Description
上記保護層は、非導電性無機材料で構成される。
上記接着剤層は、上記保護層の一方の面に設けられる。
また、保護層が非導電性無機材料で構成されているため、保護層が金属で構成される場合と比較して、ダイシング加工時における加工精度を向上させつつ、ダイシングソーの摩耗や劣化を抑制することができる。また、切り屑が半導体チップの回路面に付着したとしても短絡不良が生じることはない。これにより、生産性および信頼性の向上が図れることになる。
さらに、非導電性無機材料にガラス等の透光性を有する材料を用いることで、接着剤層表面にレーザー等で印字した場合にも、視認性を確保することが可能となる。
上記半導体素子は、上記配線基板にフリップチップ実装される。
上記保護フィルムは、非導電性無機材料で構成された保護層と、上記保護層の一方の面に設けられた接着剤層とを有し、上記接着剤層は上記半導体素子の裏面に接合される。
これにより、反りを抑制されたPoP構造等の半導体装置を得ることができる。
上記第1の半導体素子は、上記第1の配線基板にフリップチップ実装される。
上記第2の配線基板は、上記第1の半導体素子と上記第2の半導体素子との間に配置される。上記第2の配線基板は、保護層と、配線層と、接着剤層とを有する。上記保護層は、非導電性無機材料で構成される。上記配線層は、上記保護層に設けられ、上記第1の配線基板と上記第2の半導体素子との間を電気的に接続する。上記接着剤層は、上記保護層の一方の面に設けられ、上記第1の半導体素子の裏面に接合される。
上記保護フィルムは、非導電性無機材料で構成された保護層と、上記保護層の前記粘着層側とは反対側の面に設けられた接着剤層と、を有する。
図1は、本発明の一実施形態に係る半導体装置100の構成を示す概略側断面図、図2は、図1における要部(第1の半導体パッケージP1)の拡大図である。
各図において、X軸、Y軸及びZ軸は、相互に直交する3軸方向を示しており、Z軸方向は、半導体装置100の高さ方向(厚さ方向)に相当する。
図1に示すように、本実施形態の半導体装置100は、第1の半導体パッケージP1と第2の半導体パッケージP2との積層構造(PoP:Package on Package)を有する。
図3は、本発明の一実施形態に係る保護フィルム10を示す概略側断面図である。
なお、保護フィルム10は、第1の半導体チップC1の製造に用いられる半導体ウエハの裏面に貼着されたウエハサイズの保護フィルム10F(図6(A)参照)をチップレベルに切り出すことで形成される。なおまた、本発明に係る保護フィルムは、図1に示す半導体装置以外の半導体チップ用保護フィルムとして使用されることも、勿論可能である。
保護層11は、保護フィルム10の基材として構成される。保護層11は、非導電性無機材料で構成される。非導電性無機材料としては、ワークの加工、例えば半導体ウエハのダイシングに適するものであれば特に限定されず、典型的には、ガラス質材料、セラミック材料もしくはこれらの混合物などが挙げられる。
接着剤層12は、保護層11の一方の面に設けられる。接着剤層12は、典型的には、熱硬化性成分及びエネルギー線硬化性成分の少なくとも1種とバインダーポリマー成分とからなる。
図3に示すように、本実施形態の保護フィルム10は剥離シート13をさらに備える。剥離シート13は、接着剤層12を被覆するように設けられ、保護フィルム10の使用時には、接着剤層12から剥離される。
保護層11の少なくとも一方の面に印字層が設けられてもよい。印字層は、典型的には、文字、記号、図形等を含み、半導体素子あるいは半導体装置の種類等を識別可能に表示する。印字層は、典型的には、保護層11又は接着剤層12の少なくとも一部で構成され、例えば、接着剤層の保護層との接着側表面に形成される。印字層は、例えば、保護層11の表面をレーザー加工法等で削ることで形成されてもよいし、レーザー光の照射により接着剤層12表面を改質させることで形成されてもよい。特に、保護層11が板ガラス、透明セラミックス等、透光性を有する材料で構成される場合、保護層11に透光性が付与されるため、レーザー印字等により保護層の上から接着剤層12表面の印字層を容易に形成することができる。保護フィルム10は、印字層を別途有してもよい。すなわち、印字層は、保護層11及び接着剤層12とは異なる層で構成されてもよい。
続いて、保護フィルム10を備えた半導体装置、特に、第1の半導体パーケージP1の製造方法について説明する。
図8は、本発明の他の実施形態に係る半導体装置200の構成を示す概略側断面図である。以下、第1の実施形態と異なる構成について主に説明し、上述の実施形態と同様の構成については同様の符号を付しその説明を省略または簡略化する。
