Abstract: A method of fabricating an MIM capacitor may include a first electrode formed on and/or over a semiconductor substrate, a dielectric layer composed of an oxygen material formed on and/or over the first electrode under an oxygen atmosphere. A second electrode is formed on and/or over the dielectric layer. Because the dielectric layer is formed under an oxygen atmosphere, an oxygen composition ratio of the dielectric layer is increased.
