  • Patent number: 6692579
    Abstract: A method for cleaning a semiconductor structure using vapor phase condensation with a thermally vaporized cleaning agent, a hydrocarbon vaporized by pressure variation, or a combination of the two. In the thermally vaporized cleaning agent process, a semiconductor structure is lowered into a vapor blanket in a thermal gradient cleaning chamber at atmospheric pressure formed by heating a liquid cleaning agent below the vapor blanket and cooling the liquid cleaning agent above the vapor blanket causing it to condense and return to the bottom of the thermal gradient cleaning chamber. The semiconductor structure is then raised above the vapor blanket and the cleaning agent condenses on all of the surfaces of the semiconductor structure removing contaminants and is returned to the bottom of the chamber by gravity.

  • Patent number: 6693038
    Abstract: A method for forming within a dielectric layer upon a substrate within a microelectronics fabrication a series of contact via holes etched through the dielectric layer to multi-level contact layers employing reactive plasma etching methods to form the series of contact via holes. The first plasma etch method employs fluorine containing gases to form the etched via holes, and then the second plasma etch method employs oxygen and a fluorocarbon gas to complete the etching of the via holes and remove residual materials. The etched via holes access multi-level contact layers formed upon the substrate at differing heights with respect to the substrate, penetrating through at least one contact layer. This permits formation of a series of electrical contacts, between the series of contact layers and patterned conductor layers through the series of via holes, with low electrical resistances.
