    • The present invention is directed to a method for testing the leakage rate of an encapsulated device comprising the step: bombing the device with a Neon and/or Argon atmosphere using a bombing pressure of at least more than environmental pressure and measuring the quality factor before and after bombing. Preferably, the bombing time is about 10 to 100 hours, and the bombing pressure is 1.5 to 100 bar, more preferably 1.5 to 5 bar and most preferably about 4 bar. With this test, the leakage rate of fine leaks of the device may be determined. This test is helpful in determining statistical surface contaminations or defects caused by wafer processing that affect the seal integrity just enough to cause shorter lifetimes. Further, dicing, die assembly and transfer molding may also introduce physical defects which may be detected with the present method. Finally, the inventive test method may be useful for process optimization: Hermeticity tests are a great help to optimize sealing processes.
    • 本发明涉及一种用于测试包封装置的泄漏率的方法,包括以下步骤:使用至少大于环境压力的轰炸压力,用氖气和/或氩气气氛轰炸该装置,并测量先前的质量因子, 轰炸后 优选地,轰炸时间为约10至100小时,轰炸压力为1.5至100巴,更优选为1.5至5巴,最优选为约4巴。 通过该测试,可以确定装置的微小泄漏的泄漏率。 该测试有助于确定影响密封完整性的晶片处理造成的统计表面污染或缺陷,足以导致更短的寿命。 此外,切割,模具组装和传递模塑也可能引入可用本方法检测的物理缺陷。 最后,本发明的测试方法可能对于工艺优化是有用的:密封性测试对于优化密封过程是非常有帮助的。
