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

WebPhotoactive compound rich, highly diluted resists often show a accelerated ageing, sometimes accompanied by particle formation in the resist. Therefore, for resist film thicknesses < 500 nm, we recommend the AZ ® ECI 3007 for maximum adhesion or thermally stable high resolution AZ ® 701 MiR.
Webposes a significant part of the photo active compound DNQ thus reducing the development rate and increasing the dark erosion at the same time (unexposed DNQ is a development in-hibitor). Additionally, a short flood exposure will cause an offset in the development rate. A high developer concentration (e. g.
