    Abstract: 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.

    Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organosilane or organosiloxane compound and an oxidizing gas at a low RF power level from 10-250 W. The oxidized organosilane or organosiloxane film has good barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organosilane or organosiloxane film may also be used as an etch stop or an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organosilane or organosiloxane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organosilane film is produced by reaction of methylsilane, CH3SiH3, or dimethylsilane, (CH3)2SiH2, and nitrous oxide, N2O, at an RF power level from about 10 to 200 W or a pulsed RF power level from about 20 to 250 W during 10-30% of the duty cycle.

    Abstract: A method and apparatus for depositing an etch stop layer. The method begins by introducing process gases into a processing chamber in which a substrate is disposed. An etch stop layer is then deposited over the substrate. An overlying layer is then deposited over the etch stop layer. The etch stop layer substantially protects underlying materials from the etchants used in patterning the overlying layer. Moreover, the etch stop layer also possesses advantageous optical characteristics, making it suitable for use as an antireflective coating in the patterning of layers underlying the etch stop layer.

    Abstract: A planarized passivation layer is described. A planarized passivation layer of the present invention preferably includes a fluorosilicate glass (FSG) layer and a silicon nitride layer. The FSG layer is preferably deposited using triethoxyfluorosilane (TEFS) and tetraethoxyorthosilicate (TEOS). The inclusion of fluorine in the process chemistry provides good gap-fill characteristics in the film thus formed. The TEFS-based process employed by the present invention employs a low deposition rate, on the order of less than about 4500 .ANG./min, and preferably above 3000 .ANG./min, when depositing the FSG layer. The use of low deposition rate results in a positively sloped profile, preventing the formation of voids during the deposition of the FSG layer and the silicon nitride layer.
