Summary:To provide an expanding device which can reduce a risk that a holding table may be heated and can also reduce a risk that a sheet may be lifted from the holding table, while reducing a risk that foreign objects generated when heating the sheet may be adhered to a workpiece.SOLUTION: An expanding device 1 has: a frame fixing part 20 which fixes an annular frame 211 of a workpiece unit 200; a holding table 30 which holds a workpiece 201; an expanding unit 40 which expands a sheet 210; a heating unit 50 which heats the sheet 210 between an outer peripheral side of the workpiece 201 and an inner peripheral edge of the annular frame 211; and a cover 60 which covers the workpiece 201 held by the holding table 30. The cover 60 covers the workpiece 201 when the sheet 210 is heated by the heating unit 50.SELECTED DRAWING: Figure 2 【課題】シートを加熱することで発生する異物が被加工物に付着してしまう恐れを抑制しつつ、保持テーブルが加熱されてしまう恐れを抑制し、なおかつ、シートが保持テーブルから浮いてしまうおそれを抑制できるエキスパンド装置を提供すること。【解決手段】エキスパンド装置1は、被加工物ユニット200の環状フレーム211を固定するフレーム固定部20と、被加工物201を保持する保持テーブル30と、シート210を拡張する拡張ユニット40と、被加工物201の外周側と環状フレーム211の内周縁との間のシート210を加熱する加熱ユニット50と、保持テーブル30に保持された被加工物201を覆うカバー60と、を有する。カバー60は、シート210が加熱ユニット50によって加熱される際に、被加工物201を覆う。【選択図】図2
