  • Patent number: 6936659
    Abstract: Polymer-bonded functional agents are each obtained by reacting a functional agent containing reactive groups with a polymer containing groups reactive with the reactive groups of the functional agent. The functional agent comprises at least one functional agent selected from the group consisting of antioxidants, ultraviolet absorbers, light stabilizers, infrared absorbers and antistatic agents. Use of these polymer-bonded functional agents can provide articles with improved functions.

  • Patent number: 6893684
    Abstract: Anti-reflective compositions and methods of using those compositions with low dielectric constant materials are provided. In one embodiment, the compositions include polymers comprising recurring monomers having unreacted ring members. In another embodiment, the polymers further comprise recurring monomers comprising ring members reacted with a light attenuating compound so as to open the ring. The compositions can be applied to dielectric layers so as to minimize or prevent reflection during the dual damascene process while simultaneously blocking via or photoresist poisoning which commonly occurs when organic anti-reflective coatings are applied to low dielectric constant layers.
