Patent ID: 8187933

Claim:
A method of forming a structure, comprising: forming a first mixed phase dielectric over a first material; the first mixed phase dielectric comprising a first homogeneous mixture of two oxides; one of said two oxides of the first homogeneous mixture having a dielectric constant of greater than or equal to 25, and the other of said two oxides of the first homogeneous mixture having a dielectric constant of less than or equal to 20; forming a single phase dielectric over and directly against the first mixed phase dielectric; the single phase dielectric consisting of a composition having a dielectric constant of greater than or equal to 25; forming a second mixed phase dielectric over and directly against the single phase dielectric; the second mixed phase dielectric comprising a second homogeneous mixture of two oxides; one of said two oxides of the second homogeneous mixture having a dielectric constant of greater than or equal to 25, and the other of said two oxides of the second homogeneous mixture having a dielectric constant of less than or equal to 20; the first and second mixed phase dielectrics being more amorphous than the single phase dielectric, and being different in composition from one another; and forming a second material over the second mixed phase dielectric.
