Abstract
Description
更に、図5に示されるように、エッジ部材を用いた剥離を行ったとしても、剥離用テープを引っ張って接着シートの剥離を行うと、剥離用テープの剥離方向に沿う延長線上は張力が伝わってエッジ剥離が実現できるが、エッジ部材の先端側に位置するその他の接着シート部分は、当該接着シートが延びることに起因した剥離遅れEを発生する。この剥離遅れEが生じると、接着シートの折り曲げ縁をエッジ部材に密着させるこができなくなり、エッジ部材での剥離効果が十分に得られない、という不都合を招来する。
本発明は、このような不都合に着目して案出されたものであり、その目的は、接着シートの剥離抵抗を増大させることなく、ウエハの浮き上がりを防止して接着シートのスムースなる剥離を行うことのできるシート剥離装置及び剥離方法を提供することにある。
また、本発明の他の目的は、接着シートを剥離する際に形成される折り曲げ縁を所定部材に密着させた状態を維持して当該接着シートを剥離することのできるシート剥離装置及び剥離方法を提供することにある。
また、先尖部を備えたエッジ部材を採用することで、剥離角度(図4(D)のθで示す角度)を大きくすることができ、被着体の浮き上がりをより効果的に防止して剥離することができる。
更に、挟込手段として、ローラや、複数のローラに巻装された挟込用エンドレス部材を用いることで、当該挟込手段と剥離補助手段との間における抵抗を極小化して接着シートを通過させることができる。
また、エンドレス部材の内周側にプラテンを配置した場合には、エンドレス部材の回行軌跡を一定位置に保つことができる。
