本発明による半導体装置の製造方法について、以下に説明する。此処では、前記半導体装置40、半導体装置130、半導体装置135並びに半導体装置140の製造方法を主体に説明する。
本発明による半導体装置の、第1の基本例に係る半導体装置40(図5参照)の製造方法について、図29乃至図32を参照して説明する。
当該第1の半導体チップ42を配線基板41上に固着する第1の接着剤43としては、例えば、熱硬化性又は熱可塑性の絶縁性樹脂接着剤を用いることができ、具体的には、エポキシ系、ポリイミド系、アクリル系、又はシリコン系等の樹脂を用いることができる。当該第1の接着剤43は、フィルム状のものを予め第1の半導体チップ42の背面に形成しておいてもよく、また予め配線基板41上に塗布してもよい。
一方、予め電極パッド48にバンプ51が形成された第2の半導体チップ44を、加熱したボンディングツール305に、吸着孔310を介して吸着保持する。
かかる加熱温度として、ボンディングツール305側の温度を約250℃乃至300℃に設定し、また、配線基板41側の温度を約50℃乃至100℃に設定することができる。一方、印加荷重として、例えば約5gf/bump乃至30gf/bumpを選択することができる。
このとき、加熱温度を120℃乃至180℃に設定することができ、また、加熱時間を約30分乃至90分に設定することができる。
しかる後、配線基板41の他方の主面(裏面)に、外部接続用端子を構成する半田ボール49を複数個配設し、半導体装置40を形成する。(図32(g)参照)
この様に、本製造方法によれば、第1の半導体チップ42上に第2の半導体チップ44を固着する際に、同時に当該第2の半導体チップ44の電極パッド48と配線基板41に於けるボンディングパッド47−2とをバンプ51を介して接続することができる。加えて、当該第2の接着剤45により、バンプ51の周囲を被覆することができる。従って、簡易な方法により、半導体装置40を形成することができる。
本発明による半導体装置の、第2の基本例に係る半導体装置130(図15参照)の製造方法について、図33、図34、及び図38乃至図40を参照して説明する。
一方、第2の半導体チップ44の電子回路形成面に設けられた電極パッド48上には、バンプ51を配設する。当該バンプ51は、前述の如くボールボンディング法により形成することができる。(図33(b)参照)
しかる後、ボンディングステージ(図示せず)に吸着保持された第2の半導体チップ44の電子回路形成面上に、ボンディングツール305に吸着保持された第1の半導体チップ42の電子回路形成面を対向させ、且つ、第2の半導体チップ44の電極パッド48と第1の半導体チップ42の電極パッド46が夫々露出するように位置決めする。
かかる構成により、バンプ51と第2のボンディングパッド47−2との接続のために、当該ボンディングパッド47−2を厚く形成する必要が無く、ボンディングパッド47−2の設計の自由度が向上する。
しかる後、第1の接着剤43を加熱・硬化する。このとき、ボンディングツール305側の加熱温度を約250℃乃至300℃に設定しても良く、基板側の加熱温度を約50℃乃至100℃に設定してもよい。更に、印加する荷重として、例えば、約5gf/bump乃至30gf/bumpと設定してもよい。
この工程では、加熱温度を120℃乃至180℃に設定することができ、また、加熱時間を、約30分乃至90分に設定することができる。
次いで、トランスファー樹脂モールド法等により、配線基板41の主面上に於ける半導体チップ等を封止樹脂52により封止樹脂する。(図40(h)参照)
しかる後、前記配線基板41の他方の主面(裏面)に、外部接続用端子を構成する半田ボール49を複数個配設し、半導体装置130を形成する。(図40(i)参照)
このように、本製造方法によれば、第1の半導体チップ42を配線基板41へ固着する際適用される第1の接着剤43によって、第2の半導体チップ44のバンプ51と配線基板41に於けるボンディングパッド47−2との接続部の周囲を被覆することができる。従って、簡易な方法により半導体装置130を製造することができる。
本発明による半導体装置の、第3の基本例に係る半導体装置135(図16参照)の製造方法について、図41乃至図44を参照して説明する。
当該第1の接着剤43としては、例えば熱硬化性又は熱可塑性の絶縁性樹脂接着剤を用いることができ、具体的には、エポキシ系、ポリイミド系、アクリル系、又はシリコン系等の樹脂を用いることができる。当該第1の接着剤43は、フィルム状のものを予め第1の半導体チップ42の背面に被着しておいてもよく、或いは配線基板41上に予め塗布形成しておいてもよい。
次いで、予め第2の電極パッド48にバンプ51を形成した第2の半導体チップ44を、加熱したボンディングツール305に、吸着孔310を介して吸着保持し、バンプ51とボンディングステージ(図示せず)に吸着保持された配線基板41の第2のボンディングパッド47−2とが対向するように位置合わせする。
この時、加熱温度として、ボンディングツール305側の温度を約250℃乃至300℃に設定してもよく、基板側の温度を約50℃乃至100℃に設定してもよい。更に、印加する荷重として、約1gf/bump乃至8gf/bumpを設定してもよい。
この工程にあっては、加熱温度を120℃乃至180℃に設定することができ、また、加熱時間を約30分乃至90分に設定することができる。
次いで、恒温槽(図示せず)に於いて構造全体を加熱し、第3の接着剤133を完全に硬化せしめ、第2の半導体チップ44と配線基板41とのフリップチップ接続を完了する。(図43(f)参照)
この工程にあっては、加熱温度を、120℃乃至180℃に設定することができ、加熱時間を、約30分乃至90分に設定することができる。
次いで、トランスファー樹脂モールド法等により、配線基板41の上方を封止樹脂52により封止樹脂する。(図44(h)参照)
しかる後、配線基板41の他方の主面(裏面)に、外部接続用端子を構成する半田ボール49を複数個配設し、半導体装置135を形成する。(図44(i)参照)
このように、本製造方法にあっては、第3の接着剤133により、配線基板41と第2の半導体チップ44との接続と、バンプ51及び導電材131の周囲の被覆を行っている。従って、前記半導体装置130又は135の製造方法に比べ、バンプ51及び導電材131の周囲を補強するに好適な材料を設定することができる。
本発明による半導体装置の第4の基本例に係る半導体装置140(図17参照)の製造方法について、図41乃至図42及び図45を参照して説明する。
次いで、トランスファー樹脂モールド法等により、前記配線基板41の一方の主面上に搭載された半導体チップ等を封止用樹脂52により被覆し、樹脂封止する。このとき、第2の半導体チップ44と配線基板41との間にあって、バンプ51及び導電材131の周囲も当該封止用樹脂52により被覆される。(図45(b)参照)
しかる後、配線基板41の他方の主面(下面)に、外部接続用端子47を構成する半田ボールを複数個配設して、半導体装置140を形成する。(図45(c)参照)
この様な製造方法あっては、封止用樹脂52を接着剤として適用することにより、第2の半導体チップ44と配線基板41との間に接着剤を配設する必要がなく、より簡易な工程により、半導体装置140を製造することができる。
