    摘要: A photosensitive formulation for high-temperature-resistant photoresists is based on polyhydroxyamides. The photosensitive formulations display a much higher photosensitivity than the comparable formulations based on quinone azide photoactive components. After conversion to the polybenzoxazole, the novel formulations also display a lower dielectric constant than the quinone azide-based formulations. A film can be made by applying the photosensitive formulation to a wafer and then evaporating the solvent. A method for fabricating electronics and micorelectronics structures a wafer by using the film in photolithography.
