  • Patent number: 7833381
    Abstract: The present invention provides a method and apparatus for improving optical sensing of a plasma process through the use of a fiber optic sensor placed within a standard showerhead hole of a standard gas showerhead positioned in an upper electrode of a plasma system during the plasma processing of a substrate. A film property can be calculated based on the measured plasma emission from the surface of the substrate. The film property can be film deposition rate, refractive index, film thickness, etc. Based on the measured film property, the plasma processing of the substrate can be adjusted and/or terminated. In addition, a window is provided that is positioned in the upper electrode assembly for viewing the plasma emission through the standard showerhead hole.

  • Patent number: 7829465
    Abstract: The present invention provides a method of etching features in a substrate. The method comprising the steps of placing the substrate on a substrate support in a vacuum chamber. An alternatingly and repeating process is performed on the substrate until a predetermined trench depth and a predetermined sidewall angle are achieved. One part of the process is a deposition step which is carried out by introducing at least one polymer containing gas into the vacuum chamber. A plasma is ignited from the polymer containing gas which is then used to deposit a polymer on the substrate. The other part of the alternatingly and repeating process is an etching step which is carried out by introducing an etchant containing gas, a polymer containing gas and a scavenger containing gas into the vacuum chamber. A plasma is ignited from the etchant containing gas, the polymer containing gas and the scavenger containing gas which is then used to etch the substrate.

  • Patent number: 7513936
    Abstract: The gas chromatography (GC) column assembly described herein consists of capillary GC column material, such as fused silica or metal capillary tubing, which is constrained to lie in a flat, ordered, spiral pattern and then encased between two thin opposing surfaces. The resulting column assembly is flat, dimensionally stable and can be very efficiently thermally modulated. The resulting column assembly also takes up very little space, has very little thermal mass, and can be easily and accurately manufactured. The column assembly can be adapted for chromatographic use by affixing it to the surface of a thermal modulator described herein by means of adhesive force or by mechanical compression, and then by attaching the free ends of the exposed column material to the input and output ports of the chromatographic device.

  • Patent number: 7509160
    Abstract: The present invention is a cardiac rhythm-monitoring device, which allows patients to perform a preliminary screening for supraventricular arrhythmia. The device detects beat-to-beat heart rhythms (i.e. the R-R interval between individual heart beats) and performs a screening test to determine if there are indications of arrhythmia. The test looks for variance in the R-R interval that is outside of the normal range, either using a pre-constructed chart based upon general population studies to determine the normal range of variance or using normal distribution analysis of the patient's own heart rhythm to determine the normal range of variance for determining irregular heartbeats, and if there are multiple irregularities within the sensed time frame, the patient is warned of potential supraventricular arrhythmia. By sensing both electrical impulses form the heart and mechanical responses to the heartbeat, the device may augment its analysis.

  • Patent number: 7448661
    Abstract: Disclosed is a pallet loading and unloading sling, termed a SlingBag device, for efficiently transporting burlap bags and deploying them to secure and protect underwater pipelines. In preferred form, the SlingBag is a T-shaped mat that folds up into a four-sided bag. By using a SlingBag atop a wooden pallet, the process for loading and unloading burlap bags from the pallet may be simplified The SlingBag comprises two rectangular mats that are arranged in a perpendicular cross section, forming a T-shaped mat. When placed upon a pallet for loading, the central panel fits atop the pallet, and the four side flaps extend outward. Burlap bags filled with dry bulk sand or dry sand/cement mix are stacked atop the pallet with the SlingBag. Then, the side flaps are folded up to form a four-sided sling container, and the lifting loops on the side panels are tied in place to secure the sling. In the preferred embodiment, the SlingBag is comprised of polypropylene.

  • Patent number: 7250220
    Abstract: An improved component for use in a deposition chamber is constructed from ceramic zirconia and a stabilizing compound. The zirconia is preferably in a partially stabilized form and is coated with a metallic layer such as thermally sprayed aluminum. The surface of the zirconia is roughened to improve adhesion between the zirconia and the aluminum. Alternatively, an intermediate layer may be deposed between the zirconia and the metallic layer to improve the bonding between the layers. The coated zirconia component resists flaking when covered with materials that are being deposited in the deposition chamber and, thus, reduces the likelihood that devices being constructed in the deposition chamber will be contaminated by loose particles.

  • Patent number: 7115520
    Abstract: The present invention provides a method for controlling pressure in a vacuum chamber during a time division multiplexed process. A throttle valve is pre-positioned and held for a predetermined period of time. A process gas is introduced into the vacuum chamber during the associated plasma step (deposition or etching) of the silicon wafer. At the end of the predetermined period of time, the process gas continues to flow with the throttle valve being released from the set position. At this point, the throttle valve is regulated through a proportional derivative and integral control for a period that lasts the remaining time of the associated plasma step.

  • Patent number: 7029205
    Abstract: Disclosed is an apparatus for pipeline stabilization and shoreline erosion protection, termed a BulkMat device, for protecting and securing pipelines, which are typically located in ditches or on the floor of large bodies of water. In preferred form, the BulkMat comprises a long fabric mat with four to eight fabric compartments sewn onto the mat and filled with dry bulk sand/cement mix. In the preferred embodiment, the BulkMat is comprised of polypropylene. The BulkMat has four lifting loops that are used to pick-up and lower the BulkMat onto the desired location. When the bulk mat is placed on the location, and water sets in, the sand/cement mix in the compartments will harden to concrete. By hardening after it is set in place, the BulkMat will conform completely to the pipeline or covered area to be protected, precisely matching the specific area.

  • Patent number: 6982033
    Abstract: The Aerobic Treatment Plant with Filter Pipe (“ATPFP”) processes sewage for buildings not connected to a municipal sewer system. It employs a multi-stage process for cleaning sewage in a single, light-weight, easy-to-install unit. Sewage is initially cleaned in the aerobic tank, which is divided into an inner chamber and an outer chamber by a funnel-shaped clarifier hanging down in the aerobic tank, with the opening in the bottom of the clarifier held above the bottom of the aerobic tank. Air droplines hang down in the outer chamber of the aerobic tank, so that sewage in the outer chamber is aerated, stimulating aerobic microorganisms which digest the sewage. The sewage in the outer chamber then moves into the inner chamber inside the clarifier where gravity separates solids from the effluent. This cleaned effluent is then drained to the post-treatment tank for additional cleaning, where it may be chlorinated before it is filtered to screen out debris and then stored for discharge.
