Description
それぞれの前記第1のパッドと前記配線パターンとをワイヤで電気的に接続すること、
前記第1の半導体チップ上に樹脂ペーストを設けること、
複数の第2のパッドが形成されてなる第2の半導体チップを、前記第1のパッドと間隔をあけてオーバーラップするように、前記樹脂ペーストを介して前記第1の半導体チップに搭載すること、及び、
前記樹脂ペーストを硬化させて、前記第1の半導体チップと前記第2の半導体チップとの間にスペーサを形成し、前記第1及び第2の半導体チップを固着することを含み、
前記スペーサを、前記第2のパッドの下よりも外側に至るように形成し、
前記ワイヤを、最も高い部分が前記第1の半導体チップの外側に配置されるように設ける。本発明によれば、スペーサを、第2の半導体チップの第2のパッドの下よりも外側に至るように形成する。そのため、第2のパッドに負荷をかけた場合でも、第2の半導体チップを割れにくくすることができる。また、ワイヤを、最も高い部分が第1の半導体チップの外側に配置されるように設ける。すなわち、第1の半導体チップ上で、ワイヤの高さを低くすることができる。これにより、樹脂ペーストが流動した場合でも、ワイヤが移動しにくくなるためワイヤ同士のショートを防止することができる。これらのことから、信頼性の高い半導体装置を製造することができる。
(2)本発明に係る半導体装置の製造方法は、複数の第1のパッドが形成されてなる第1の半導体チップが搭載された、配線パターンを有する配線基板を用意すること、
それぞれの前記第1のパッドと前記配線パターンとをワイヤで電気的に接続すること、
前記第1の半導体チップ上に樹脂ペーストを設けること、
複数の第2のパッドが形成されてなる第2の半導体チップを、前記第1のパッドと間隔をあけてオーバーラップするように、前記樹脂ペーストを介して前記第1の半導体チップに搭載すること、及び、
前記樹脂ペーストを硬化させて、前記第1の半導体チップと前記第2の半導体チップとの間にスペーサを形成し、前記第1及び第2の半導体チップを固着することを含み、
前記スペーサを、前記第2のパッドの下よりも外側に至るように形成し、
前記ワイヤを、前記第1の半導体チップ上の空間から斜め上方に突出するように設ける。本発明によれば、スペーサを、第2の半導体チップの第2のパッドの下よりも外側に至るように形成する。そのため、第2のパッドに負荷をかけた場合でも、第2の半導体チップを割れにくくすることができる。また、ワイヤを、第1の半導体チップ上の空間から斜め上方に突出するように設ける。すなわち、第1の半導体チップ上の空間で、ワイヤの高さを低くすることができる。これにより、樹脂ペーストが流動した場合でも、ワイヤが移動しにくくなるためワイヤ同士のショートを防止することができる。これらのことから、信頼性の高い半導体装置を製造することができる。
(3)この半導体装置の製造方法において、
前記樹脂ペーストを、前記第1の半導体チップから前記配線基板上に流出させ、前記第1の半導体チップの周囲にフィレットを形成することをさらに含んでもよい。これによれば、配線基板における第1の半導体チップの周囲にフィレットが形成される。そのため、フィレットによって第1の半導体チップ及び配線基板を保護された、信頼性の高い半導体装置を製造することができる。
(4)この半導体装置の製造方法において、
前記樹脂ペーストを設ける工程で、前記第1の半導体チップ上のみに前記樹脂ペーストを設け、
前記第2の半導体チップを搭載する工程で、前記樹脂ペーストが前記配線基板上に流出するように前記第2の半導体チップを搭載してもよい。

(7)この半導体装置の製造方法において、
前記ワイヤで電気的に接続する工程は、
前記ワイヤと前記第1のパッドとを電気的に接続すること、及び、その後、
前記ワイヤと前記配線パターンとを電気的に接続することを含んでもよい。
(8)この半導体装置の製造方法において、
前記樹脂ペーストを硬化させる工程の後に、前記第2のパッドと前記配線パターンとを他のワイヤで電気的に接続することをさらに含んでもよい。
(9)本発明に係る半導体装置は、配線パターンが形成された配線基板と、
前記配線基板に搭載された、複数の第1のパッドが形成されてなる第1の半導体チップと、
前記配線パターンとそれぞれの前記第1のパッドとを電気的に接続するワイヤと、
前記第1のパッドと間隔をあけてオーバーラップするように前記第1の半導体チップに搭載された、複数の第2のパッドが形成されてなる第2の半導体チップと、
