    摘要: A method of forming air gaps in the interconnect structure of an integrated circuit device. The air gaps may be formed by depositing sacrificial layer over a dielectric layer and then depositing a permeable hard mask over the sacrificial layer. The sacrificial layer is subsequently removed to form air gaps. The permeable hard mask may have a thickness of less than approximately 250 nm, and internal stresses within the permeable hard mask may be controlled to prevent deformation of this layer. Other embodiments are described and claimed.

    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.
