Abstract
【解決手段】ボンディングワイヤ50の接合構造は、半導体素子10の電極10a上に形成されたバンプ上にボンディングワイヤを接合するボンディングワイヤの接合構造であって、ボンディングワイヤは、非貴金属を主成分とする芯材と、芯材を被覆する貴金属層とからなり、半導体素子の電極上に形成されたバンプ及びバンプ上にウエッジ接合されたボンディングワイヤが貴金属層を介して接合されていることを特徴とする。
【選択図】図1
Description
一方、このワイヤ剥がれを抑制するために、非貴金属ワイヤをバンプ上に接合する際のエネルギー(例えば、温度や超音波出力)を増加させると反対にワイヤ切れが発生してしまったり、半導体チップにダメージを与える虞がある。
本発明が解決しようとする課題は、非貴金属を主成分とするボンディングワイヤを使用した接合の信頼性を向上できるボンディングワイヤの接合構造及び接合方法を提供することである。
図1は、実施形態に係る半導体装置1の断面図である。以下、図1を参照して、実施形態に係る半導体装置1の構成について説明する。
実施形態に係る半導体装置1は、半導体チップ10(半導体素子)と、半導体チップ10を実装するための実装基板20とを備え、半導体チップ10が封止樹脂(モールド樹脂)30により封止された構造を有する。
図3A〜図3Cは、実施形態に係る半導体装置1が備える半導体チップ10の電極10aと実装基板20の表面配線20aとを接続するボンディング工程を説明するための図である。以下、図3A〜図3Cを参照して、半導体チップ10の電極10aと実装基板20の表面配線20aとのボンディング工程について説明する。
初めに、キャピラリ70に挿入されたボンディングワイヤ50の先端がスパークロッド80によりスパークされボール50aが形成される。
その後、キャピラリ70が半導体チップ10の電極10a上に下降し、電極10a上にバンプB1が形成・接合される。
バンプB1の接合後、ワイヤクランプ90がボンディングワイヤ50を挟持して上へ引き上げることによりボンディングワイヤ50が切断される。
切断されたボンディングワイヤ50の先端がスパークロッド80によりスパークされボール50aが形成される。
キャピラリ70が実装基板20の表面配線20a上に移動した後、下降して表面配線20a上にバンプB2が形成・接合される。
バンプB2が接合されると、キャピラリ70が半導体チップ10の電極10a上へ移動した後、半導体チップ10の電極10a上へ下降し、ボンディングワイヤ50が電極10a上に形成されたバンプB1へウエッジ接合される。
バンプB1へボンディングワイヤ50が接合されると、ワイヤクランプ90がボンディングワイヤ50を挟持して上へ引き上げることによりボンディングワイヤ50が切断される。
(第1の動作)
図4A,図4Bは、バンプB1を形成する際のキャピラリ70の第1の動作を示す説明図である。以下、図4A,図4Bを参照して、キャピラリ70の第1の動作について説明する。なお、図4A,図4Bでは、キャピラリ70の動作とバンプB1の形成を左側に記載し、キャピラリ70先端の軌跡を右側に記載した。また、図4A、4B右側のカッコ内の数字は、キャピラリ70の動作の順序を表している。
キャピラリ70が半導体チップ10の電極10a上に下降して、電極10a上にバンプB1を形成・接合した後、キャピラリ70が上昇する。
キャピラリ70が、接続先である実装基板20の表面配線20aとは反対側(図4Aでは右側)に水平移動する。
キャピラリ70が半導体チップ10の電極10a上に下降して、キャピラリ70先端の左側でボンディングワイヤ50を上記第1工程で接合したバンプB1上面に、ボンディングワイヤ50を折りたたむようにして押圧・接合する。
図示しないワイヤクランプがボンディングワイヤ50を挟持した状態で、キャピラリ70が上昇してボンディングワイヤ50が切断される。
図5Aは、図4A、図4Bを参照して説明した第1の動作で形成したバンプB1のSEM画像である。図5Bは、図4A、図4Bを参照して説明した第1の動作で形成したバンプB1の拡大図である。なお、図5Bでは、バンプB1を、芯材50aを被覆する貴金属層50bが存在する部分を太い実線で記載し、貴金属層50bが存在しない部分を破線で記載した。
図6A,図6Bは、バンプB1を形成する際のキャピラリ70の第2の動作を示す説明図である。以下、図6A,図6Bを参照して、キャピラリ70の第2の動作について説明する。なお、図6A,図6Bでは、キャピラリ70の動作とバンプB1の形成を左側に記載し、キャピラリ70先端の軌跡を右側に記載した。また、図6B右側のカッコ内の数字は、キャピラリ70の動作の順序を表している。
キャピラリ70が半導体チップ10の電極10a上に下降して、電極10a上にバンプB1を形成・接合した後、キャピラリ70が上昇する。
キャピラリ70が、接続先である実装基板20の表面配線20aの方向(図5Aでは左側)に水平移動する。
キャピラリ70が半導体チップ10の電極10a上に下降して、キャピラリ70先端の右側でボンディングワイヤ50を上記第1工程で接合したバンプB1上面に、ボンディングワイヤ50を折りたたむようにして押圧・接合する。
キャピラリ70が上昇した後、接続先である実装基板20の表面配線20aと反対側(図5Bでは右側)に水平移動する。
キャピラリ70が半導体チップ10の電極10a上に下降して、キャピラリ70先端の左側でボンディングワイヤ50を上記第3工程で接合したボンディングワイヤ50上に、更にボンディングワイヤ50を折りたたむようにして押圧・接合する。
図示しないワイヤクランプがボンディングワイヤ50を挟持した状態で、キャピラリ70が上昇してボンディングワイヤ50が切断される。
図7Aは、図6A、図6Bを参照して説明した第2の動作で形成したバンプB1のSEM画像である。図7Bは、図6A、図6Bを参照して説明した第2の動作で形成したバンプB1の拡大図である。なお、図7Bでは、バンプB1を、芯材50aを被覆する貴金属層50bが存在する部分を太い実線で記載し、貴金属層50bが存在しない部分を破線で記載した。
ここでは、バンプB1形成後のボンディングワイヤ50の切断方法について図8を参照して説明する。初めに、図8(a)について説明する。なお、図8(a)右側のカッコ内の数字は、キャピラリ70の動作の順序を表している。また、図8(a)に示す(1)から(4)までの動作は、図4A(a)から図4A(c)を参照して説明した第1工程から第3工程の動作と同じであるため重複した説明を省略する。
実施形態では、実施形態に係る半導体装置1(図1参照)では、実装基板20の表面配線20aからルーピングされたボンディングワイヤ50を、半導体チップ10の電極10a上に形成したバンプB1へウエッジ接合する形態について説明したが、他の接合形態にも適用が可能である。
