US Patent 7365375 Organic-framework zeolite interlayer dielectrics

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.
