Description
ここでは噴射材は、JIS R6001の研磨微粉の粒度を有する材料である。
投射材は新東工業株式会社製アルミナ砥粒(ホワイトアランダム)WA♯240から♯600、粒径に換算すると、平均粒子径で25μmから70μmを用いた。また、噴射圧力は0.3MPaから0.5MPaを用いた。ここでは噴射材は、JIS R6001の研磨微粉の粒度を有する材料である。EPI工程後の4インチ(φ100mm)基板(ウエハ)Wの97mm×97mmの範囲での反り量は、83μmから210μmのバラツキがあったが、ブラスト処理後には40μm以下(35μmから20μm)に矯正された。なお、反り量から曲率半径を換算するといずれも30m以上であった。また、ウエハのインチサイズが今後大きくなった場合には、全体の反り量としては40μm以上となっても、φ100mmのウエハに換算した時に反り量が40μm以下であれば良い。このような反り量の範囲においては、後工程でのチップ切断時のレーザー加工での歩留まりが向上するという利点がある。
