    Abstract: Embodiments of the invention generally provide a method of forming an air gap between conductive elements of a semiconductor device, wherein the air gap has a dielectric constant of approximately 1. The air gap may generally be formed by depositing a sacrificial material between the respective conductive elements, depositing a porous layer over the conductive elements and the sacrificial material, and then stripping the sacrificial material out of the space between the respective conductive elements through the porous layer, which leaves an air gap between the respective conductive elements. The sacrificial material may be, for example, a polymerized alpha terpinene layer, the porous layer may be, for example, a porous carbon doped oxide layer, and the stripping process may utilize a UV based curing process, for example.

    Abstract: A method of fabricating an integrated circuit with a dual dielectric structure and utilizes a dual damascene process to fabricate metal interconnection layers. The dual dielectric structure consists of a first insulating layer of conventional dielectric material, and a second insulating layer of a second dielectric material with a low dielectric constant (low-k dielectric material). The first dielectric material is used in regions of the integrated circuit where the superior mechanical properties of conventional dielectric materials will result in maintaining the reliability and mechanical properties of the integrated circuit. The second dielectric material is used in regions of the integrated circuit where the low dielectric constant will result in improved speed of the integrated circuit and reduced electrical coupling between conductors in the integrated circuit. The fabrication of the dual dielectric structure is integrated with a dual damascene metallization process.

    Abstract: A method for manufacturing a semiconductor device having an interlayer insulating film of, e.g., fluorine-added carbon by a simple dual damascene method. An insulating film, e.g., an SiO2 film (3) is formed on a substrate (2), a via hole (31) is made in the SiO2 film (3) by etching, and an upper insulating film, e.g., a CF film (4) is formed over the SiO2 film (3). If the CF film is formed by means of a plasma created from a film forming material having a bad buriability, e.g., C6F6 gas, the CF film is prevented from being buried in the via hole (31) and the CF film (4) is formed over the SiO2 film (3). A trench (41) is made in the CF film (4) by etching, enabling easy formation of a dual damascene having the trench (41) and the via hole (31) integrally continuous with the trench (41).
