  • Patent number: 6730454
    Abstract: Antireflective compositions characterized by the presence of an SiO-containing polymer having chromophore moieties and transparent moieties are useful antireflective hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions of the invention are advantageously useful with shorter wavelength lithographic processes and/or have minimal residual acid content.

  • Publication number: 20040045866
    Abstract: The present invention includes a packaged coated workpiece. The packaged coated workpiece has: (1) a workpiece coated with a resist film sensitive to optical radiation, particulates or chemical contaminants; (2) an inner barrier sealed to enclose the coated workpiece and optionally a first getter agent, to produce a sealed first enclosure; and (3) an outer barrier sealed to enclose the sealed first enclosure and optionally a second getter agent, provided that the packaged coated workpiece has at least one getter agent, to produce a packaged coated workpiece suitable for storage for a period of at least one week without substantial loss of sensitivity, resolution or performance. The present invention also includes a process for preparing a packaged coated workpiece and a method of increasing the storage time of a coated workpiece to at least one week without substantial loss of sensitivity, resolution or performance.

  • Patent number: 6641971
    Abstract: A chemically amplified resist composition comprises an aqueous base soluble polymer or copolymer having one or more polar functional groups, wherein at least one of the functional groups is protected with a cycloaliphatic silyl ketal group but may also include other protecting groups as well as unprotected acidic functionalities. A ratio of protected to unprotected acidic functionalities is preferably selected to most effectively modulate a solubility of the resist composition in an aqueous base or other developer. The resist composition further comprises an acid generator, preferably a photoacid generator (PAG), and a casting solvent, and may also include other components, such as, a base additive and/or surfactant.
