  • Fluorinated carbon polymer composites
    Patent number: 5591285
    Abstract: Disclosed are structures comprising a composite of fluorinated particulate carbon dispersed in a polymer, the fluorinated carbon being present in an amount sufficient to reduce the dielectric constant of the composition, the structure also including electrical conductor patterns.The composite can be made conductive by irradiating it with an UV excimer laser.
    Type: Grant
    Filed: July 24, 1995
    Date of Patent: January 7, 1997
    Assignee: International Business Machines Corp.

  • Fluorinated carbon polymer composites
    Patent number: 5556899
    Abstract: Disclosed is a process of effecting a change in the dielectric constant and coefficient of thermal expansion of a polyimide material, by forming a composite based on a dispersion of 2-60 wt. % of fluorinated particulate carbon material and a polyimide or polyimide precursor, and heating the dispersion to about 400.degree. C. at 65.degree.-200.degree. C./second.
