  • Patent number: 7242074
    Abstract: A method for reducing the parasitic capacitance in resistors, and a resistor design embodying this method are described. By creating a p-type or an n-type implant inside of an n-well or a p-substrate, respectively, where the n-well or p-substrate is located in a p-substrate or n-substrate, respectively, a capacitively coupled capacitor is formed in series connection with the parasitic inter-layer dielectric capacitance generated when the resistor is fabricated in the dielectric material. The depletion region formed thereby behaves as a series capacitor which reduces the overall capacitance of the assemblage. The n-well or p-substrate can be placed in electrical connection with a ground potential or brought to a chosen voltage to further increase the depletion region and reduce the capacitance of the resistor.
