Abstract
【解決手段】一面に形成された表面バンプFB及び積層方向から見て表面バンプFBと重なるように他面に形成された裏面バンプBBを含むコアチップCC1と、一面に形成された表面バンプFB及び積層方向から見て表面バンプFBと重ならないように他面に形成された裏面バンプBBを含むインターフェースチップIFとを準備し、コアチップCC1の裏面バンプBBとインターフェースチップIFの表面バンプFBが接続するように、インターフェースチップIFの裏面バンプBBに対応する位置に凹部GRを有するボンディングツールBTを用いて積層方向に重ね合わせる。これにより、積層時にチップに曲げモーメントが発生しないことからチップの破損を防止することが可能となる。
