Abstract

An amorphous dielectric material having a dielectric constant of 10 or greater is provided herein for use in fabricating capacitors in integrated circuit applications. The amorphous dielectric material is formed using temperatures below 450° C.; therefore the BEOL metallurgy is not adversely affected. The amorphous dielectric material of the present invention exhibits good conformality and a low leakage current. Damascene devices containing the capacitor of the present invention are also disclosed.
