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.

Abstract:
Filters (10, 15) suitable for microelectronic uses and the like may be prepared directly on substrates (250) either as monolithically integrated filters (10) or as hybrid filters (50) using a soluble dye material in a resin (252). The resin (252) may be applied to microelectronic substrates (250) and patterned by conventional microphotolitho-graphic processes.
Abstract:
Anti-reflective or fill composition which inhibits or blocks via or photoresist poisoning, a method of coating a substrate and curing it, and a cured protective layer derived therefrom comprises a polymer prepared from a first set of recurring monomers containing a ring member reacted with a light attenuating compound, and a second set of recurring monomers having an unreacted ring member.
