Description
ウエーハに対して透過性を有する波長のレーザー光線を該分割予定ラインに沿って照射し、ウエーハの内部に該分割予定ラインに沿って変質層を形成する変質層形成工程と、
該変質層形成工程を実施した後に、環状のフレームに装着され紫外線が照射されると発熱して硬化することによって粘着力が低下する粘着テープの表面にウエーハの裏面を貼着するとともに、粘着テープの表面における該環状のフレームの内周とウエーハが貼着された領域との間の収縮領域に加熱されると収縮する性質を有する合成樹脂シートからなる環状の収縮部材を装着するウエーハ支持工程と、
該分割予定ラインに沿って変質層が形成されたウエーハが貼着されている該粘着テープに紫外線を照射し、該粘着テープの粘着力を低下せしめるとともに、該粘着テープにおける該環状のフレームの内周とウエーハが貼着された領域との間の収縮領域および該収縮領域に装着された該環状の収縮部材を収縮せしめることにより該変質層が形成された該分割予定ラインに沿ってウエーハを個々のチップに破断し且つ該チップ間の間隔を広げるチップ間隔形成工程と、を含む、
ことを特徴とするウエーハの分割方法が提供される。
この変質層形成行程は、先ず上述した図3に示すレーザー加工装置4のチャックテーブル41上に半導体ウエーハ2の保護部材3側を載置し(従って、半導体ウエーハ2は裏面2bが上側となる)、図示しない吸引手段によってチャックテーブル41上に半導体ウエーハ2を吸着保持する。半導体ウエーハ2を吸引保持したチャックテーブル41は、図示しない移動機構によって撮像手段43の直下に位置付けられる。
光源 :LD励起QスイッチNd:YVO4スレーザー
波長 :1064nmのパルスレーザー
パルス出力 :10μJ
集光スポット径 :φ1μm
繰り返し周波数 :100kHz
加工送り速度 :100mm/秒
即ち、粘着テープ50に貼着された半導体ウエーハ2(分割予定ライン21に沿って変質層210が形成されている)を柔軟なゴムシート上に載置し、その上面をローラーによって押圧することによって、半導体ウエーハ2を変質層210が形成され強度が低下した分割予定ライン21に沿って割断する方法を用いることができる。また、変質層210が形成され強度が低下した分割予定ライン21に沿って押圧部材を作用せしめる方法、或いは変質層210が形成され強度が低下した分割予定ライン21に沿ってレーザー光線を照射してヒートショックを与える方法等を用いることができる。