前記第1の半導体チップと前記第2の半導体チップとの間に形成された、前記第1及び第2の半導体チップを固着するスペーサと、
を含み、
前記スペーサは、前記第2のパッドの下よりも外側に至るように形成されてなり、
前記ワイヤは、最も高い部分が前記スペーサの外側に配置されるように設けられている。本発明によれば、スペーサは、第2の半導体チップの第2のパッドの下よりも外側に至るように形成される。そのため、第2のパッドに負荷をかけた場合でも、第2の半導体チップを割れにくくすることができる。また、ワイヤは、最も高い部分がスペーサの外側に配置されるように設けられてなる。すなわち、第1の半導体チップ上で、ワイヤの高さを低くすることができる。そのため、スペーサの厚みを薄くすることができる。これらのことから、信頼性が高く、実装性に優れた半導体装置を提供することができる。
(10)本発明に係る半導体装置は、配線パターンが形成された配線基板と、
前記配線基板に搭載された、複数の第1のパッドが形成されてなる第1の半導体チップと、
前記配線パターンとそれぞれの前記第1のパッドとを電気的に接続するワイヤと、
前記第1のパッドと間隔をあけてオーバーラップするように前記第1の半導体チップに搭載された、複数の第2のパッドが形成されてなる第2の半導体チップと、
前記第1の半導体チップと前記第2の半導体チップとの間に形成された、前記第1及び第2の半導体チップを固着するスペーサと、
を含み、
前記スペーサは、前記第2のパッドの下よりも外側に至るように形成されてなり、
前記ワイヤは、前記スペーサから斜め上方に向かって突出するように設けられている。本発明によれば、スペーサは、第2の半導体チップの第2のパッドの下よりも外側に至るように形成される。そのため、第2のパッドに負荷をかけた場合でも、第2の半導体チップを割れにくくすることができる。また、ワイヤは、スペーサから斜め上方に向かって突出するように設けられてなる。すなわち、第1の半導体チップ上で、ワイヤの高さを低くすることができる。そのため、スペーサの厚みを薄くすることができる。これらのことから、信頼性が高く、実装性に優れた半導体装置を提供することができる。
(11)この半導体装置において、
前記配線基板上で前記第1の半導体チップの周囲に配置されたフィレットをさらに有してもよい。これによれば、フィレットによって、第1の半導体チップ及び配線基板が外力により受ける影響を小さくすることができる。そのため、さらに信頼性の高い半導体装置を提供することができる。
(12)この半導体装置において、
前記スペーサと前記フィレットとは同じ材料であってもよい。
(13)この半導体装置において、
前記スペーサは、内部に絶縁性のボールを有してもよい。
(14)本発明に係る回路基板には、上記半導体装置が実装されている。
(15)本発明に係る電子機器は、上記半導体装置を有する。
本発明は、以上の実施の形態に限られず、種々の変形が可能である。例えば、半導体装置の製造方法は、樹脂ペースト40を、第1の半導体チップ10から配線基板20上に流出させて、第1の半導体チップ10の周囲にフィレット65を形成することをさらに含んでもよい(図11(B)参照)。樹脂ペースト40を設ける工程で、第1の半導体チップ10上のみに樹脂ペースト40を設け(図3参照)、第2の半導体チップ50を搭載する工程で、樹脂ペースト40が配線基板20上に流出するように第2の半導体チップ50を搭載してもよい(図11(A)参照)。ただしこれとは別に、樹脂ペースト40を設ける工程で、第1の半導体チップ10から配線基板20上に流出するように、樹脂ペースト40を設けてもよい。そして、樹脂ペースト40を硬化させて、スペーサ60及びフィレット65を形成してもよい(図11(B)参照)。このとき、フィレット65は、配線基板20上で第1の半導体チップ10の周囲に配置される。また、フィレット65及びスペーサ60は、同じ材料で形成される。本変形例によれば、配線基板20上で半導体チップ10の周囲にフィレット65が形成される。そして、フィレット65によって第1の半導体チップ10が保護された、さらに信頼性の高い半導体装置を製造することができる。特に、外力に対する信頼性の高い半導体装置を製造することができる。また、ここに説明した方法によれば、フィレット65を形成する工程を別途設ける必要がないため、効率よく半導体装置を製造することができる。
