以下、本発明の第2の実施の形態について説明する。図4および図5は、第2の実施の形態にかかる半導体装置の製造方法を示す模式図である。なお、第1の実施の形態と重複する説明は省略する。まず、図4(a)に、第2の実施の形態にかかる半導体装置の製造方法により作製された半導体装置の構成を示す。
以下、本発明の第3の実施の形態について説明する。図6は、第1の実施の形態において説明した方法で基板Wの面内方向での平面形状が略矩形の再配置配線層を作製したロジックチップ31およびメモリチップ(例えばDRAM)32をフリップチップ接続した状態を示す模式図である。図6(a)は、ここでは、ロジックチップ31を下側、メモリチップ32を上側に配置して接続する状態を示している。図6(b)は、ロジックチップ31を上面(再配置配線層6aが形成された側)から見た状態を示している。この場合、ロジックチップ31では、再配置配線層6a上全体に半田が広がっている。
以下、本発明の第4の実施の形態について説明する。図9は、第4の実施の形態にかかるロジックチップ31およびメモリチップ32をフリップチップ接続した状態を示す模式図である。図9では、ロジックチップ31を下側、メモリチップ32を上側に配置して接続する状態を示している。
