    摘要: Novel methods of double patterning a photosensitive resin composition are provided. The methods involve applying the photosensitive composition to a substrate and thermally crosslinking the composition. The crosslinked layer can be used to provide reflection control. Upon exposure to light, the crosslinked polymer (or oligomer or monomer) in the compositions will decrosslink, rendering the light-exposed portions soluble in typical photoresist developing solutions (e.g., alkaline developers). Advantageously, the crosslinked portions of the composition remain insoluble in the solvent used to form the photosensitive composition. As a result, the coating, lithographic, and or developing steps can be repeated multiple times in varying order, depending upon the particular process, without destroying earlier-formed patterns.

    摘要: Novel, developer-soluble anti-reflective coating compositions and methods of using those compositions are provided. The compositions comprise a multi-functional acid reacted with a multi-functional vinyl ether to form a branched polymer or oligomer. In use, the compositions are applied to a substrate and thermally crosslinked. Upon exposure to light and post-exposure baking, the cured polymers/oligomers will decrosslink and depolymerize, rendering the layer soluble in typical photoresist developing solutions (e.g., alkaline developers).

    摘要: Novel double- and triple-patterning methods are provided. The methods involve applying a shrinkable composition to a patterned template structure (e.g., a structure having lines) and heating the composition. The shrinkable composition is selected to possess properties that will cause it to shrink during heating, thus forming a conformal layer over the patterned template structure. The layer is then etched to leave behind pre-spacer structures, which comprise the features from the pattern with remnants of the shrinkable composition adjacent the feature sidewalls. The features are removed, leaving behind a doubled pattern. In an alternative embodiment, an extra etch step can be carried out prior to formation of the features on the template structure, thus allowing the pattern to be tripled rather than doubled.

    摘要: The present invention provides methods of fabricating microelectronics structures and the resulting structures formed thereby using a dual-layer, light-sensitive, wet-developable bottom anti-reflective coating stack to reduce reflectance from the substrate during exposure. The invention provides dye-filled and dye-attached compositions for use in the anti-reflective coatings. The anti-reflective coatings are thermally crosslinkable and photochemically decrosslinkable. The bottom anti-reflective coating stack has gradient optical properties and develops at the same time as the photoresist. The method and structure are particularly suited to high-NA lithography processes.

    摘要: An improved method for applying organic antireflective coatings to substrate surfaces and the resulting precursor structures are provided. Broadly, the methods comprise chemical vapor depositing (CVD) an antireflective compound on the substrate surface. In one embodiment, the compound is highly strained (e.g., having a strain energy of at least about 10 kcal/mol) and comprises two cyclic moieties joined to one another via a linkage group. The most preferred monomers are [2.2](1,4)-naphthalenophane and [2.2](9,10)-anthracenophane. The CVD processes comprise heating the antireflective compound so as to vaporize it, and then pyrolizing the vaporized compound to form stable diradicals which are subsequently polymerized on a substrate surface in a deposition chamber. The inventive methods are useful for providing highly conformal antireflective coatings on large substrate surfaces having super submicron (0.25 μm or smaller) features.
