  • Publication number: 20060283486
    Abstract: A method for cleaning a substrate is provided. In this method, a flow of non-Newtonian fluid is provided where at least a portion of the flow exhibits plug flow. To remove particles from a surface of the substrate, the surface of the substrate is placed in contact with the portion of the flow that exhibits plug flow such that the portion of the flow exhibiting plug flow moves over the surface of the substrate. Additional methods and apparatuses for cleaning a substrate also are described.

  • Publication number: 20060285930
    Abstract: A method for transporting a substrate is provided. In this method, a non-Newtonian fluid is provided and the substrate is suspended in the non-Newtonian fluid. The non-Newtonian fluid is capable of supporting the substrate. Thereafter, a supply force is applied on the non-Newtonian fluid to cause the non-Newtonian fluid to flow, whereby the flow is capable of moving the substrate along a direction of the flow. Apparatuses and systems for transporting the substrate using the non-Newtonian fluid also are described.

  • Publication number: 20060207636
    Abstract: A substrate preparation apparatus is provided. The apparatus includes a housing configured to be installed in a substrate fabrication facility. The housing includes a manifold for use in preparing a wafer surface. The manifold is configured to include a first process window in a first portion of the manifold. A first fluid meniscus is capable of being defined within the first process window. Further included is a second process window in a second portion of the manifold. A second fluid meniscus is capable of being defined within the second process window. An arm is integrated with the housing, and the arm is coupled to the manifold, such that the arm is capable of positioning the manifold in proximity with the substrate during operation. The apparatus therefore provides for the formation of multi-menisci over the surface of a substrate using a single manifold.

  • Patent number: 7029369
    Abstract: An apparatus is provided for polishing a substrate. The apparatus includes a polishing pad configured to traverse from at least a first point to a second point. A first sensor is located near the first point and oriented so as to sense an incoming temperature of the polishing pad. A second sensor is located near the second point and oriented so as to sense an outgoing temperature of the polishing pad. A difference between the incoming temperature and the outgoing temperature is then used to determine endpoint of a polishing operation.

  • Publication number: 20050132953
    Abstract: A apparatus for drying a substrate includes a vacuum manifold positioned adjacent to an edge wheel. The edge wheel includes an edge wheel groove for receiving a peripheral edge of a substrate, and the edge wheel is capable of rotating the substrate at a desired set velocity. The vacuum manifold includes a proximity end having one or more vacuum ports defined therein. The proximity end is positioned at least partially within the edge wheel groove, and using supplied vacuum removes fluids that accumulate in the edge wheel groove and prevents re-deposit of trapped fluids around the peripheral edge of the substrate.

  • Publication number: 20050133060
    Abstract: An apparatus and method are disclosed in which a semiconductor substrate having a surface containing contaminants is cleaned or otherwise subjected to chemical treatment using a foam. The semiconductor wafer is supported either on a stiff support (or a layer of foam) and foam is provided on the opposite surface of the semiconductor wafer while the semiconductor wafer is supported. The foam contacting the semiconductor wafer is pressurized using a form to produce a jammed foam. Relative movement between the form and the semiconductor wafer, such as oscillation parallel and/or perpendicular to the top surface of the semiconductor wafer, is then induced while the jammed foam is in contact with the semiconductor wafer to remove the undesired contaminants and/or otherwise chemically treat the surface of the semiconductor wafer using the foam.

  • Publication number: 20050121059
    Abstract: A single substrate cleaning apparatus that prevents galvanic corrosion is provided. The apparatus includes a spindle configured to rotatably support a substrate. A moveable dispense arm disposed over the spindle is included. The dispense arm supports a first supply line and a second supply line. The first supply line has a first nozzle affixed to an end of the first supply line, and the second supply line has a second nozzle affixed to an end of the second supply line. The first nozzle is positioned behind the second nozzle such that a fluid dispensed from the second nozzle is dried by application of a fluid simultaneously dispensed from the first nozzle in manner that protects the substrate from galvanic corrosion.

  • Patent number: 6858091
    Abstract: A method for minimizing galvanic corrosion effects in a single-wafer cleaning system is provided. The method initiates with spraying a cleaning chemistry containing corrosion inhibitors onto a surface of a wafer. Then, the surface of the wafer is exposed to the cleaning chemistry for a period of time. Next, a concentration gradient at an interface of the cleaning chemistry and the surface of the wafer is refreshed. Then, a rinsing agent and a drying agent are applied simultaneously to remove the cleaning chemistry, wherein the drying agent dries the surface of the wafer prior to a concentration of the corrosion inhibitors being diluted to a level insufficient to provide corrosion protection.

  • Patent number: 6827793
    Abstract: A method for cleaning a wafer with a drip nozzle being configured for use in a drip manifold that is oriented over a brush of a wafer cleaning system is provided. The drip nozzle has a first end and a second end with a passage defined there between where the passage includes a wall that extends longitudinally between the first end and the second end. An orifice is defined within the passage and located at the first end of the drip nozzle. The method includes inputting a fluid into the drip nozzle at an acute angle relative to a longitudinal extension of the wall and reflecting the fluid stream off an internal wall of the drip nozzle at least twice in a direction that is toward the second end. The method further includes outputting at least one substantially uniform drop from the second end of the passage.

  • Publication number: 20040216764
    Abstract: A method and a system are provided for cleaning a surface of a wafer. The method starts by scrubbing the surface of the wafer with a cleaning brush that applies a chemical solution to the surface of the wafer. In one example, the cleaning brush implements a through the brush (TTB) technique to apply the chemicals. The scrubbing is generally performed in a brush box, with a top cleaning brush and a bottom cleaning brush. The top cleaning brush is then removed from contact with the surface of the wafer. The chemical concentration in the top brush may be maintained at substantially the same concentration that was in the brush during the scrubbing operation. Next, a flow of water (preferably de-ionized water) is delivered to the surface of the wafer. The delivery of water is preferably configured to remove substantially all of the chemical solution from the surface of the wafer before proceeding to a next cleaning operation.

  • Patent number: 6726530
    Abstract: Chemical mechanical polishing systems and methods are disclosed. The system includes a polishing pad that is configured to move from a first point to a second point. A carrier is also included and is configured to hold a substrate to be polished over the polishing pad. The carrier is designed to apply the substrate to the polishing pad in a polish location that is between the first point and the second point. A first sensor is located at the first point and oriented so as to sense an IN temperature of the polishing pad, and a second sensor is located a the second point and oriented so as to sense an OUT temperature of the polishing pad. The sensing of the IN and OUT temperatures is configured to produce a temperature differential that allows monitoring the process state and the state of the wafer surface for purposes of switching the process steps while processing wafers by chemical mechanical planarization.
