Description
また、かかるボイドの発生を抑えるためには高粘度のモールド樹脂が使用できず、生産性が低下するという問題もあった。
更に、真空状態でトランスファモールドを行なう真空モールドではボイドの発生を抑えられるが、真空装置等が必要となり、製造コストが高くなるという問題もあった。
図2は、ヒートスプレッダ1上に設けられた複数のディンプル10の上面図である。また、図3は、図2に含まれる1つのディンプル10の斜視図であり、図4は、図3をIII−III方向に見た場合の断面図である。。
また、隣接するディンプル10の間は、溝部14により連通されている。溝部14の深さは、第2底部12と同程度である。
かかる構造では、トランスファモールド法でヒートスプレッダ1を樹脂封止する場合、返り部13の下側にボイド(空気たまり)が発生しても、溝部14を通ってディンプル10の外にボイドを逃がすことができる。この結果、返り部13の下側にも、ボイドを発生させることなくモールド樹脂が充填でき、ヒートスプレッダ1とモールド樹脂9との密着性を向上させることができる。
溝部14の形成は、ディンプル10のプレス加工と別に行なってもよく、また同時に行なっても良い。
