Abstract
Electromigration behavior in the Sn96.5Ag3.0Cu0.5 solder lines was investigated and compared Sn96.5Ag3.0Cu0.5 with eutectic SnPb. Measurements were made for relevant parameters for electromigration of the solder, such as drift velocity, threshold current density, activation energy, as well as the product of diffusivity and effective charge number (DZ
선형구조의 시편을 사용하여 Sn96.5Ag3.0Cu0.5의 electromigration 특성을 살펴보고 공정 조성의 SnPb의 electromigration특성과 비교, 분석하였다. SnAgCu의 electromigration에 관한 특성 중 시간에 따른 물질의 이동 양상과 여러 가지 electromigration 매개변수 (활성화 에너지, 임계 전류밀도, 확산계수와 유효전하수의 곱)을 살펴보았다. 임계 전류 밀도는
