  • Integrated capacitor with a mixed dielectric
    Patent number: 6501151
    Abstract: An integrated circuit capacitor includes a substrate, a first metal electrode on the substrate, and a dielectric layer on the first metal electrode. The dielectric layer includes a homogeneous combination of at least two dielectric materials having permittivities varying in an opposite way based upon an electric field, with a proportion of each dielectric material being chosen so that the integrated circuit capacitor has a desired voltage linearity. A second metal electrode is on the dielectric layer.
