  • Thermosetting anti-reflective coatings for full-fill dual damascene process
    Patent number: 6444320
    Abstract: New polymers and anti-reflective or fill compositions including those polymers are provided. The polymer comprises recurring monomers according to the formula wherein R comprises a light attenuating compound. The inventive compositions can be used to protect contact or via holes from degradation during subsequent etching in the dual damascene process.

  • Method of manufacturing microelectronic devices having multifunctional photolithographic layers
    Patent number: 5401613
    Abstract: A photolithographic composition having improved processability and which eliminates the need for interlayering multiple special purpose coatings in the production of microelectronic devices is surprisingly made possible by selective dissolution of a polymer and an effective light attenuating material in critical solvents. The polymers which are used in the present invention include homopolymers and copolymers of poly(vinylpyridine).
