Description
本出願は、2014年2月25日に出願された“Chemical Amplification Methods and Techniques for Developable Bottom Anti−reflective Coatings and Dyed Implant Resists”という名称の米国仮特許出願第61/944,394号明細書の利益を主張し、その全体が参照により本明細書に援用される。
1)ポリアミド酸(polyamic acid)誘導体などの等方性現像を示す非感光性(non-photosensitive)現像液可溶性系。
2)メタクリル酸ベンジル(BMA)およびメバロン酸(mevalonic)ラクトンメタクリレート(MLMA)などの溶解性を得る(develop)ための感光性開裂反応を開始する感光性DBARC、またはヒドロキシル含有ポリマーを有するビニロジー(vinylozy)材料などの可溶性を得る(develop)ための架橋/脱架橋反応を開始する感光性DBARC。
3)光酸発生剤なし(PAGなし)のDBARCにおけるフォトレジスト誘導現像挙動。この第3の方法において、DBARCは、本来感光性ではなく、現像のための露光したフォトレジストからの光酸の拡散に依存する。あるいは、酸増幅技術をフォトレジストに適用することもでき、特許請求の範囲はDBARC用途に限定されるものではない。
206 前記下層上にフォトレジスト層を堆積するステップであって、フォトレジストが、第1の光波長活性化閾値と第1の光波長活性化閾値とを含む、ステップ
208 パターン化マスクを通して第1の光波長を前記基板上に露光するステップ
210 第2の光波長を前記基板上に露光するステップ
212 前記基板上の前記フォトレジスト層を現像するステップ
304 下層(underlying layer)と、反射防止コーティング(ARC)層と、フォトレジスト層と、を含む基板を受け取るステップ
306 パターン化マスクを通して第1の光波長を前記基板上に露光するステップ(FIG.3Bのブロック308に続く)
308 (FIG.3Aのブロック306からの続き)第2の光波長を前記基板上に露光するステップ
310 前記フォトレジスト層と前記ARC層とを現像するステップ
