After the imaging, the film is baked, wherein at least one exposed region is rendered substantially soluble. After the baking, the film is developed, wherein a relief pattern remains. The relief pattern is exposed to radiation. The relief pattern is baked. The relief pattern is cured. A chemically amplified positive-tone photopatternable blend is also described. | 09-17-2009 |
20090291389 | PHOTOPATTERNABLE DIELECTRIC MATERIALS FOR BEOL APPLICATIONS AND METHODS FOR USE - A method and a composition. The composition includes at least one carbosilane-substituted silsesquioxane polymer which crosslinks in the presence of an acid. The at least one carbosilane-substituted silsesquioxane polymer is soluble in aqueous base. The method includes forming a coating on a substrate. The coating includes one or more carbosilane-substituted silsesquioxane polymers. The carbosilane-substituted silsesquioxane polymer is soluble in aqueous base. The coating is exposed to radiation, resulting in generating a latent pattern in the coating. The exposed coating is baked at a first temperature less than about 150° C. The baked coating is developed, resulting in forming a latent image from the latent pattern in the baked coating. The latent image is cured at a second temperature less than about 500° C. | 11-26-2009 |
