Claim Text:
1. A planarizing and/or anti-reflective composition useful in forming microelectronic structures, said planarizing and/or anti-reflective composition comprising a nonpolymeric compound, a catalyst, and a crosslinking agent dispersed or dissolved in a solvent system, said nonpolymeric compound comprising at least two epoxy moieties and at least one adamantyl group, wherein at least one of said epoxy moieties is of the formula: wherein: * is the attachment point to the compound; each y is 1-2; each R is individually —O— or —CH each R each L is individually an amino, ether, thio, hydrazine, sulfinate, sulfonate, sulfonamide, ester, carbonate, carbamate, amide, or urea linkage; each X is a chemical modification group selected from the group consisting of light attenuating moieties, solubility enhancing moieties, adhesion promoting moieties, rheology modifiers, and combinations thereof, said light attenuating moieties being selected from the group consisting of benzene, naphthalene, anthracene, C said catalyst is selected from the group consisting of sulfonic acids, photoacid generators, thermal acid generators, carboxylic acids, phosphoric acids, and mixtures thereof; and said crosslinking agent is selected from the group consisting of aminoplasts, multifunctional epoxy resins, anhydrides, vinyl ethers, and mixtures thereof.
