  • Method for fabricating highly conductive vias
    Patent number: 5619791
    Abstract: The thickness uniformity of a plated metal layer inside a via hole can be enhanced by intersecting a conductive via with an insulating aperture before plating. The new via configuration improves the mass transfer of the plating. It is believed that the apertures lower the local solution ohmic resistance near the via holes. The method can be applied to the manufacture of a wide variety of circuit boards.

  • Optical fiber amplifier and a glass therefor
    Patent number: 5378664
    Abstract: A chalcogenide glass that is doped with praseodymium and contains a rare earth metal is disclosed. The rare earth metal is at least 10 mole percent of the metals in the glass. The concentration of the praseodymium in the glass is at least 200 ppm. The chalcogenide glass, when formed into an amplifier for an optical fiber transmission system, efficiently amplifies optical signals in the signal band of 1.3 .mu.m.
