Description
(a)素子が形成された半導体部分上に、コンタクト部のためのコンタクトホールを有する絶縁層を形成すること、
(b)電極パッドを、前記コンタクト部とオーバーラップする位置に窪み又は突起が残るように、前記絶縁層上に形成すること、
(c)前記電極パッドの第1の部分上に開口部を有するとともに、第2の部分上に載るように、パッシベーション膜を形成すること、
(d)前記電極パッド上にバリア層を形成すること、
(e)前記パッシベーション膜の前記開口部よりも大きく、前記パッシベーション膜上に一部が載るように、バンプを形成すること、
を含み、
前記コンタクト部を、前記バンプとオーバーラップする範囲内であって、前記電極パッドの前記第1の部分を避けて前記第2の部分に接続する。本発明によれば、コンタクト部を、電極パッドの第2の部分に接続する。これによって、電極パッドの窪み又は突起を、第2の部分に形成することができる。電極パッドの第2の部分上には、パッシベーション膜が載っているので、バリア層のバリア性能が当該窪み又は突起によって劣化するのを防止することができる。したがって、電極パッドに窪み又は突起が残るような、平坦化プロセスを省略したプロセスであっても、電気的な接続信頼性の向上を図ることができる。
(2)この半導体装置の製造方法において、
前記(b)工程で、前記電極パッド及び前記コンタクト部を同時に形成してもよい。
(3)この半導体装置の製造方法において、
前記(a)工程で、前記絶縁層の前記コンタクトホールの開口端部に、開口方向に広がるテーパ面を形成し、
前記(b)工程で、前記電極パッドの前記窪みを、前記テーパ面に従って形成してもよい。
(4)この半導体装置の製造方法において、
前記(b)工程で、前記コンタクト部を形成した後に、前記電極パッドを形成してもよい。
(5)この半導体装置の製造方法において、
前記(b)工程で、
(b1)前記コンタクト部を前記コンタクトホール内で凹部となるように形成し、
(b2)前記電極パッドの前記窪みを、前記コンタクト部による前記凹部に従って形成してもよい。
(6)この半導体装置の製造方法において、
前記(b)工程で、
(b1)前記コンタクト部を前記コンタクトホール上に凸部となるように形成し、
(b2)前記電極パッドの前記突起を、前記コンタクト部による前記凸部に従って形成してもよい。
(7)この半導体装置の製造方法において、
前記バンプは、前記半導体部分における前記素子の形成領域とオーバーラップしてもよい。
(8)この半導体装置の製造方法において、
前記(d)工程で、前記バリア層の一部を前記パッシベーション膜上に載るように形成し、
前記(e)工程で、前記電極パッドの前記第2の部分及び前記バンプの間に、前記パッシベーション膜及び前記バリア層を介在させてもよい。これによれば、第2の部分とバンプとの間には、パッシベーション膜だけでなくバリア層も介在している。そのため、電極パッド及びバンプの両者の拡散防止をより効果的に図ることができる。
(9)この半導体装置の製造方法において、
複数の前記コンタクト部を形成することを含み、
それぞれの前記コンタクト部を、前記バンプの中心軸を基準として対称に配列してもよい。これによって、実装プロセスなどにより、バンプを通じて伝達される機械的ストレスを均等に分散することができる。そのため、ストレス集中によるコンタクト部又は電極パッドなどの損傷を防止することができる。
