  • Method for the production of highly pure copper thin films by chemical vapor deposition
    Patent number: 5441766
    Abstract: The present invention relates to a method for the production of highly pure copper thin films free from carbonaceous impurities, which comprises depositing a thin copper film using an organic copper compound precursor containing ketoesters alone or in combination with a Lewis base as ligands, by which the ligands are not thermally decomposed during the vapor deposition.

  • Internal routing method for load balancing
    Patent number: 5271003
    Abstract: An internal routing method in an internal network for improving signaling message processing capability by balancing the workload among message handling processors (MHP) in common channel signaling system used in electronic exchanges. An internal routing algorithm is provided in the internal network to balance the workload among MHP's based on the characteristics of a circuit identification code (CIC). An identifying trunk circuit is uniformly distributed, and a load unbalancing factor is formulated approximately as a function of the number of failed MHP's as a worst case. With this approach, all MHP's are loaded almost equally regardless of the number of failed MHP's.
