該エピタキシー基板の表面に該バファー層を介して積層された該光デバイス層の表面に移設基板を接合金属層を介して加熱圧着接合することによりエピタキシー基板と移設基板とからなる接合体を形成する移設基板接合工程と、
該光デバイス層の表面に接合された該移設基板を該ストリートに沿って該エピタキシー基板が露出するまで該光デバイス層とともに切断することにより、該移設基板接合工程を実施することによって該接合体に発生した反りを開放する移設基板切断工程と、
該移設基板切断工程が実施された該移設基板を保持部材に貼着し、該移設基板が接合された該光デバイス層が積層されている該エピタキシー基板の裏面側から該エピタキシー基板を透過するレーザー光線を該バファー層に集光点を位置付けて照射することにより該バファー層を分解する剥離用レーザー光線照射工程と、
該剥離用レーザー光線照射工程を実施した後に、該エピタキシー基板を該光デバイス層から剥離するエピタキシー基板剥離工程と、を含む、
ことを特徴とする光デバイスウエーハの加工方法が提供される。
また、上記移設基板切断工程は、移設基板のストリートに沿ってレーザー光線を照射することにより移設基板をストリートに沿って切断する。
図1に示す光デバイスウエーハ2は、略円板形状であるサファイア基板や炭化珪素等のエピタキシー基板20の表面20aにn型窒化ガリウム半導体層211およびp型窒化ガリウム半導体層212からなる光デバイス層21がエピタキシャル成長法によって形成されている。なお、エピタキシー基板20の表面にエピタキシャル成長法によってn型窒化ガリウム半導体層211およびp型窒化ガリウム半導体層212からなる光デバイス層21を積層する際に、エピタキシー基板20の表面20aと光デバイス層21を形成するn型窒化ガリウム半導体層211との間には窒化ガリウム(GaN)からなるバファー層22が形成される。このように構成された光デバイスウエーハ2は、図示の実施形態においてはエピタキシー基板20の厚みが例えば430μm、バファー層22を含む光デバイス層21の厚みが例えば5μmに形成されている。なお、光デバイス層21は、図1の(a)に示すように格子状に形成された複数のストリート23によって区画された複数の領域に光デバイス24が形成されている。
移設基板切断工程を実施するには、先ず上述した図5に示すようにレーザー加工装置6のチャックテーブル61上に上述した移設基板接合工程が実施され移設基板3が接合された光デバイスウエーハ2のエピタキシー基板20を載置する。従って、光デバイスウエーハ2を構成するエピタキシー基板20の表面に形成された光デバイス層21の表面21aに接合された移設基板3の裏面3bが上側となる。そして、図示しない吸引手段を作動することにより、移設基板3が接合された光デバイスウエーハ2をチャックテーブル61上に吸引保持する。このようにして、移設基板3が接合された光デバイスウエーハ2を吸引保持したチャックテーブル61は、図示しない加工送り手段によって撮像手段63の直下に位置付けられる。
