Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organo silane compound and an oxidizing gas. The oxidized organo silane film has excellent barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organo silane film can also be used as an etch stop or an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organo silane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organo silane film is produced by reaction of methyl silane, CH3SiH3, and N2O.

Abstract: This invention provides a stable process for depositing an antireflective layer. Helium gas is used to lower the deposition rate of plasma-enhanced silane oxide, silane oxynitride, and silane nitride processes. Helium is also used to stabilize the process, so that different films can be deposited. The invention also provides conditions under which process parameters can be controlled to produce antireflective layers with varying optimum refractive index, absorptive index, and thickness for obtaining the desired optical behavior.

Abstract: The invention relates to a method of treatment of collagenous connective tissue removed from a donor for implant into a recipient which is re-habited or re-colonized by host cells without an immune rejection and inflammatory reaction. After removal from the donor, the tissue is trimmed and thereafter soaked in a cold stabilizing solution having a temperature range of 4 to 10 degrees centigrade. The tissue is then soaked at a predetermined temperature in a polyglycol, salt, hydrogen peroxide, and phosphate buffer first solution of predetermined quantities and concentrations and of sufficient ionic strength to permit ground substances to dissociate such that the collagen fibers remain stable. The tissue is then soaked in an alcohol and water solution at a predetermined temperature for a sufficient period of time to remove the residue of the first solution. Following the removal of the residue, the tissue is soaked at a predetermined temperature in a third solution of an anti-inflammatory agent, an anti-thrombic agent, alcohol, and water or sequentially in an anti-inflammatory agent, alcohol, and water solution, and then in an anti-thrombic agent, alcohol and water solution and thereafter stored.

Abstract: An apparatus for preventing particulate matter and residue build-up within a vacuum exhaust line of a semiconductor processing device. The apparatus uses RF energy to form excite the constituents of particulate matter exhausted from a semiconductor processing chamber into a plasma state such that the constituents react to form gaseous products that may be pumped through the vacuum line. The apparatus may include a collection chamber structured and arranged to collect particulate matter flowing through the apparatus and inhibiting egress of the particulate matter from the apparatus. The apparatus may further include an electrostatic collector to enhance particle collection in the collection chamber and to further inhibit egress of the particulate matter.

Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organosilicon compound and an oxidizing gas at a constant RF power level from about 10W to about 200W or a pulsed RF power level from about 20W to about 500W. Dissociation of the oxidizing gas can be increased prior to mixing with the organosilicon compound, preferably within a separate microwave chamber, to assist in controlling the carbon content of the deposited film. 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 and 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, dimethylsilane, (CH3)2SiH2, or 1,1,3,3-tetramethyl-disiloxane, (CH3)2—SiH—O—SiH—(CH3)2, and nitrous oxide, N2O, at a constant RF power level from about 10W to about 150W, or a pulsed RF power level from about 20W to about 250W during 10% to 30% of the duty cycle.

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.
