Abstract

Sol-gel derived Y₂O₃ thin films have been prepared on platinum coated silicon wafers and fired to temperatures ranging from 400°C to 750°C. Multiple coats were used to obtain films up to 0.5 μm thick with an intermediate firing of 400°C between coatings. Top Pt electrodes were sputtered to form monolithic capacitors. These films exhibited a dielectric constant of 18 and a leakage current of 10¹¹-10⁷ A/cm², making them attractive candidates for high dielectric constant dielectric films in high density DRAMs.
