offsets in the break may also be used and the offset may be within a break in a track and/or between breaks in different tracks, where the die seal ring includes more than one track.

  • Patent number: 8026583
    Abstract: The invention relates to a flip-chip module with a semiconductor chip with contact posts, wherein the contact posts are connected electrically and mechanically to a substrate. Provided between the substrate and the semiconductor chip is a spacer, which is coupled mechanically to the substrate and/or the semiconductor chip. By this means, thermal stresses in the flip-chip module are absorbed by the spacer and kept away from the semiconductor chip. The invention also relates to a method for the production of a flip-chip module, in which firstly a spacer is located between the semiconductor chip and the substrate, after which the contact posts are soldered to the contact points of the substrate. Through the provision of the spacer the distance between the semiconductor chip and the substrate is set precisely, thereby improving the quality of the soldering points.

  • Patent number: 8004089
    Abstract: On the lower surface of a semiconductor construct having an external connection electrode, there are formed an insulating film having a planar size greater than that of the semiconductor construct, and a metal layer and a mask metal layer having a connection pad portion in which a first opening corresponding to the external connection electrode is formed. A laser beam is applied using the mask metal layer as a mask, and a second opening is thereby formed in a part of the insulating film corresponding to the external connection electrode. Then, a connection conductor is formed to connect a wiring line to the external connection electrode via the second opening of the insulating film.
