Description
半導体チップと、
前記半導体チップが搭載された配線基板と、
前記配線基板に設けられた複数の外部端子と、
を含み、
前記複数の外部端子は、少なくとも1つの第1の外部端子と、2以上の第2の外部端子とを含み、
前記第1の外部端子は、ろう材からなり、
前記第2の外部端子は、ろう材と前記ろう材中に分散され樹脂からなる複数の粒子とを含み、
前記複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対が前記第2の外部端子となっている。本発明によれば、複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対が第2の外部端子となっている。第2の外部端子は複数の粒子を含むので、これによって、第2の外部端子に加えられる応力を緩和することができる。複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対には、配線基板の膨張又は収縮による応力が最も加えられる。したがって、かかる部分に第2の外部端子を配置することによって、応力を効果的に緩和することができる。
(2)この半導体装置において、
前記複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された複数対が前記第2の外部端子となっていてもよい。
(3)この半導体装置において、
前記複数の外部端子の配列領域の外形は四辺形をなし、
前記第2の外部端子は、前記四辺形の角部の領域に配置されていてもよい。これによれば、四辺形の角部に加えられる応力を効果的に緩和することができる。
(4)本発明に係る半導体装置は、
第1の半導体チップを含む第1の半導体装置と、
第2の半導体チップを含む第2の半導体装置と、
前記第1の半導体装置と前記第2の半導体装置の間に介在し、両者を電気的に接続する複数の外部端子と、
を含み、
前記複数の外部端子は、少なくとも1つの第1の外部端子と、2つ以上の第2の外部端子とを含み、
前記第1の外部端子は、ろう材からなり、
前記第2の外部端子は、ろう材と前記ろう材中に分散され樹脂からなる複数の粒子とを含み、
前記複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対が前記第2の外部端子となっている。本発明によれば、複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対が第2の外部端子となっている。第2の外部端子は複数の粒子を含むので、これによって、第2の外部端子に加えられる応力を緩和することができる。複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対には、配線基板の膨張又は収縮による応力が最も加えられる。したがって、かかる部分に第2の外部端子を配置することによって、応力を効果的に緩和することができる。
(5)本発明に係る半導体装置は、
第1の半導体チップを含む複数の第1の半導体装置と、
第2の半導体チップを含み、それぞれの前記第1の半導体装置が互いにオーバーラップしないように搭載された第2の半導体装置と、
前記第1の半導体装置と前記第2の半導体装置の間に介在し、両者を電気的に接続してなり、前記第1の半導体装置に対応した複数グループからなる複数の外部端子と、
を含み、
前記複数の外部端子は、少なくとも1つの第1の外部端子と、2以上の第2の外部端子とを含み、
前記第1の外部端子は、ろう材からなり、
前記第2の外部端子は、ろう材と前記ろう材中に分散され樹脂からなる複数の粒子とを含み、
前記複数の外部端子の各グループの配列領域の外形は長方形をなし、
少なくとも1つのグループのうち、前記長方形の対向する角部の領域に配置された一対が前記第2の外部端子となっている。本発明によれば、複数の外部端子のうち、配列領域の長方形の対向する角部の領域に配置された一対が第2の外部端子となっている。第2の外部端子は複数の粒子を含むので、これによって、第2の外部端子に加えられる応力を緩和することができる。複数の外部端子のうち、配列領域の長方形の対向する角部の領域に配置された一対には、配線基板の膨張又は収縮による応力が最も加えられる。したがって、かかる部分に第2の外部端子を配置することによって、応力を効果的に緩和することができる。
