Description
図2〜図5は本発明の第1実施形態の電子部品実装構造の製造方法を示す断面図である。
図6及び図7は本発明の第2実施形態の電子部品実装構造の製造方法を示す断面図である。第2実施形態が第1実施形態と異なる点は、第1実施形態においてバンプを備えた電子部品をフェイスダウンで実装することにある。
第2実施形態では、電子部品20aのバンプ23が配線パターン12の接続パッド12xにフリップチップ接続されるので、電子部品20a上の層間絶縁層18にビアホールを形成する必要はない。その他の工程は第1実施形態と同一であるのでその説明を省略する。
図8〜図10は本発明の第3実施形態の電子部品実装構造の製造方法を示す断面図である。第3実施形態は、仮基板上に、第1実施形態と同様な方法で電子部品が層間絶縁層に埋設された構造を形成した後に、仮基板を除去し、層間絶縁層をコア基板として使用する形態である。第3実施形態では、第1実施形態と同一工程についてはその詳しい説明を省略する。
図11〜図13は本発明の第4実施形態の電子部品実装構造の製造方法を示す断面図である。第4実施形態は、第3実施形態においてバンプを備えていない電子部品をフェイスアップで実装する形態である。第4実施形態において第1〜第3実施形態と同一工程についてはその詳しい説明を省略する。
