Capacitor with multiple-component dielectric and method of fabricating same |
摘要 |
A capacitor has a pair of plates separated by a capacitor dielectric material which is formed of multiple separate layers of different dielectric materials having different electrical characteristics. The different electrical characteristics are represented by linearity curves that curve relatively oppositely with respect to one another. Combining the different dielectric materials and separate layers achieves selected electrical characteristics from the overall capacitor dielectric material. The capacitor dielectric material may be formed with a top layer, a middle layer and a bottom layer. The middle layer may be formed of relatively high leakage dielectric and/or relatively high dielectric constant material, and the top and bottom layers may be formed of barrier material which is substantially resistant to leakage current and which exhibits a relatively lower dielectric constant.