(6)本発明に係る半導体装置は、
第1の半導体チップを含む複数の第1の半導体装置と、
第2の半導体チップを含み、それぞれの前記第1の半導体装置が互いにオーバーラップしないように搭載された第2の半導体装置と、
前記第1の半導体装置と前記第2の半導体装置の間に介在し、両者を電気的に接続してなり、前記第1の半導体装置に対応した複数グループからなる複数の外部端子と、
を含み、
前記複数の外部端子は、少なくとも1つの第1の外部端子と、2以上の第2の外部端子とを含み、
前記第1の外部端子は、ろう材からなり、
前記第2の外部端子は、ろう材と前記ろう材中に分散され樹脂からなる複数の粒子とを含み、
前記複数の外部端子の各グループの配列領域の外形は長方形をなし、
少なくとも1つのグループのうち、前記長方形の各短辺に沿った領域の端部に配置された一対が前記第2の外部端子となっている。本発明によれば、複数の外部端子のうち、配列領域の長方形の短辺に沿った領域に配置された一対が第2の外部端子となっている。第2の外部端子は複数の粒子を含むので、これによって、第2の外部端子に加えられる応力を緩和することができる。複数の外部端子のうち、配列領域の長方形の短辺に沿った領域に配置された一対には、配線基板の膨張又は収縮による応力が加えられやすい。したがって、かかる部分に第2の外部端子を配置することによって、応力を効果的に緩和することができる。
(7)この半導体装置において、
前記第1の半導体装置は、
前記第1の半導体チップがフェースアップ実装された第1の配線基板と、
前記第1の半導体チップを封止する樹脂封止部と、
をさらに含んでもよい。これによれば、第1の半導体装置が樹脂封止部を有する場合、第1の半導体装置と第2の半導体装置の間の熱膨張率の差が大きくなるため、外部端子に応力が加えられやすいのでより効果的である。
(8)この半導体装置において、
前記第2の半導体装置は、前記第2の半導体チップがフェースダウン実装された第2の配線基板をさらに含み、
前記複数の外部端子は、前記第2の半導体チップの外側の領域に配列されていてもよい。
(9)この半導体装置において、
前記第2の外部端子に隣接する外部端子は、前記第2の外部端子と同一の構成を有してもよい。これによれば、より効果的に応力を緩和することができる。
(10)この半導体装置において、
前記第2の外部端子は、それぞれの前記粒子の表面をコーティングしてなる導体皮膜をさらに含んでもよい。これによれば、粒子の表面が導体皮膜によってコーティングされているので、第2の外部端子の電気的特性の向上を図ることができる。例えば、複数の粒子が密集しても導体皮膜同士が接触するため、粒子間にも電気が流れることになり、絶縁部分の拡大を防止することができる。
(11)この半導体装置において、
前記粒子は、熱硬化されていてもよい。これによれば、第2の外部端子を加熱溶融したときに、粒子が溶融することがない(又は溶融しにくい)ので、加熱溶融後も複数の粒子が分散した状態を維持することができる。したがって、加熱溶融後も第2の外部端子の応力緩和を図ることができる。
(12)本発明に係る回路基板は、上記半導体装置が搭載されてなる。
(13)本発明に係る電子機器は、上記半導体装置を有する。
(14)本発明に係る半導体装置の製造方法は、
半導体チップが搭載された配線基板に複数の外部端子を設けることを含み、
前記複数の外部端子は、少なくとも1つの第1の外部端子と、2以上の第2の外部端子とを含み、
前記第1の外部端子をろう材で形成し、
前記第2の外部端子をろう材中に樹脂からなる複数の粒子を分散させることによって形成し、
前記複数の外部端子を、他のいずれの一対よりも互いに離れて配置した一対が前記第2の外部端子となるように設ける。本発明によれば、複数の外部端子を、他のいずれの一対よりも互いに離れて配置された一対が第2の外部端子となるように設ける。第2の外部端子は複数の粒子を含むので、これによって、第2の外部端子に加えられる応力を緩和することができる。複数の外部端子のうち、他のいずれの一対よりも互いに離れて配置された一対には、配線基板の膨張又は収縮による応力が最も加えられる。したがって、かかる部分に第2の外部端子を配置することによって、応力を効果的に緩和することができる。
