近年来由于红外系统应用的发展,推动了多元红外探测器的研究和使用。在红外多目标搜索和跟踪、红外成像、红外制导、控制卫星飞行姿态等系统中都已采用多元红外探测器。在红外系统中采用的探测器少则几元多则几百元,构成复杂的图案,要求面积精度高、一致性好,这在制备工艺上比单元器件要复杂得多。多元器件在工艺上比较关键的是电极的焊接和引出问题。因它不能像单元那样用铟球焊。一般采用在光敏面上蒸发铟,然后用热
In recent years due to the development of the application of infrared system, it has promoted the research and use of multivariate infrared detectors. In infrared multi-target search and tracking, infrared imaging, infrared guidance, control satellite flight attitude and other systems have been using multiple infrared detectors. Detectors used in the infrared system, ranging from a few dollars more than a few hundred dollars, constitute a complex pattern, requiring high precision area, consistency, which is much more complex than the single device in the preparation process. Multiple components in the process is more critical is the electrode welding and lead to the problem. It can not be welded with indium balls like cells. Generally used in the light-sensitive surface evaporated indium, and then with heat
