Abstract

A method of making a film with a high dielectric constant uses a spin-on sol-gel process to deposit the film on a substrate, the film having a composition (SiO2)x(TiO2)1−x, where 0.50<x<0.75. The resulting film is annealed in an oxygen-containing atmosphere at a temperature lying in the range of 500° C. to 700° C.
