  • Patent number: 6661049
    Abstract: Within a method for fabricating a capacitor structure, and a capacitor structure fabricated employing the method, there is formed within an isolation region adjoining an active region of a semiconductor substrate a laterally asymmetric trench which leaves exposed an upper sidewall portion of the active region of the semiconductor substrate. There is then formed within the laterally asymmetric trench a capacitor node layer which contacts the exposed upper sidewall portion of the active region of the semiconductor substrate and extends above the active region of the semiconductor substrate. The capacitor may be a storage capacitor with increased capacitance fabricated within a memory cell structure of decreased dimensions.

  • Patent number: 6638813
    Abstract: A process for forming a composite insulator spacer on the sides of a buried stack capacitor structure, wherein the buried stack capacitor structure is located overlying a portion of an insulator filled, shallow trench isolation (STI) region, has been developed. A thin silicon nitride spacer is first formed on the sides of the completed buried stack capacitor structure, followed by deposition of a silicon oxide layer. An anisotropic dry etch procedure is next employed removing a top portion of the silicon oxide layer, and resulting in a partially defined silicon oxide spacer. A critical wet etch procedure is next used to remove the bottom portion of the silicon oxide layer, defining the final silicon oxide spacer of the composite insulator spacer, now comprised of a silicon oxide spacer on an underlying silicon nitride spacer.
