  • Publication number: 20100041216
    Abstract: The present invention relates to a method of forming a nitride semiconductor substrate. This method includes steps of providing a substrate and then forming an epitaxy layer on the substrate. A patterned mask layer is formed on the epitaxy layer, wherein the patterned mask layer exposes a portion of the epitaxy layer. Next, an oxidation process is performed to oxidize the exposed epitaxy layer so as to form a plurality of dislocation blocking structures. The patterned mask layer is then removed. Further, a nitride semiconductor layer is formed on the epitaxy layer having the dislocation blocking structures.

  • Patent number: 7652463
    Abstract: A power converter for compensating a maximum output power includes a power switch, a control circuit, an oscillator and a frequency modulator. The control circuit generates a PWM signal in response to the pulse signal generated by the oscillator. The frequency modulator generates a second discharge signal to the oscillator for controlling the maximum output power of the power converter. The second discharge signal is decreased for prolonging a switching period of the PWM signal under a high-line voltage of the power converter.

  • Publication number: 20080288818
    Abstract: In an application system of a liquid crystal display, for protecting transmissions between a master terminal and a slave terminal, effects caused by an unstable power source of the slave terminal have to be reduced to a lowest degree. When the application system is reset or under normal operations with the power source having a suddenly-decreased or suddenly-unstable voltage level, the transmission between the master terminal and the slave terminal have to be terminated, and related data of the terminated transmission is temporarily stored. When the voltage of the slave terminal is confirmed to reach to a stable voltage over a predetermined duration, the transmission may be restored by the stored data.
