Description
ウエーハ配設工程を実施するに際し、まず、後述する熱圧着工程を実施する熱圧着装置30(図2(a)を参照。)の保持手段となる支持テーブル20の上面22の中央にシート14を敷設する。支持テーブル20の上面22は、フッ素樹脂で被覆されており、且つ平坦に形成されている。さらに、図2(a)に示すように、支持テーブル20の内部には、加熱手段としての温度センサ(図示は省略)を含む電気ヒータ24が内蔵されている。
上記したウエーハ配設工程が完了したならば、次いでシート熱圧着工程を実施する。シート熱圧着工程は、シート14及び剥離層16を介して支持テーブル20上に配設されたウエーハ10を密閉環境内で減圧してシート14を加熱すると共に、ウエーハ10を押圧して、ウエーハ10の外周をシート14に熱圧着する工程である。図2を参照しながら、該シート熱圧着工程を実施する熱圧着装置30の機能、作用について説明する。
上記した熱圧着工程が完了し、一体化ウエーハWが形成されたならば、ウエーハ10の裏面を加工する加工工程を実施する。本実施形態の加工工程は、裏面10bを研削する研削加工を実施するものであり、図3、図4を参照しながらより具体的に説明する。
支持テーブル20から一体化ウエーハWを搬出したならば、図5(a)に示す剥離工程を実施するための保持手段70に搬送する。保持手段70の上面は上記したチャックテーブル52と同様に、通気性を有する吸着チャック72によって形成されており、図示しない吸引手段が接続されている。
