WebThe Photo Reaction Positive and Image Reversal Resists The photo active compound of AZ® and TI photoresists belongs to the group of diazonaphtho-quinone-sulphonates (DNQ). Their presence in photoresists reduces the al-kaline solubility by more than one order of magnitude (Meyerhofer-plot right-hand). During exposure, the DNQ transforms into a WebNov 15, 2024 · 正性光刻胶。树脂是一种叫做线性酚醛树脂的酚醛甲醛，提供光刻胶的粘附性、化学抗蚀性，当没有溶解抑制剂存在时，线性酚醛树脂会溶解在显影液中；感光剂是光敏化合物（PAC，Photo Active Compound），最常见的是重氮萘醌（DNQ），在曝光前，DNQ 是一种强烈的溶解抑制剂，降低树脂的溶解速度。
