Techniques for fabricating metal devices, such as vertical light-emitting diode (VLED) devices, power devices, laser diodes, and vertical cavity surface emitting laser devices, are provided. Devices produced accordingly may benefit from greater yields and enhanced performance over conventional metal devices, such as higher brightness of the light-emitting diode and increased thermal conductivity. Moreover, the invention discloses techniques in the fabrication arts that are applicable to GaN-based electronic devices in cases where there is a high heat dissipation rate of the metal devices that have an original non- (or low) thermally conductive and/or non- (or low) electrically conductive carrier substrate that has been removed.
摘要:
A charged capacitor switching device for a photoflash is provided and includes a flash control unit, a capacitor charging/discharging unit, a charged capacitor switching unit and an illumination modulator. The capacitor charging/discharging unit coupled to the flash control unit includes a plurality of capacitors connected in parallel and switches coupled thereto respectively. The charged capacitor switching unit determines whether each switch is opened or closed according to a compensation parameter. The illumination modulator compares an environmental illumination and a pre-flash illumination to generate a compared result, determines whether the compared result has reached a threshold, obtains the compensation parameter according to the compared result when the compared result is below the threshold, and drives the flash control unit to generate a flash illumination corresponding to the compensation parameter.
