    • One embodiment of the present invention provides a method for fabricating a highly reflective electrode in a light-emitting device. During the fabrication process, a multilayer semiconductor structure is fabricated on a growth substrate, wherein the multilayer semiconductor structure includes a first doped semiconductor layer, a second doped semiconductor layer, and/or a multi-quantum-wells (MQW) active layer. The method further includes the followings operations: forming a contact-assist metal layer on the first doped semiconductor layer, annealing the multilayer structure to activate the first doped semiconductor layer, removing the contact-assist metal layer, forming a reflective ohmic-contact metal layer on the first doped semiconductor layer, forming a bonding layer coupled to the reflective ohmic-contact metal layer, bonding the multilayer structure to a conductive substrate, removing the growth substrate, forming a first electrode coupled to the conductive substrate, and forming a second electrode on the second doped semiconductor layer.

    • A portable cooling device has a vacuum bottle, a pump, an outflow pipe, a thermal exchanger and a return pipe. The vacuum bottle holds a coolant and has an outer casing and a vacuum flask. The outer casing has a chamber. The vacuum flask is mounted in the chamber. The pump is mounted on the vacuum bottle to pump the coolant out of the vacuum bottle. The outflow pipe connects to the pump. The thermal exchanger connects to the outflow pipe, is filled by the coolant and is placed adjacent to a person to lower his body temperature. The return pipe connects between the thermal exchanger and the vacuum bottle to form a flow circle. Consequently, the portable cooling device efficiently cools the body temperature. Moreover, having the vacuum bottle to hold and insulate the coolant elongates effective cooling time of the cooling device.
    • 便携式冷却装置具有真空瓶,泵,流出管,热交换器和回流管。 真空瓶保持冷却液并具有外壳和真空瓶。 外壳具有一个室。 将真空瓶安装在室中。 泵安装在真空瓶上,以将冷却剂从真空瓶中抽出。 流出管连接到泵。 热交换器连接到流出管,由冷却剂填充并且被放置在与人相邻以降低其体温。 回流管连接在热交换器和真空瓶之间以形成流动圆。 因此,便携式冷却装置有效地冷却体温。 此外,使真空瓶保持并使冷却剂绝缘物延长冷却装置的有效冷却时间。
