  • Patent number: 7371594
    Abstract: The present invention relates to a nitride semiconductor device and a method for fabricating the same. According to the present invention, there is an advantage in that trenches isolating respective nitride semiconductor unit devices from one another are filled with crack-inhibiting walls to remove voids, thereby minimizing cracks or damage that may occur in the nitride semiconductor unit devices during a laser lift-off process. In addition, there is an advantage in that the devices are bonded through a bonding-reinforcing plate or the crack-inhibiting walls to a carrier substrate with a bonding member coated thereon, thereby maintaining a strong bonding force to the carrier substrate.
