HIGH ASPECT RATIO, FLEXIBLE THICK FILM POSITIVE PHOTORESIST Abstract of the Disclosure A crack resistant thick film positive photoresist having a thickness of from greater than 5µ to 100µ is coated as a single layer on a substrate to provide a relief structure thereon having vias in which the sidewalls are substantially vertical. The photoresist composition comprises a novolac resin, a photosensitizer, and a copolymer of an alkyl vinyl ether and an unsaturated dicarboxylic acid, ester or anhydride thereof. |
