Abstract
【解決手段】 本発明の半導体装置の製造方法は、マザーチップの回路面に半田ボールを形成する第1工程と、第1工程の後に、マザーチップの回路面にドータチップをフリップチップ接続する第2工程と、半田ボールを用いて回路基板上にマザーチップをフリップチップ接続する第3工程とを有する。
【選択図】 図1
Description
図1は、本発明の実施の形態1に係る半導体装置の製造方法を示すフローチャートである。このフローチャート及び図2〜4を参照しながら、実施の形態1に係る半導体装置の製造方法について説明する。
実施の形態2に係る半導体装置の製造方法は、マザーチップ10の回路面に半田ペーストを堆積する工程が実施の形態1の図2(e)とは異なる。その他の工程は、実施の形態1と同様である。
実施の形態3に係る半導体装置の製造方法は、マザーチップ10の回路面にドータチップ20をフリップチップ接続する工程が実施の形態1の図4(a)とは異なる。その他の工程は、実施の形態1と同様である。
図7は、本発明の実施の形態4に係る半導体装置を示す断面図である。この半導体装置は、回路基板33の上面に、ドータチップ20に対応する領域に凹部35を設けたものである。その他の構成は実施の形態1と同様である。これにより、ドータチップ20が厚い場合でも、マザーチップ10と回路基板33を良好にフリップチップ接続することができる。
図8は、本発明の実施の形態5に係る半導体装置を示す断面図である。この半導体装置は、本発明をマザーチップ10の回路面に再配線層40を形成し、その上を表面保護膜41で覆っている。ただし、ドータチップ20を接続する領域には再配線層40及び表面保護膜41は形成しないようにする。これにより、メタルポスト16,26の高さを確保することができるため、アンダーフィルの際にチップ間に樹脂34を注入しやすくなる。
図9は、本発明の実施の形態6に係る半導体装置を示す断面図である。この半導体装置は、マザーチップ10の回路面に、ドータチップ20の他に、チップコンデンサ42が搭載されている。その他の構成は実施の形態1と同様である。
