摘要：
Direct Transfer Bonding (DTB) is considered a competitive candidate to achieve a Die-to-Wafer Direct/Hybrid Bonding (DB/HB). In this study, we proposed and demonstrated the feasibility of a mechanism for image recognition and alignment over a chip carrier tape to achieve high joint accuracy, which has not been achieved with conventional DTB approach. It was confirmed that <100 nm level alignment can be achieved with this method. The DTB with this method will realize a low-cost and versatile Die-to-Wafer DB/HB.
