Patent number: 6893684Abstract: 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.Type: GrantFiled: December 3, 2002Date of Patent: May 17, 2005Assignee: Brewer Science Inc.Inventors: Rama Puligadda, James E. Lamb, III, Tony D. Flaim
