摘要:A capacitor and method of making is described incorporating a semiconductor

substrate, a bottom electrode formed on or in the substrate, a dielectric layer of barium

or lead silicate, and a top electrode. A sandwich dielectric of a barium or lead silicate and

a high dielectric constant material such as barium or lead titanate may form the dielectric.

The silicate layer may be formed by evaporating and diffusing, ion implanting, or

electroplating and diffusing barium or lead. The high epsilon dielectric constant material

may be formed by sol gel deposition, metal organic chemical vapor deposition or

sputtering. The invention overcomes the problem of a bottom electrode and dielectric

layer which chemically interact to form a silicon oxide layer in series or below the desired

dielectric layer.
