該樹脂フィルムの該上面に供給された該液状樹脂を該カバーフィルムで覆い、該カバーフィルムを介して平坦な押圧面で該液状樹脂を押圧し、該液状樹脂を該樹脂フィルム上に押し広げる押圧ステップと、
該押圧ステップで該樹脂フィルム上に押し広げられた該液状樹脂を硬化させ、該樹脂フィルムと、硬化した該液状樹脂と、該カバーフィルムと、を含む該保護部材を該基板の該表面に形成する硬化ステップと、を備え、
該第1の搬送ステップでは、該基板支持部上において、該基板と重ならない領域において該樹脂フィルムを該吸引パッドで吸引保持するとともに該基板と重なる領域において該非接触式吸引パッドで該樹脂フィルムを吸引保持し、その後、該移動機構を作動させて該樹脂フィルムが密着した該基板を該支持テーブル上に搬送し、該吸引パッドによる該樹脂フィルムの吸引保持を解除し、その後に該非接触式吸引パッドによる該樹脂フィルムの吸引保持を解除することを特徴とする保護部材形成方法。 - 請求項5に記載の保護部材形成装置を使用して該表面に該凹凸を備える該基板の該表面に該保護部材を形成する保護部材形成方法であって、
該樹脂フィルムで該基板の該表面を覆い、該樹脂フィルムを該基板の該表面の該凹凸に倣うように該基板に密着させる樹脂フィルム密着ステップと、
該基板に密着した該樹脂フィルムの該上面の該基板と重なる領域に、硬化可能な該液状樹脂を供給する液状樹脂供給ステップと、
該樹脂フィルムの該上面に供給された該液状樹脂を該カバーフィルムで覆い、該カバーフィルムを介して平坦な押圧面で該液状樹脂を押圧し、該液状樹脂を該樹脂フィルム上に押し広げる押圧ステップと、
該支持テーブル上で、該押圧ステップで該樹脂フィルム上に押し広げられた該液状樹脂を硬化させ、該樹脂フィルムと、硬化した該液状樹脂と、該カバーフィルムと、を含む該保護部材を該基板の該表面に形成する硬化ステップと、
該表面に該保護部材が形成された該基板を該支持テーブルから該切断ユニットの該テーブルに該搬送ユニットを使用して搬送する第2の搬送ステップと、
該切断ユニットにおいて、該保護部材を該基板の外周に沿って切断する外周余剰部切断ステップと、を備え、
該第2の搬送ステップでは、該支持テーブル上において、該基板と重ならない領域において該樹脂フィルムを該吸引パッドで吸引保持するとともに該基板と重なる領域において該非接触式吸引パッドで該カバーフィルムを吸引保持し、その後、該移動機構を作動させて該表面に該保護部材が形成された該基板を該切断ユニットの該テーブル上に搬送し、該吸引パッドによる該樹脂フィルムの吸引保持を解除し、その後に該非接触式吸引パッドによる該カバーフィルムの吸引保持を解除することを特徴とする保護部材形成方法。
