Abstract: A method and system for separating impurities, such as large abrasive particles and foreign matter from an abrasive polishing slurry prior to a Chemical Mechanical Polishing (CMP) procedure performed on a surface of a semiconductor wafer. Impurities greater than about 25 microns are removed by an initial filtration process. The filtrate is then introduced to a solid bowl, sedimentation-type centrifuge to remove particles greater than 0.5 microns thereby providing a polishing slurry for final utilization in a CMP procedure that reduces damage to the surface of the polished semiconductor wafer.

Abstract: A method of forming a metal oxide ceramic layer is provided, in which a gaseous flow of a vaporized solution of a precursor organo metal compound in a volatile organic solvent, e.g., plus an oxidizing gas, in the presence of a protonating additive substance and/or activating agent in gaseous state, is conducted into contact with a surface of a substrate. The operation is effected under vacuum pressure at a thermal decomposition temperature for converting the precursor compound to its corresponding metal oxide, e.g., having the same oxidation state as in the precursor compound. The additive substance is present in an amount sufficient for facilitating thermal decomposition of the precursor compound and for controlling the in situ oxidation state of the deposited metal and the amount of oxygen in the formed layer, e.g., while suppressing formation of volatile intermediates and of vacancies in the formed layer.
Abstract: An apparatus for cleaning a reaction chamber which has a chamber, a blade apparatus and a reciprocable rotating unit. The chamber has a wall with an interior surface. The blade apparatus has at least one annular mounting member and at least three scraping blades attached peripherally about the annular mounting member and arranged in a parallel relationship to a longitudinal axis of the chamber. The reciprocable movement unit has a reciprocable member pivotally connected at a peripheral position to the blade apparatus. The reciprocable movement unit rotates the scraping blade(s) circumferentially back and forth along the interior surface of the chamber to scrape its interior surface.

Abstract: A channelized sorbent material comprises porous sorbent particles characterized by an average pore diameter. Each sorbent particle has at least one interior channel of an average transverse dimension (i.e. transverse diameter) that is at least ten times larger than the average pore diameter of the porous sorbent particle. The interior channel may constitute a single cylindrical through-bore in the sorbent particle, or alternatively, an array of intersecting or non-intersecting channels. The porous sorbent particles preferably comprise bead activated carbon particles. Such channelized sorbent material is particular useful as sorbent media in an adsorption-desorption apparatus for storage and dispensing of a sorbable fluid.

Specifically, such electrode assembly comprises a central electrode and a measurement circuit for solution measurement, and an auxiliary electrode and an auxiliary current sourse for generating gas during intervals between solution measurement cycles, so as to remove any solid or liquid residues that may passivate the central electrode, thereby cleaning and rejuvenating the central electrode and preparing it for the next solution measurement cycle.
Abstract: A system for abating undesired component(s) from a gas stream containing same, such as halocompounds, acid gases, silanes, ammonia, etc., by scrubbing of the effluent gas stream with an aqueous scrubbing medium. Halocompounds, such as fluorine, fluorides, perfluorocarbons, and chlorofluorocarbons, may be scrubbed in the presence of a reducing agent, e.g., sodium thiosulfate, ammonium hydroxide, or potassium iodide. In one embodiment, the scrubbing system includes a first acid gas scrubbing unit operated in cocurrent gas/liquid flow, and a second “polishing” unit operated in countercurrent gas/liquid flow, to achieve high removal efficiency with low consumption of water. The scrubbing system may utilize removable insert beds of packing material, packaged in a foraminous containment structure. The abatement system of the invention has particular utility in the treatment of semiconductor manufacturing process effluents.
