Abstract:
1. A method comprising: providing a structure comprising a first layer overlying a substrate, where the first layer comprises a dielectric material having a plurality of pores; applying a filling material to an exposed surface of the first layer, where the filling material comprises a monomer and a photo initiator; heating the structure to a first temperature to enable the filling material to fill the plurality of pores; after filling the plurality of pores, exposing the structure to ultraviolet radiation to convert the filling material into a polymer; after exposing the structure to the ultraviolet radiation, performing at least one process on the structure; and after performing the at least one process, removing the polymer from the plurality of pores by heating the structure to a second temperature to decompose the polymer; where the filling of the plurality of pores results in the first layer having a substantially uniform composition.
