Description
本願は、2007年4月10日出願、米国仮特許出願番号第60/911,049号(特許文献1)の便益を主張する。
著作権(c)2008 Ledalite Architectural Products, Inc.社。本特許文献の開示の一部は、著作権保護の対象となるマテリアルを含む。著作権所有者は、特許商標局の特許ファイル又は記録にある通り、特許情報開示又は特許文献の何人による複製に意義を問わないが、それ以外の全ての著作権権利を留保する。37 CFR § 1.71(d)。
露出間の感光性板の運動及び露出の数の多種の組合せは、図6A,6B,6C,及び6Dにおいて示される通り、均一且つ環状のビーム分布を有するキノフォームディフューザーの製造に寄与する。ガウス分布とは異なり、かかるビーム分布は、特定の角度領域の外側における大幅に低減された散乱を呈する。露出間における感光性板の運動はまた、ゼロ次ビームの排除、及び色消し照射下におけるスペクトル分散の不在を呈するキノフォームディフューザーの製造を可能にする。
γ=1/(log10(Emax/Emin)) (3)
と表わされる。式中、Eminは、エッチングをもたらす光能動的構成要素における光化学反応を作るよう要求される最小光線性露出(actinic exposure)(1平方センチメートル当たりのミリジュールで測定される)であり、Emaxは、下方にある基板に対するフォトレジストのエッチングをもたらすよう要求される最大光線性露出である。
78(2):249−251(2001年1月8日)において記載される通りである。上述の通り、例えば、Galajda及びOrmosの文献において、Norland Products社(米国ニュージャージー州Cranbury在)からのNorland NOA 63光学接着剤の層は、基板に対して適用される。続いて、20ミリワットのアルゴンレーザの514nmライン出力は、二光子重合を開始するよう前出の層内において0.5マイム直径スポットに対して集束される。基板をLinos Photonics(米国マサチューセッツ州ミルフォード在)からのP3D 20−100 三軸圧電性平行移動段階を有する事前にプログラムされた軌道に沿って基板を動かすことは、任意の三次元マイクロ構造が作られるようにする。続いて露出されない樹脂は、アセトンにおいて溶解することによって除去される。
