Description
図1〜図6は第1実施形態を示すもので、以下、第1の基板として、裏面研削およびTSV(through silicon via)を形成する工程を実施する半導体基板1を対象とし、その加工工程について説明する。
図7〜図12は第2実施形態を示している。以下、第1実施形態と異なる部分について、説明する。
支持基板4の剥離時に有効エリア外のチップPは割れるが、有効エリアのチップPに及ぶ割れの進展を確実に防ぐこと出来る。
図13は第3実施形態を示すもので、第1実施形態で用いた紫外線照射装置の異なる例を示している。紫外線照射装置20は、紫外線照射装置10と同様に、半導体基板1の素子形成部2側を支持基板4に貼り付けた状態でテープ6を素子形成部2の裏面側に貼り付け、これをリングフレーム7により保持した状態のものに、紫外線を照射する装置である。
上記実施形態で説明したもの以外に次のような変形形態に適用することができる。
第1の基板および第2の基板は、半導体基板1および支持基板4を用いる場合で説明したが、これに限らず、接着層で貼り合わせた状態の2枚の基板を分離する構成であれば適用できる。
