Description
ところで、上記実施形態において、ヒートシンクブロック50の一面51または他面52に、迎えはんだを行うとき、はんだ付けしたくない部分すなわちヒートシンクブロック50の側面にまではんだ40が濡れてしまう恐れがある。この場合、ショートなどの問題が発生しやすくなる。
40…はんだ、41…スペーサ、
50…金属体としてのヒートシンクブロック、
51…ヒートシンクブロックの一面、52…ヒートシンクブロックの他面。
Claims (3)
- 一面(11)がはんだ付けされるはんだ付け領域とはんだ付けされない非はんだ付け領域とに分割されている半導体素子(10)と、
一面(51)が前記はんだ付け領域と同等以下のサイズである金属体(50)とを用意し、
前記半導体素子(10)の前記一面(11)における前記はんだ付け領域に対して、はんだ(40)を介して前記金属体(50)の前記の一面(51)を接合するようにした半導体装置の製造方法において、
前記金属体(50)の前記一面(51)に予め前記はんだ(40)をはんだ付けしておき、次に、前記はんだ(40)を介して前記半導体素子(10)の前記一面(11)と前記金属体(50)の前記一面(51)と位置あわせし、その後、前記はんだ(40)をリフローさせて前記半導体素子(10)と前記金属体(50)とを接合することを特徴とする半導体装置の製造方法。 - 前記はんだ付け領域は、複数の分割された分割部(14)よりなるものであり、
前記金属体(50)の前記一面(51)に予めはんだ付けされる前記はんだ(40)を、前記複数の分割部(14)のすべてに重なる大きさとすることを特徴とする請求項1に記載の半導体装置の製造方法。 - 前記はんだ(40)として、前記はんだ(40)のリフロー時に、前記半導体素子(10)の前記一面(11)と前記金属体(50)の前記一面(51)との傾きを防止するスペーサ(41)が混合しているものを、前記金属体(50)の前記一面(51)に予めはんだ付けすることを特徴とする請求項1または2に記載の半導体装置の製造方法。
