  • Patent number: 7645624
    Abstract: A method for self bonding epitaxy includes forming a passivation layer on a substrate surface of a semiconductor lighting element; etching to form recesses and protrusive portions with the passivation layer located thereon; starting forming epitaxy on the bottom surface of the recesses; filling the recesses with an Epi layer; then covering the protrusive portions and starting self bonding upwards the epitaxy to finish the Epi layer structure. Such a self bonding epitaxy growing technique can prevent cavity generation caused by parameter errors of the epitaxy and reduce defect density, and improve the quality of the Epi layer and increase internal quantum efficiency.

  • Publication number: 20090091950
    Abstract: A power converting circuit with an open load protection function is electrically connected to a power supply providing a first voltage level, and outputs a second voltage level to drive a load. The power converting circuit includes a DC/DC converter and a rectifying element disposed between an output node and an input node of the DC/DC converter that forms a discharging loop with the DC/DC converter. The DC/DC converter receives the power, converts the first voltage level into the second voltage level and outputs the second voltage level to the load. The rectifying element is utilized to release a surge voltage produced by the DC/DC converter in an open load condition.
