Webフォトレジスト （ 英語 ：photoresist）とは、 フォトリソグラフィ において使用される、光や電子線等によって溶解性などの物性が変化する組成物である。 物質の表面に塗布され、後に続くエッチングなどの処理から物質表面を保護することから、「レジスト」 (resist) の名がある。 しかしながら、現在では、感光性を有し、画像様露光・現像によりパ … WebThe photolithographic process was as following. The black photoresist was spin coated on the wafer (Si/SiO 2 200 nm) with a stepwise speed of 300 rpm/5 sec, 500 rpm/5 sec, and 5000 rpm/50 sec. After soft bake at 120˚C for 100 sec, the dry black photoresist thin film was exposed to UV irradiation (120 mJ/cm 2) through the photomask
