  • Amorphous Si/Au eutectic wafer bonding structure
    Patent number: 7507636
    Abstract: An amorphous Si (silicon)/Au (gold) eutectic wafer bonding structure is fabricated. An amorphous Si obtained through coating or growth contacts with Au for bonding. The bonding layer is a Si/Au eutectic layer. Si is prevented from being precipitated. The bonding structure has a fast reaction ratio and a uniformed reaction. Thus, an electrical device has an improved electricity and reliability.
    Type: Grant
    Filed: January 5, 2007
    Date of Patent: March 24, 2009
    Assignee: National Central University
    Inventors: Cheng-yi Liu, Po-Han Chan, Ching-Liang Lin

  • Method of fabricating GaN device with laser
    Publication number: 20080113463
    Abstract: A laser is used in fabricating a thin film gallium nitride (GaN) light emitting diode (LED). The laser has a wave length to be absorbed by GaN. The laser is used to define a GaN grain. And the laser is used to lift off a substrate after obtaining a bonding layer of GaN. Fabrication procedure is thus simplified.

  • Radiator including a heat sink and a fan
    Patent number: 7117932
    Abstract: A radiator includes a heat sink (10), a fan holder (50) and a fan (30). The heat sink includes a heat-absorbing member (12, 18) that defines a cavity (20) in an end thereof. The fan holder includes a central hub (52) secured into the cavity of the heat sink. The fan is positioned to the heat sink via the fan holder.
