    • Disclosed is a surface emitting laser device with a monolithically integrated monitor photodetector, which is combined with an automatic power control circuit, thereby being capable of more accurately controlling the surface emitting laser output power. A method is also disclosed, which is adapted to fabricate the surface emitting laser device. In accordance with, the present invention, the surface emitting laser device includes insulating layers each sandwiched between an intrinsic semiconductor layer and a doped semiconductor layer in a monitor photodetector adapted to partially absorb light emitted from a surface emitting laser, thereby outputting a detect signal for the light. The insulating layers serve to remove photocurrent resulting from spontaneous emission light emitted from the surface emitting laser. By this configuration, it is possible to accurately control the power of light emitted from the surface emitting laser through a laser window.

    • Provided are a reflow apparatus and method. The reflow apparatus includes a loader unit, a heating unit, an unloader unit, and a moving unit. The loader unit has an input module and an input stacker. Processing objects are stored in vertical stacks in magazines, and a plurality of magazines is stored in the input stacker. The magazines stored in the input stacker are moved to the input module and are introduced into the heating unit by the moving unit. Solder balls provided on the processing objects within the heating unit are quickly processed using an induction heating method. The processing objects that have undergone a reflow process are loaded in a magazine on an output module of the unloader unit and are then stored in an output stacker.
    • 提供回流装置和方法。 回流装置包括加载单元,加热单元,卸载单元和移动单元。 装载单元具有输入模块和输入堆垛机。 处理对象存储在杂志中的垂直堆栈中,并且多个杂志被存储在输入堆叠器中。 存储在输入堆叠器中的杂志被移动到输入模块,并通过移动单元被引入加热单元。 使用感应加热方法快速地处理设置在加热单元内的加工对象上的焊球。 已经经历回流处理的处理对象被装载在卸载单元的输出模块的仓库中,然后存储在输出堆垛机中。
