Abstract
Embodiments in accordance with the present invention encompass polymers having at least one norbornene-type repeating unit derived from a norbornene-type monomer having a polyhedral oligosilsesquioxane pendant group. Such polymers, are formed by addition polymerizations that employ one of a neutral or cationic palladium catalyst or a neutral nickel catalyst. Such polymers are useful for a variety of applications such as a positive tone or negative tone photodefinable material, a low-k dielectric constant material, an etch selective layer, a sacrificial material or the like. In addition, embodiments of the present invention include devices formed using such polymers.
