Description
基板の距離を離すことで、前記基板を剥離する剥離工程とを備える。
図1〜図22は、第一の実施形態の半導体装置の製造装置及び製造方法を説明する図である。
図15及び図16は、第一のテープ80が剥離された状態を示した模式的な図である。
本実施形態によれば、少なくとも第一のテープ80の少なくとも剥離箇所を冷却しているステージが−15度から5度又は10度の範囲に冷却されている状態で、基板20は剥離される。特にステージが5度以下に冷却されている状態であれば、なお望ましい。第一のテープ80が冷却されていることで、容易に基板20を剥離することが可能である。
第二の実施形態は、第一の実施形態と第一のテープの弾性率の上昇のさせ方が異なる。すなわち、第二の実施形態では、第一のテープ80に紫外線(光)を当てることで、弾性率を大きくする。
