  • Method of making a ceramic semiconductor package having crack arrestor patterns
    Patent number: 4976814
    Abstract: A ceramic semiconductor package wherein metal crack arrestor patterns are formed in the corners of the package thereby increasing the strength of the package and acting as a barrier to microcracks. The metal crack arrestor patterns may be electrically and physically isolated from metal interconnect lines in the package and also may be formed using the same processing steps that are used to form the metal interconnect lines.
    Type: Grant
    Filed: December 18, 1989
    Date of Patent: December 11, 1990
    Assignee: Motorola, Inc.
    Inventors: Kent M. Blumenshine, Harris L. Marcus, Kathleen A. Long-Daugherty
