Patents by Inventor Nelson Kuan

Nelson Kuan 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: 8344487
    Abstract: A packaged microchip has a lead frame with a die directly contacting at least a single, contiguous portion of the lead frame. The portion of the lead frame has a top surface forming a concavity and contacting the die. The packaged microchip also has mold material substantially encapsulating part of the top surface of the portion of the lead frame.
    Type: Grant
    Filed: June 28, 2007
    Date of Patent: January 1, 2013
    Assignee: Analog Devices, Inc.
    Inventors: Xin Zhang, Michael Judy, Kevin H. L. Chau, Nelson Kuan, Timothy Spooner, Chetan Paydenkar, Peter Farrell
  • Patent number: 7968807
    Abstract: A package apparatus has a base coupled with a lid to form a leadframe package. The package has first and second exterior surfaces with respective first and second contact patterns. The first and second contact patterns are substantially electrically identical to permit the package to be either vertically or horizontally mounted to an underlying apparatus.
    Type: Grant

  • Patent number: 6820988
    Abstract: This invention provides method and apparatus for fabricating a MEMS apparatus having a bulk element with hinges underneath. The bulk element may comprise single-crystal silicon, fabricated by way of bulk micromachining techniques. The hinges may be made of thin-films, fabricated by way of surface micromachining techniques. A distinct feature of the MEMS apparatus of the present invention is that by disposing the hinges underneath the bulk element, the surface of the bulk element can be maximized and the entire surface becomes usable (e.g., for optical beam manipulation). Such a feature would be highly advantageous in making arrayed MEMS devices, such as an array of MEMS mirrors with a high optical fill factor. Further, by advantageously making use of both bulk and surface micromachining techniques, a MEMS mirror thus produced is equipped with a large and flat mirror along with flexible hinges, hence capable of achieving a substantial rotational range at modest electrostatic drive voltages.
