- インゴットの端面からインゴットに対して透過性を有する波長のレーザー光線の集光点を生成すべきウエーハの厚みに相当する深さに位置づけてレーザー光線を照射し剥離層を形成したインゴットから生成すべきウエーハを剥離する剥離装置であって、
インゴットを保持する保持手段と、
該保持手段に保持されたインゴットに超音波を付与して該剥離層を刺激する超音波手段と、
生成すべきウエーハを吸引保持する保持部と該保持部から突出して生成すべきウエーハの外周を囲繞するリング壁とを備えた剥離手段と、
から少なくとも構成され、
該リング壁の内側には、インゴットから剥離されたウエーハの剥離面に向かって洗浄水を噴射して洗浄する噴射口が複数形成されている剥離装置。 - 該噴射口から噴射され該保持部に保持されたウエーハの剥離面を洗浄した洗浄水は中央部で合流して垂下し、該保持部に保持されたウエーハの直下に位置するインゴットの剥離面を洗浄する請求項1記載の剥離装置。
- インゴットは、c軸とc軸に対し直交するc面とを有する単結晶SiCインゴットであり、
該剥離層は、単結晶SiCに対して透過性を有する波長のレーザー光線の集光点を単結晶SiCインゴットの端面から生成すべきウエーハの厚みに相当する深さに位置づけて単結晶SiCインゴットにレーザー光線を照射してSiCがSiとCとに分離した改質部と改質部からc面に等方的に形成されるクラックとからなる請求項1記載の剥離装置。 - インゴットは、端面の垂線に対してc軸が傾きc面と端面とでオフ角が形成されている単結晶SiCインゴットであり、
該剥離層は、オフ角が形成される方向と直交する方向に改質部を連続的に形成して改質部からc面に等方的にクラックを生成し、オフ角が形成される方向にクラックの幅を超えない範囲で単結晶SiCインゴットと集光点とを相対的にインデックス送りしてオフ角が形成される方向と直交する方向に改質部を連続的に形成して改質部からc面に等方的にクラックを順次生成した剥離層である請求項3記載の剥離装置。
