  • Publication number: 20130341764
    Abstract: In a method for manufacturing a diode, a semiconductor crystal wafer is used to produce a p-n or n-p junction, which extends in planar fashion across the top side of a semiconductor crystal wafer. Separation edges form perpendicularly to the top side of the semiconductor crystal wafer, which edges extend across the p-n or n-p junction. The separation of the semiconductor crystal wafer is achieved in that, starting from a disturbance, a fissure is propagated by local heating and local cooling of the semiconductor crystal wafer. The separation fissure thus formed extends along crystal planes of the semiconductor crystal, which avoids the formation of defects in the area of the p-n or n-p junction.

  • Patent number: 8604592
    Abstract: The present invention provides a technique for improving the reliability of a semiconductor device where spreading of cracking that occurs at the time of dicing to a seal ring can be restricted even in a semiconductor device with a low-k film used as an interlayer insulating film. Dummy vias are formed in each layer on a dicing region side. The dummy vias are formed at the same intervals in a matrix as viewed in a top view. Even in the case where cracking occurs at the time of dicing, the cracking can be prevented from spreading to a seal ring by the dummy vias. As a result, resistance to moisture absorbed in a circuit formation region can be improved, and deterioration in reliability can be prevented.
