重点研究了MCM-C基板中多层互连和厚膜电阻的可靠性.试验采用温度应力和电应力的双应力加速寿命试验.试验发现
温度小于180℃时互连失效在MCM-C基板失效中占主要地位
膜电阻失效相对互连失效可忽略不计.在温度高于180℃时膜电阻失效将起较大作用
即膜电阻比互连温度加速系数要大.重点计算了膜电阻和互连寿命分布及加速系数.
The paper mainly studies the reliability of multi-layer intercnonections
vias and thick-film resistors in Multi-chip Module-Ceramic(MCM-C) substrates.Temperature stress and voltage stress are used to accelerate the life test.The results show that when the temperature is under 180℃
the failure of metal lines plays a much more important role than the failure of film resistors;but when it's over 180℃
the failure of film resistors will also be important.The paper also calculated the lifetime and accelerating coefficient of metal lines and thick-film resistors.
