Abstract
Description
図1は、第1実施形態によるボンディング装置1の構成例を示す概略断面図である。半導体製造装置としてのボンディング装置1は、ステージ10と、ボンディングツール20と、を備えている。ボンディング装置1は、ステージ10上に載置された配線基板SUB上に半導体チップCHPを搭載し、加圧および加熱することによって半導体チップCHPの電極ELDをバンプBMPで配線基板SUBのリード電極LELに電気的に接続する。尚、ボンディングツール20の押圧方向(ステージ10の搭載面に対して略垂直方向)がZ方向であるとする。Z方向に対して垂直面の一方向をX方向とし、X方向に直交する方向をY方向とする。
図5は、第2実施形態によるボンディング装置1の構成例を示す概略断面図である。図6は、第2実施形態によるボンディング装置1の構成例を示す概略平面図である。図5は、図6のB-B線に沿った断面に対応する。尚、図5および図6は、ボンディングツール20がすでに半導体チップCHPを配線基板SUBへ押圧しているときの様子を示している。また、図6において、半導体チップCHPの位置は、仮想線で示されている。
図7は、変形例によるボンディング装置1の構成例を示す概略平面図である。第1および第2実施形態では、切欠き部23a、23bは、図2、図4および図6に示すように、保持面F20の外縁に沿って互い違いに(半ピッチずらして)設けられている。しかし、図7に示すように、切欠き部23a、23bは、Z方向から見たときに、保持面F20の外縁の各辺においてX方向またはY方向にほぼ同一ピッチで配置され、揃っていてもよい。この場合、X方向またはY方向から見たときに、切欠き部23a、23bは、互いに揃っており、外部から半導体チップCHPを収容する空間へ連通している。このような構成であっても、本実施形態の効果は失われない。
