    摘要: A method of fabricating relaxed SiGe buffer layers with low threading dislocation densities on silicon-on-insulator (SOI) substrates is provided. The relaxed SiGe buffer layers are fabricated by the epitaxial deposition of a defect-free Stranski-Krastanov Ge or SiGe islands on a surface of the SOI substrate; the capping and planarizing of the islands with a Si or Si-rich SiGe layer, and the annealing of the structure at elevated temperatures until intermixing and thereby formation of a relaxed SiGe layer on the insulating layer (i.e., buried oxide layer) of the initial SOI wafer is achieved. The present invention is also directed to semiconductor structures, devices and integrated circuits which include at least the relaxed SiGe buffer layer mentioned above.

    摘要: A method for fabricating a thermally stable carbon-based low dielectric constant film such as a hydrogenated amorphous carbon film or a diamond-like carbon film in a parallel plate chemical vapor deposition process utilizing plasma enhanced chemical vapor deposition process is disclosed. Electronic devices containing insulating layers of thermally stable carbon-based low dielectric constant materials that are prepared by the method are further disclosed. In order to render the carbon-based low dielectric constant film thermally stable, i.e., at a temperature of at least 400° C., the films are heat treated at a temperature of not less than 350° C. for at least 0.5 hour. To enable the fabrication of thermally stable carbon-based low dielectric constant film, specific precursor materials such as cyclic hydrocarbons should be used, for instance, cyclohexane or benzene. The geometry of the chemical vapor deposition chamber is important in making the present invention thermally stable low dielectric constant films in order to achieve a specific bias voltage on the substrate onto which the electronic structure is formed.

    摘要: A structured dielectric layer and fabrication process for separating wiring levels and wires within a level on a semiconductor chip is described incorporating a lower dielectric layer having narrow air gaps to form dielectric pillars or lines and an upper dielectric layer formed over the pillars or fine lines wherein the air gaps function to substantially reduce the effective dielectric constant of the structured layer. The invention overcomes the problem of solid dielectric layers which would have the higher dielectric constant of the solid material used.

    摘要: An electron cyclotron resonance plasma heating apparatus system and process in which microwave energy is transmitted directly in an axial direction through an evacuated chamber to generate energetic electrons. These energetic electrons spiral around the magnetic field lines formed by the solenoid and spiral substantially parallel to the axis. A metal atom vapor source transmits the metal atom vapor into the chamber through a housing port in the chamber wall. The metal atom vapor source in the housing is out of the line of sight of the substrate. The metal atoms are ionized by the energized electrons, and these ionized metal atoms are confined to the plasma column substantially free of neutral atoms as such ionized metal approaches and contacts the substrate in said evacuated chamber. In this way, the ionized metal atoms substantially avoid contact with the wall of chamber. A sputter target of a second metal may be placed in the plane of the substrate and a bias voltage applied to the target. Atoms of the second metal are then sputtered off and ionized by the plasma and are deposited on the substrate with the first metal ions.
