Interpolymerized With Monomer Of Diverse Carboxylic Ester Patents (Class 526/325)
  • Patent number: 6548613
    Abstract: The present invention provides a polymer that can be used as an anti-refelctive coating (ARC) polymer, an ARC composition comprising the same, methods for producing the same, and methods for using the same. The polymer of the present invention is particularly useful in a submicrolithographic process, for example, using KrF (248 nm), ArF (193 nm), or F2 (157 nm) laser as a light source. The polymer of the present invention comprises a chromophore that is capable of absorbing light at the wavelengths used in a submicrolithographic process. Thus, the ARC of the present invention significantly reduces or prevents back reflection of light and the problem of the CD alteration caused by the diffracted and/or reflected light. The ARC of the present invention also significantly reduces or eliminates the standing wave effect and reflective notching.
