【選択図】図2
Description
このような構造のパッケージングにおいては、半導体チップの端子増加に伴う端子リードの狭ピッチ化に対し、基板に実装できる数の限界があることから、必要な端子リードの間隔を維持するためにパッケージの大型化を避けることが困難であるという課題があった。
こうした課題に対して、チップ・サイズ・パッケージと呼ばれるパッケージをはじめとする、ソルダーおよびバンプを用いたボンディング部分を有するチップがある。
図1は、本発明の一実施形態による半導体装置の断面図である。半導体装置20は、配線層(Al配線)3と、応力緩和層4と、ポスト6とを備える。本実施形態においては、半導体装置20は、半導体チップ1を備える。このチップ1は、実装基板(不図示)と接続される側の表面にゲート電極(不図示)およびソース電極(不図示)を備え、裏面にドレイン電極(不図示)を備える。ドレイン電極の裏面メタル9は、半田8を介して導電性キャップ2に接続されている。導電性キャップ2を、チップ1の裏面に形成されたドレイン電極と実装基板(不図示)とを電気的に接続する電極として用いる場合は、図6のような脚部46(図1では不図示)を設けると良い。ゲート電極およびソース電極の配線層(Al配線)3上には、アレイ状の開口部を有する応力緩和層4が設けられる。応力緩和層4は、Al配線層3の少なくとも一部を露出させる開口を有し、このAl配線層3を覆うように形成される。応力緩和層4上には、この開口を覆うとともに、開口周囲の応力緩和層4とオーバーラップするようにUBM層5が設けられ、このUBM層5の上には、Cuポスト6が設けられる。本実施形態において、UBM層5とCuポスト6とは同じ径を有する。Cuポスト6間は、エポキシ樹脂層10で覆われる。Cuポスト6の上には、半田ボール7が搭載される。
半導体チップ1には、MOSFET(不図示)や層間絶縁膜(不図示)などが形成されており、その上にAl配線層3を備えている。まず、Al配線層3全体を覆う応力緩和層4を、CVD法により形成する。このように形成された応力緩和層4をパターニングし、直径(B)を有する開口部を、例えばアレイ状に設ける。次いで、開口部を含む応力緩和層4全体を覆うように、UBM層5をスパッタ法等により形成する。UBM層5の材料としては、チタン(Ti)、銅(Cu)またはニッケル(Ni)、あるいはこれらの合金を使用することができる。その後、UBM層5上の、Cuポスト6を形成する予定の領域に、予め穴を開けたドライフィルム(不図示)を貼り付ける。その後、電界メッキにより、UBM層5の上にCuポスト6を形成する。その後、ドライフィルムを剥がし、Cuポスト6をマスクとしてUBM層5をエッチングし、余分なUBM層5を除去する。これにより、UBM層5は、Cuポスト6とほぼ同形となるように加工される。その後、Al配線層3、応力緩和層4、UBM層5、およびCuポスト6を被覆するように、エポキシ樹脂層10を形成する。その後、エポキシ樹脂層10を研磨して、Cuポスト6の表面をエポキシ樹脂層10から露出させる。したがって、Cuポスト6の露出面とエポキシ樹脂層10の表面とは、ほぼ同一平面をなす。その後、Cuポスト6の上に半田ボール7を形成する。
C=B+2×A ・・・式(1)
図3にはまた、UBM層5の直径およびCuポスト6の直径(C)を0.5mmとし、応力緩和層4としてリンガラスを用いた場合の、応力緩和層4の開口寸法(B)と、Al配線層3にかかる最大応力のシミュレーション結果を示す。図3から、応力緩和層4とCuポスト6との間のオーバーラップ部分の寸法2A(ただし、2A=C−B)を大きくするにつれて、Al配線層3にかかる最大応力が小さくなるのが分かる。図3に示される結果から、オーバーラップ部分の寸法2Aを直径Cに対して10%程度とすることで、オーバーラップ部分を設けない場合と比較して、Al配線層3にかかる最大応力を約25%低減することができる。なお、最大応力が500MPaより小さい場合には、Cuポスト6直下の破壊は起こらないことが実験的に判っている。
上記の値が0.1以上であると、実装時の応力緩和が十分であり、0.5以下であるとCuポストとAl配線層との間の抵抗を低く維持できる。
なお、本実施形態では、応力緩和層4の開口寸法Bに対して、Cuポスト6が同心円状に重なる例を示したが、通常は、応力緩和層4の開口部に対してドライフィルムの貼り合わせ位置はずれるため、Cuポスト6の中心と応力緩和層4の開口部の中心はずれる。この場合は、オーバーラップ部分の最小寸法および最大寸法をそれぞれAminおよびAmaxとしたとき、(Amin+Amax)を上記の(2A)に置き換えて考えればよい。
また、本実施形態では、UBM層5とCuポスト6とがほぼ同形となる例を示したが、UBM層5はCuポスト6よりも広くなるようにパターニングしても良い。
また、本実施形態では、エポキシ樹脂層10を用いたが、ポリイミド樹脂などの他の熱硬化性樹脂を用いることができる。
図4は、本実施形態による半導体装置の概略図である。本実施形態における半導体装置は、応力緩和層4の複数個の開口部にわたり、UBM層5およびCuポスト6が設けられている以外は、第一の実施形態と同様である。
ただし、
C'=2×A'+A''+2×B'
である。
例えば、導電性キャップ2を設けた半導体素子20を例に説明したが、本発明は、導電性キャップ2が無い場合にも適用できる。また、半導体装置20を実装基板に接続した場合を例に説明したが、本発明は、熱膨張係数が同じ半導体装置に対してバンプ接合する場合にも適用できる。
