WebThe high-resolution resist AZ® 701 MIR 14cps or 29cps, are optimized for both requirements and reveal a softening point of 130°C. Thick resists: If resist film thicknesses exceeding 5 µm are required, the thick positive resists AZ® 4562 or AZ® 9260, or the negative AZ® 15nXT or AZ® 125nXT are recommended. The two nXT resists cross-link ... WebA photoresist typically contains a photoactive compound (PAC) and an alkaline-soluble resin. The PAC, mixed into the resin, renders it insoluble. This mixture is coated onto the …

Webexposed photoresists as a function of the photo active compound concentration. Before exposure, the inhibitor DNQ-sulfonate decreases the devel-opment rate by 1-2 orders of magnitude, which is similar to the development rate increase caused by the product of the photoreaction, the indene carboxylic acid. The fig. right-hand, bottom shows the ... WebThe Photo Initiator (Photo active Compound: PAC) The photo active compound of AZ® and TI photoresists belongs to the group of diazonaphtho-quinones (DNQ). Their presence in photoresists reduces - as compared with pure Novolak resin - the alkaline solubility by more than one order of magnitude. During exposure with UV-light (typically < 440 nm) the
Web-bubbles originate from the gradual decomposition of the photo active compound in the liquid resist. If - after storage for a certain time - the resist bottle is opened, the N 2 dissolved in the resist may form bubbles. In case of either air or N 2 bubbles, a delay before dispensing of - dependant on the resist Webtoo long or/and hot, a significant amount of the photo active compound will be thermally decomposed which lowers the development rate. For thin resist films around 1 µm, we rec-ommend a softbake at 100-110°C for 1 minute on a hotplate. Detailed information on softbaking can be found in the document Softbake of Photoresists.
