Abstract
Description
즉, 접합 SOI 웨이퍼를 제조하기 위해서는 두 장의 도너 및 핸들 웨이퍼(10,20)의 표면에 입자(particle) 등의 오염물질이 없는 상태로 세정하고, 표면을 활성화하여 접합시킨다.
이때 상기 세정은 통상의 습식 세정방법이 이용되며, 이러한 습식 세정 후 건조 공정을 실시하면 도너 및 핸들 웨이퍼(10,20)의 표면이 활성화가 되는데, 상기한 건조는 통상의 건조 방법인 스핀건조기(Spin Dryer)를 사용한다.
상기와 같은 습식 세정 방법과 건조 방법은 공지기술로 한국 공개특허공보 제2000-0038562호(2000. 07. 05)와, 한국 공개특허공보 제2003-0008163호(2003. 01. 24) 등에 기재되어 있다.
