Abstract

The material and dielectric properties of SiO2 aerogel thin films were studied. These films were fabricated by spin coating and a subsequent supercritical drying method. Film porosity was evaluated as 67% with Rutherford backscattering spectrometry and its dielectric constant was measured to be 2.15 using metal/insulator/semiconductor structure. Dielectric constant of SiO2 aerogel was sensitive to the surface coverage and we could obtain a lower dielectric constant, 2.07 with thermal dehydration at 450°C. This value was one of the lowest among intermetal dielectric materials ever reported.
