    Abstract: Acid-sensitive, developer-soluble bottom anti-reflective coating compositions are provided, along with methods of using such compositions and microelectronic structures formed thereof. The compositions preferably comprise a crosslinkable polymer dissolved or dispersed in a solvent system. The polymer preferably comprises recurring monomeric units having adamantyl groups. The compositions also preferably comprise a crosslinker, such as a vinyl ether crosslinking agent, dispersed or dissolved in the solvent system with the polymer. In some embodiments, the composition can also comprise a photoacid generator (PAG) and/or a quencher. The bottom anti-reflective coating compositions are thermally crosslinkable, but can be decrosslinked in the presence of an acid to be rendered developer soluble.

    Abstract: 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).

    Abstract: Novel compositions and methods of using those compositions to form high refractive index coatings are provided. The compositions preferably comprise both a reactive solvent and a high refractive index compound. Preferred reactive solvents include aromatic resins that are functionalized with one or more reactive groups (e.g., epoxides, vinyl ethers, oxetane), while preferred high refractive index compounds include aromatic epoxides, vinyl ethers, oxetanes, phenols, and thiols. An acid or crosslinking catalyst is preferably also included. The inventive compositions are stable under ambient conditions and can be applied to a substrate to form a layer and cured via light and/or heat application. The cured layers have high refractive indices and light transmissions.
