Abstract: PROBLEM TO BE SOLVED: To provide an anti-reflective composition and a method of using the composition to form a circuit. SOLUTION: The composition comprises a polymer dissolved or dispersed in a solvent system. The polymer of the composition is generated by reacting an organic compound with a polymeric metal alkoxide, and the polymeric metal alkoxide includes a recurring unit having formula (I), wherein M is a metal individually selected from a group composed of titanium, zirconium, silicon and aluminum, each L is individually selected from a group consisting of diketo and alkoxide ligands, and the organic compound includes a functional group for coordinating with M of the polymeric metal alkoxide.

Abstract: Anti-reflective compositions and methods of using these compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. In a preferred embodiment, the polymers include a light-attenuating moiety having a structure selected from the group consisting of:where:each of X and Y is individually selected from the group consisting of electron withdrawing groups;R is selected from the group consisting of alkyls and aryls; andR is selected from the group consisting of hydrogen and alkyls.The resulting compositions are spin bowl compatible (i.e., they do not crosslink prior to the bake stages of the microlithographic processes or during storage at room temperature), are wet developable, and have superior optical properties.

Abstract: Novel anti-reflective coatings comprising small molecules (e.g., less than about 5,000 g/mole) in lieu of high molecular weight polymers and methods of using those coatings are provided. In one embodiment, aromatic carboxylic acids are used as the chromophores, and the resulting compounds are blended with a crosslinking agent and an acid. Anti-reflective coating films prepared according to the invention exhibit improved properties compared to high molecular weight polymeric anti-reflective coating films. The small molecule anti-reflective coatings have high etch rates and good via fill properties. Photolithographic processes carried out with the inventive material result in freestanding, 110-nm profiles.

Abstract: Anti-reflective compositions and methods of using these compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. In a preferred embodiment, the polymers of the composition include recurring monomers having the formulas where: (1) each R is individually selected from the group consisting of hydrogen, —OH, aliphatics, and phenyls; and (2) L is selected from the group consisting of —SO2— and —CR′2—, where each R′ is individually selected from the group consisting of hydrogen, aliphatics, phenyls, and —CX3, where each X is individually selected from the group consisting of the halogens. The resulting compositions are spin bowl compatible (i.e., they do not crosslink prior to the bake stages of the microlithographic processes or during storage at room temperature), are wet developable, and have superior optical properties.

Abstract: This invention describes compositions and methods of using non-covalently crosslinked resin coatings for lithographic applications. These materials are designed to undergo, after coating, a change that provides solvent resistance and, with some materials, simultaneous aqueous-base solubility. Non-covalent interactions allow for easier removal of these coatings than of covalcntly crosslinked materials. These types of materials are well-suited for trench and gap fill applications, as well as for anti-reflective coatings, spin-on carbon layers, and etch masks.
