Abstract

Low dielectric constant, nanoporous hydrogen silsesquioxane (HSQ) films were prepared using hybrid templating method by addition of a sacrificial labile polymer, polybutadiene (PB). Thermal gravimetric analyzer (TGA) was employed to monitor the decomposition behavior of HSQ-PB films. Curing of HSQ and decomposition of PB were performed by a two-stage thermal treatment to obtain a defect-free film. The porosity level and pore morphology of the resultant porous films were found to be dependent upon thermal treatment conditions applied.
