  • Patent number: 7067616
    Abstract: One or more PTFE films are heated to greater than 150 degrees centigrade (C) and for a time greater than 20 hours, then the PTFE films are cooled. The PTFE films may be heated to temperatures greater than 200° C. and less than 250° C. and most preferably heated to a temperature of about 228° C. The PTFE films may be kept at a temperature for greater than 50 hours or most preferably kept at a temperature for around 100 hours. The PTFE films may be heat processable PTFE fluoropolymer films and may have a number of heat affected zones. The heat affected zones may be created before or after heat treating. The heat affected zones are generally caused by welding two or more PTFE films together, usually under pressure. An “optimal” temperature and “optimal” time period are determined at which heat processed polytetrafluoroethylene (PTFE) fluoropolymers should be heat treated.

  • Patent number: 6989358
    Abstract: A photoresist cleaning composition for removing photoresist and ion implanted photoresist from semiconductor substrates. The cleaning composition contains supercritical CO2 (SCCO2) and alcohol for use in removing photoresist that is not ion-implanted. When the photoresist has been subjected to ion implantation, the cleaning composition additionally contains a fluorine ion source. Such cleaning composition overcomes the intrinsic deficiency of SCCO2 as a cleaning reagent, viz., the non-polar character of SCCO2 and its associated inability to solubilize species such as inorganic salts and polar organic compounds that are present in the photoresist and that must be removed from the semiconductor substrate for efficient cleaning. The cleaning composition enables damage-free, residue-free cleaning of substrates having photoresist or ion implanted photoresist thereon.

  • Patent number: 6984417
    Abstract: A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 ?m. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10?2 ?m2. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).

  • Patent number: 6955198
    Abstract: A gas storage and dispensing system, including multi-vessel arrays of gas dispensing vessels that require successive change-over to provide ongoing supply of gas to a gas-consuming process, with a pump coupled in gas flow communication with the array. The system is provided with capability for time delay auto-switchover sequencing of the switchover operation in which an endpoint limit sensing of an on-stream gas dispensing vessel is responsively followed by termination of gas flow to the pump, inactivation of the pump, autoswitching of vessels, reinitiation of gas flow to the pump and reactivation of the pump. The system minimizes the occurrence of pressure spikes at the pump outlet in response to pressure variation at the pump inlet incident to switchover of gas supply from one vessel to another in the multi-vessel array.

  • Patent number: 6907740
    Abstract: An apparatus and method for charging a gas storage and dispensing vessel with gas to a predetermined pressure level, e.g., a gas to be employed in a semiconductor manufacturing operation such as a hydride, halide or organometallic reagent gas. In the gas charging, a source gas is liquefied, e.g., in a cryotrap, and then gasified in closed flow communication with the vessel to introduce the gas thereinto, and such liquefaction/gasification steps are carried out alternatively and repetitively, to charge the vessel in a step-wise, progressive fashion with gas, until a full fill state is achieved, with the contained gas at the predetermined pressure level.

  • Patent number: 6909772
    Abstract: An apparatus and method for mapping film thickness of textured polycrystalline thin films. Multiple sample films of known thicknesses are provided, and each is irradiated by x-ray at a measurement point to generate a diffraction image that captures a plurality of diffraction arcs. Texture information (i.e., pole densities) of each sample film is calculated based on multiple incomplete pole figures collected from the diffraction image and used to correct the x-ray diffraction intensities obtained from such sample film. Corrected and integrated diffraction intensities of the sample films are then correlated to respective known film thicknesses of such films, and the correlation so determined can be used to map the film thickness of a textured polycrystalline thin film of unknown thickness, based on the corrected and integrated diffraction intensity calculated for such thin film.

  • Patent number: 6897960
    Abstract: A hydrogen gas detector for detection of hydrogen gas in a gaseous environment. The detector comprises a light/heat source, an optical detector, and an optical barrier between the source and detector. The optical barrier responds to the presence of hydrogen by responsively changing from a first optical state to a different second optical state, whereby transmission of light from the light/heat source through the optical barrier is altered by the presence of hydrogen and the altered transmission is sensed by the optical detector to provide an indication of the presence of hydrogen gas in the gaseous environment.
