Abstract:
1. A smoothing layer for use with a thick film dielectric layer, the smoothing layer comprising a high dielectric constant material with an areal density of pit defects of about less than 100 defects per square millimeter, made by the addition of a surfactant to a metal organic solution or a sol gel of organo metallic precursor compounds that is subsequently sintered on said thick film dielectric layer, wherein said surfactant is selected from the group consisting of a non-ionic surfactant selected from the group consisting of dimethyl hexynol, ethoxylated acetylenic diols, p-tertiary octylphenoxy polyethyl alcohol and mixtures thereof and an anionic surfactant selected from the group consisting of alkyl ether phosphate, cetyltrimethylammonium bromide and mixtures thereof.
