Patents by Inventor Donghang Liu

Donghang Liu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6832420
    Abstract: An electronic device has a plurality of capacitors in an ultra-small integrated package. The device has a plurality of terminal structures on one terminal side of the package to permit inverted mounting to a printed circuit board. The terminals are widely spaced, with the individual capacitors being located entirely in between. The device is produced on a suitable substrate using thin film manufacturing techniques. A lead-based dielectric having a high dielectric constant is preferably utilized for each capacitor to provide a relatively high-capacitance value in a relatively small plate area.
    Type: Grant

  • Patent number: 6285542
    Abstract: A very small electronic device adapted for inverted mounting to a circuit board includes a multiplicity of capacitors and resistors built on a substrate. The capacitors and resistors are interconnected so as to provide multiple RC circuits in various circuit arrangements. The multiple layers of the device are covered by an encapsulate having openings to expose terminal pads of the RC circuits. The openings are filled with solder to produce the individual terminations of the device in a ball grid array (BGA). The device saves cost and/or board space in the manufacture of larger electronic equipment through the elimination of multiple discrete components. In addition, very low inductance is achieved due to the close proximity of the device to a circuit board on which it is mounted.
