    摘要: A low-k dielectric sacrificial material is formed within a microelectronic structure covered with a layer defining an exhaust vent. At an appropriate time, the underlying sacrificial material is decomposed and exhausted away through the exhaust vent. Residue from the exhausted sacrificial material accumulates at the vent location during exhaustion until the vent is substantially occluded. As a result, an air gap is created having desirable characteristics as a dielectric.

    摘要: An organic-framework zeolite interlayer dielectric is disclosed. The interlayer dielectric's resistance to chemical attack, its dielectric constant, its mechanical strength, or combinations thereof can be tailored by (1) varying the ratio of carbon-to-oxygen in the organic-framework zeolite, (2) by including tetravalent atoms other than silicon at tetrahedral sites in the organic-framework zeolite, or (3) by including combinations of pentavalent/trivalent atoms at tetrahedral sites in the organic-framework zeolite.
