Abstract:
본 발명은 와이어 코팅 물질이 본딩 와이어와 반도체 칩 및 기판의 접합 부분을 덮도록 주입되는 칩 적층형 패키지에 관한 것이다. 반도체 칩의 소형화와 적층되는 반도체 칩 수의 증가로 인하여, 칩 적층형 패키지의 와이어 길이가 증가하고 있다. 긴 와이어는 몰딩 공정시 와이어 쳐짐 및 스위핑 등의 문제를 야기하므로 디스펜싱 공정을 하지만, 이는 열적 변화에 의한 와이어 볼 들뜸 문제를 극복하지 못한다. 본 발명은 와이어와 반도체 칩 및 기판의 접합 부분을 덮도록 와이어 코팅 물질을 주입한다. 이로 인해, 와이어 볼 들뜸 현상이 방지되어 신뢰성이 향상되고, 고집적화 및 소형화 추세에 부응하는 패키지를 구현할 수 있다. 본딩 와이어, 와이어 코팅 물질, 와이어 볼, 와이어 볼 들뜸, 칩 적층형 패키지
