Abstract

Purpose Product reliability investigations typically include accelerated humidity testing. Originally, the "standard" test was a biased 8501/85% Relative Humidity (RH) lifetest for 1000 hours. Recently, a substitute accelerated version of this test has been used. The accelerated version is called HAST (Highly Accelerated Stress Test). The HAST conditions are also biased, at 1300C, 85%°RH, and approximately 18 PSI overpressure. The duration of the HAST test is normally 96100 hours to be equivalent to the 85/85 testtY1 This study is intended to investigate thermal acceleration and show that equivalent HAST tests on Compound Semiconductors are more highly accelerated and could be conducted much faster.
湿度条件下化合物半导体的热加速度
产品可靠性调查通常包括加速湿度测试。最初,“标准”测试是偏差8501/85%相对湿度(RH)寿命测试1000小时。最近,该测试的替代加速版本已被使用。加速版本称为HAST(高度加速压力测试)。在1300C, 85% RH和大约18psi的超压下,HAST条件也有偏差。HAST测试的持续时间通常为96100小时,相当于85/85测试ty1本研究旨在研究热加速,并表明化合物半导体的等效HAST测试加速程度更高,可以更快地进行。
