Description
図1及び図2は本発明の第1実施形態の電子部品実装構造体の製造方法における電子部品を絶縁層に埋設して実装する際の基本プロセスを示す断面図、図3〜図5は同じく電子部品実装構造体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体の製造方法における電子部品を絶縁層に埋設して実装する際の基本プロセスを示す断面図、図8〜図10は同じく電子部品実装構造体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、基板上の配線パターンの上に下地絶縁層を形成した後に、粘性液状樹脂を形成することにあるので、第1実施形態と同一工程及び同一符号を付した同一要素についてはその詳しい説明を省略する。
図11及び図12は本発明の第3実施形態の電子部品実装構造体の製造方法を示す断面図である。第3実施形態の特徴は、第1実施形態において電子部品の接続端子(バンプ)を下側にした状態で(フェイスダウン)実装することにある。第1実施形態と同一工程及び同一符号を付した同一要素についてはその詳しい説明を省略する。
