Abstract
Description
SiO2膜に残存するO-H結合またはC-H結合の伸縮振動による吸収率の高い波長のレーザー光線を分割予定ライン沿って照射し、分割予定ラインに沿って機能層を除去する機能層除去工程と、
機能層が除去された分割予定ラインに沿って基板に分割加工を施してウエーハを個々のデバイスに分割するウエーハ分割工程と、を含む、
ことを特徴とするウエーハの加工方法が提供される。
上記ウエーハ分割工程における分割加工は、基板に対して吸収性を有する波長のレーザー光線を機能層が除去された分割予定ラインに沿って照射してアブレーション加工を施し、基板に分割予定ラインに沿って分割溝を形成する。
また、上記ウエーハ分割工程における分割加工は、基板に対して透過性を有する波長のレーザー光線を基板の内部に集光点を位置付けて機能層が除去された分割予定ラインに沿って照射し、基板の内部に分割予定ラインに沿って改質層を形成する。
更に、上記ウエーハ分割工程における分割加工は、機能層が除去された分割予定ラインに切削ブレードを位置付けて基板を分割予定ラインに沿って切断する。
先ず、半導体ウエーハ2を構成する基板20の裏面20bを環状のフレームに装着されたダイシングテープの表面に貼着するウエーハ支持工程を実施する。即ち、図2に示すように、環状のフレーム3の内側開口部を覆うように外周部が装着されたダイシングテープ30の表面に半導体ウエーハ2を構成する基板20の裏面20bを貼着する。従って、ダイシングテープ30の表面に貼着された半導体ウエーハ2は、機能層21の表面に被覆されたSiO2膜211が上側となる。
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が貼着されたダイシングテープ30側を載置する。そして、図示しない吸引手段を作動することにより、ダイシングテープ30を介して半導体ウエーハ2をチャックテーブル41上に保持する(ウエーハ保持工程)。従って、チャックテーブル41に保持された半導体ウエーハ2は、機能層21の表面に被覆されたSiO2膜211が上側となる。なお、図3においてはダイシングテープ30が装着された環状のフレーム3を省いて示しているが、環状のフレーム3はチャックテーブル41に配設された適宜のフレーム保持手段に保持される。このようにして、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、図示しない加工送り手段によって撮像手段43の直下に位置付けられる。
