    摘要: An integrated circuit capacitor is formed by first forming a first dielectric layer (25) over a semiconductor (10). A copper structure (35) is formed in the first dielectric layer (25) and a second dielectric layer (80) is formed over the copper structure (35). A metal containing layer (90) is formed over the second dielectric layer (80) and the copper structure (35) and a planar surface is formed by removing portions of the metal containing layer (90) and the second dielectric layer (80). The second dielectric layer (80) can comprise a high-k dielectric material. The metal containing layer can comprise two metal layers.
