摘要： A method for forming holes in the backside dielectric layer of solar cells for fabrication of rear point contact. The backside dielectric layer is coated with a layer of carbon. A shadow mask is placed over the carbon layer and reactive ion etch (RIE) is used to transfer the holes in the shadow mask to the carbon layer, to thereby form a carbon mask. The shadow mask is then removed and RIE is used to transfer the holes from the carbon mask to the dielectric layer. The carbon mask is then removed by, e.g., ashing.

摘要： The present invention provides a SiC material, formed according to certain process regimes, useful as a barrier layer, etch stop, and/or an ARC, in multiple levels, including the pre-metal dielectric (PMD) level, in IC applications and provides a dielectric layer deposited in situ with the SiC material for the barrier layers, and etch stops, and ARCs. The dielectric layer can be deposited with different precursors as the SiC material, but preferably with the same or similar precursors as the SiC material. The present invention is particularly useful for ICs using high diffusion copper as a conductive material. The invention may also utilize a plasma containing a reducing agent, such as ammonia, to reduce any oxides that may occur, particularly on metal surfaces such as copper filled features. The invention also provides processing regimes that include using an organosilane as a silicon and carbon source, perhaps independently of any other carbon source or hydrogen source, and preferably in the absence of a substantial amount of oxygen to produce a SiC with a dielectric constant of less than 7.0. This particular SiC material is useful in complex structures, such as a damascene structure and is conducive to in situ deposition, especially when used in multiple capacities for the different layers, such as the barrier layer, the etch stop, and the ARC and can include in situ deposition of the associated dielectric layer(s).

摘要： The present invention generally provides improved adhesion and oxidation resistance of carbon-containing layers without the need for an additional deposited layer. In one aspect, the invention treats an exposed surface of carbon-containing material, such as silicon carbide, with an inert gas plasma, such as a helium (He), argon (Ar), or other inert gas plasma, or an oxygen-containing plasma such as a nitrous oxide (N2O) plasma. Other carbon-containing materials can include organic polymeric materials, amorphous carbon, amorphous fluorocarbon, carbon containing oxides, and other carbon-containing materials. The plasma treatment is preferably performed in situ following the deposition of the layer to be treated. Preferably, the processing chamber in which in situ deposition and plasma treatment occurs is configured to deliver the same or similar precursors for the carbon-containing layer(s). However, the layer(s) can be deposited with different precursors. The invention also provides processing regimes that generate the treatment plasma and systems which use the treatment plasma. The carbon-containing material can be used in a variety of layers, such as barrier layers, etch stops, ARCs, passivation layers, and dielectric layers.

摘要： The present invention provides an in situ plasma reducing process to reduce oxides or other contaminants, using a compound of nitrogen and hydrogen, typically ammonia, at relatively low temperatures prior to depositing a subsequent layer thereon. The adhesion characteristics of the layers are improved and oxygen presence is reduced compared to the typical physical sputter cleaning process of an oxide layer. This process may be particularly useful for the complex requirements of a dual damascene structure, especially with copper applications.

摘要： A substrate processing system that includes a ceramic substrate holder having an RF electrode embedded within the substrate holder and a gas inlet manifold spaced apart from the substrate holder. The gas inlet manifold supplies one or more process gases through multiple conical holes to a reaction zone of a substrate processing chamber within the processing system and also acts as a second RF electrode. Each conical hole has an outlet that opens into the reaction zone and an inlet spaced apart from the outlet that is smaller in diameter than said outlet. A mixed frequency RF power supply is connected to the substrate processing system with a high frequency RF power source connected to the gas inlet manifold electrode and a low frequency RF power source connected to the substrate holder electrode. An RF filter and matching network decouples the high frequency waveform from the low frequency waveform. Such a configuration allows for an enlarged process regime and provides for deposition of films, including silicon nitride films, having physical characteristics that were previously unattainable.

摘要： A method of depositing and etching dielectric layers having low dielectric constants and etch rates that vary by at least 3:1 for formation of horizontal interconnects. The amount of carbon or hydrogen in the dielectric layer is varied by changes in deposition conditions to provide low k dielectric layers that can replace etch stop layers or conventional dielectric layers in damascene applications. A dual damascene structure having two or more dielectric layers with dielectric constants lower than about 4 can be deposited in a single reactor and then etched to form vertical and horizontal interconnects by varying the concentration of a carbon:oxygen gas such as carbon monoxide. The etch gases for forming vertical interconnects preferably comprises CO and a fluorocarbon, and CO is preferably excluded from etch gases for forming horizontal interconnects.

摘要： The present invention relates to chemical modifications of the surfaces of silicalite and high-silica zeolite nanoparticles permitting such particles to be dispersed in nonpolar hydrophobic solvents, and to the dispersions so produced and to interlayer dielectric layers, molecular sieve membranes and/or catalytic membranes formed from such dispersions, and to the fabrication of integrated circuits in the case of interlayer dielectric layers. A dispersion of silicalite or high-silica zeolite nanoparticles is formed in alkaline aqueous solution. The pH of the solution is reduced by multiple rinsing with deionized water to approximately pH of 9 or 10. The solution is then rendered acidic, typically pH between 2 and 3, by the addition of a suitable acid. The acidic solution is gradually intermixed with an alcohol under conditions of elevated temperature and/or reduced pressure to enhance the solvent evaporation rate. In this form, the silicalite or high-silica zeolite nanoparticles are reacted with reactants to cause the silanol groups on the surface to form direct silicon-hydrocarbon bonds or, in alternative embodiments, to undergo etherification. The silicalite particles thus modified may be redispersed into nonpolar solvents suitable for combination with binding agents and for the formation of dielectric layers on integrated circuits.

摘要： A silicon oxide film is deposited on a substrate by first introducing a process gas into a chamber. The process gas includes a gaseous source of silicon (such as silane), a gaseous source of fluorine (such as SiF4), a gaseous source of oxygen (such as nitrous oxide), and a gaseous source of nitrogen (such as N2). A plasma is formed from the process gas by applying a RF power component. Deposition is carried out at a rate of at least about 1.5 &mgr;m/min. The resulting FSG film is stable and has a low dielectric constant.
