dc.description.abstract최근 반도체 패키지 구조는 점점 더 얇아지고 복잡해지고 있다. 두께가 얇아짐에 이종 계면에서 물성차이에 의한 박리는 심화될 수 있으며 따라서 계면의 신뢰성이 패키징 설계에 중요한 요소라 할 수 있다. 특히, 반도체 패키징에 많이 사용되는 폴리머는 온도와 수분에 영향을 크게 받기 때문에 환경에 따른 물성 변화 고려가 필수적이다. 따라서, 본 연구에서는 다양한 온도조건에서 수분의 흡습과 탈습을 모두 고려한 패키지 구조의 계면 박리 예측을 유한 요소 해석을 통해 수행하였다. 확산계수와 포화 수분 함량과 같은 재료의 물성은 흡습 실험을 통해 확보하였으며, 흡습 이후 TMA 와TGA 를 통하여 각 재료의 수분 팽창 계수를 확보하였다. 각 계면의 접합 강도 평가를 위해 수분의 영향을 고려하여 다양한 온도 조건에서 마이크로 전단 실험을 수행하였다. 이러한 물성을 바탕으로 온도와 수분에 의해 발생하는 변형을 모두 고려한 패키지 박리 예측 해석을 수행하였으며, 결과적으로 리플로우 공정 동안의 실시간 수분 탈습 거동을 고려한 계면 박리 예측을 성공적으로 수행하였다.;Recently, the semiconductor package structures are becoming thinner and more complex. As the thickness decrease, interfacial delamination due to material mismatch can be further maximized, so the reliability of interface is a critical issue in industry field. Especially, the polymers, which are widely used in semiconductor packaging, are significantly affected by the temperature and moisture. Therefore, in this study, the delamination prediction at the interface of package structure was performed through finite element analysis considering the moisture absorption and desorption under the various temperature conditions. The material properties such as diffusivity and saturated moisture content were obtained from moisture absorption test. The hygro-swelling coefficients of each material were analyzed through TMA and TGA after the moisture absorption. The micro-shear test was conducted to evaluate the adhesion strength of each interface at various temperatures considering the moisture effect. The finite element analysis of interfacial delamination was performed that considers both deformation due to temperature and moisture absorption. Consequently, the interfacial delamination was successfully predicted in consideration of the in-situ moisture desorption and temperature behavior during the reflow process.en_US
