Patents by Inventor Man Chung Raymond Ng

Man Chung Raymond Ng 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: 7648901
    Abstract: A manufacturing process and apparatus therefore are provided for processing an electronic device comprising oxidizable material during processing. The electronic device is located inside a chamber and is heated a processing temperature with a heater. A reductive atmosphere is created in the chamber by supplying a gas comprising glycolic acid vapor while processing the electronic device at the processing temperature.
    Type: Grant
    Filed: September 28, 2006
    Date of Patent: January 19, 2010
    Assignee: ASM Assembly Automation Ltd.

  • Patent number: 7179346
    Abstract: An apparatus is provided for transferring components from a pick-up position amongst a supply of components to a placement position on a receptor, such as a die pad, during semiconductor processing. It includes a first delivery device and a second delivery device operative to alternatively transfer the components from the pick-up position to the placement position. The second delivery device is arranged opposite the first delivery device about a line passing through the pick-up position and the placement position.

  • Patent number: 7084532
    Abstract: The invention provides an apparatus and a method for positioning an object coupled to a first support structure and a second support structure. A first actuator drives the first support structure along a first axis and a second actuator drives the first support structure along a second axis orthogonal to the first axis. A third actuator comprising a forcer and a stator is provided for driving the second support structure that is guided for movement relative to the first support structure along a third axis orthogonal to the first and second axes. The forcer is coupled to the second support structure and is movable with respect to the stator, and the stator is relatively stationary and decoupled from the second support structure.

  • Patent number: 6991967
    Abstract: The invention provides an apparatus for die attachment onto a substrate including non-metallic material, and metallic material that is adapted to receive a die having a eutectic coating. A heating conduit is provided through which the substrate is movable for heating the metallic material to a eutectic bonding temperature to facilitate bonding between the die and the metallic material at a die-attach position. An induction heating device at the die-attach position heats the metallic material of the substrate to the eutectic bonding temperature prior to attaching a die onto the metallic material.
