Mesoporous Low Dielectric Poly(silsesquioxane) Thin Films Templated by Various Surfactants
Published online by Cambridge University Press: 01 February 2011
Abstract
Mesoporous low dielectric poly(silsesquioxane) thin films have been fabricated by templating various surfactants such as cetyltrimethyl ammonium bromide (CTAB) or 4-octylphenol polyethoxylate (OPE) in the silsesquioxane polymer matrix and their properties of the thin films characterized by electrical, mechanical and structural characterization. Depending on the types of the surfactants, mesoporous poly(silsesquioxane) thin films with different porosities have been formed. The dielectric constant (k) of the films depended on the content or porosity of the surfactants. The dielectric constants of ca. 2.2–2.4 were obtained for the films with relative porosities of about 15–30 vol. % to the polymer matrix itself. The elastic modulus of the films showed a dependency on the type, content of the surfactants and was ca. 2.9 GPa with the k value of ca. 2.38.
