    摘要: A process for making an element for forming a final image with an overall attribute by exposure to actinic radiation, the process comprising: providing a support element having a surface; applying a first layer having a first surface and a second surface to the surface of the support element, the first surface of the first layer being adjacent to the surface of the support element and the second surface of the first layer being opposite the first surface; applying, prior to image-wise exposure to actinic radiation, a second layer adjacent to the second surface of the first layer, the second layer having an inner surface and an outer surface, the first layer comprising a photosensitive composition and a feature which imparts a dominant attribute to the first layer, the feature being selected from the group consisting of a fluorescent feature, a metallic feature, an opacity enriching feature or a combination of at least two of the foregoing features, the second layer comprising a first colorant; wherein the overall attribute of the final image is defined by the dominant attribute of the first layer. The invention also relates to an element for forming a final image having a dominant attribute.

    摘要: The invention relates to a multilayer microstructure and a method for preparing thereof. The method involves first applying a first photodefinable composition having a first exposure wavelength on a substrate to form a first polymeric layer. A portion of the first photodefinable composition is then exposed to electromagnetic radiation of the first exposure wavelength to form a first pattern in the first polymeric layer. After exposing the first polymeric layer, a second photodefinable composition having a second exposure wavelength is applied on the first polymeric layer to form a second polymeric layer. A portion of the second photodefinable composition is then exposed to electromagnetic radiation of the second exposure wavelength to form a second pattern in the second polymeric layer. In addition, a portion of each layer is removed according to the patterns to form a multilayer microstructure having a cavity having a shape that corresponds to the portions removed.

    摘要: A first embodiment of the present invention pertains to a method of patterning a semiconductor device conductive feature while permitting easy removal of any residual masking layer which remains after completion of the etching process. A multi-layered masking structure is used which includes a layer of high-temperature organic-based masking material overlaid by either a patterned layer of inorganic masking material or by a layer of patterned high-temperature imageable organic masking material. The inorganic masking material is used to transfer a pattern to the high-temperature organic-based masking material and is then removed. The high-temperature organic-based masking material is used to transfer the pattern and then may be removed if desired. This method is also useful in the pattern etching of aluminum, even though aluminum can be etched at lower temperatures. A second embodiment of the present invention pertains to a specialized etch chemistry useful in the patterning of organic polymeric layers such as low k dielectrics, or other organic polymeric interfacial layers. This etch chemistry is useful for mask opening during the etch of a conductive layer or is useful in etching damascene structures where a metal fill layer is applied over the surface of a patterned organic-based dielectric layer. The etch chemistry provides for the use of etchant plasma species which minimize oxygen, fluorine, chlorine, and bromine content.
