  • Method of forming a solder interconnection capable of sustained high power levels between a semiconductor device and a supporting substrate
    Patent number: 4360142
    Abstract: A process for forming ball limiting metallurgy pad structure for a semiconductor device solder bond interconnection comprising:forming a conductive layer that is adherent to the semiconductor device passivating layer,forming a relatively thick layer of a material having a high thermal conductivity,forming a barrier layer that protects the high conductivity layer by physically preventing any interaction or alloying with the subsequent layers, andforming a layer of a material that is solder wettable.
    Type: Grant
    Filed: May 8, 1981
    Date of Patent: November 23, 1982
    Assignee: International Business Machines Corporation
    Inventors: Charles Carpenter, Joseph F. Fugardi, Lawrence V. Gregor, Peter S. Grosewald, Morton D. Reeber
