The nozzles that discharge the streams (14, 16) may be movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1) Or, they may be fixed and the object may be movable relative to them (FIG. 4).Type: GrantFiled: September 15, 2005Date of Patent: March 13, 2007Assignee: Ozone International LLCInventor: Daniel W.

Patent number: 7165563Abstract: An apparatus and a method is provided for decoupling a cavitation in a liquid from an acoustic energy used to induce the cavitation. Broadly speaking, a pressure adjustment is used to control an acoustically induced cavitation in a liquid contained within a wafer cleaning apparatus, wherein the cavitation is defined by an amount and a size of gas bubbles. An increase in a pressure within the wafer cleaning apparatus results in a suppression of the cavitation. Conversely, a decrease in the pressure within the wafer cleaning apparatus results in an enhancement of the cavitation. Thus, independent control of the cavitation is provided without regard to the acoustic energy or a chemistry of the liquid. Controlling the cavitation allows for a safe and efficient wafer cleaning operation that can be customized to address specific requirements dictated by a particular wafer configuration.Type: GrantFiled: December 19, 2002Date of Patent: January 23, 2007Assignee: Lam Research CorporationInventors: John M. Boyd, Michael Ravkin, Fred C. Redecker

Patent number: 7163019Abstract: The present invention relates to a method of cleaning and drying a semiconductor structure in a modified conventional gas etch/rinse or dryer vessel. In an embodiment of the present invention, a semiconductor structure is placed into a first treatment vessel and chemically treated. Following the chemical treatment, the semiconductor structure is transferred directly to a second treatment vessel where it is rinsed with DI water and then dried. The second treatment vessel is flooded with both DI water and a gas that is inert to the ambient, such as nitrogen, to form a DI water bath upon which an inert atmosphere is maintained during rinsing. Next, an inert gas carrier laden with IPA vapor is fed into the second treatment vessel. After sufficient time, a layer of IPA has formed upon the surface of the DI water bath to form an IPA-DI water interface.Type: GrantFiled: August 1, 2003Date of Patent: January 16, 2007Assignee: Micron Technology, Inc.Inventor: Donald L.

Patent number: 7086407Abstract: A high pressure water stream(14) is discharged onto a surface to be cleaned. An ozone/water stream(16) is discharged on the same surface for sanitizing the surface. The high pressure water and ozone/water streams(14,16) are discharged simultaneously along closely adjacent paths that are either parallel (FIG. 3) or concentric (FIG. 2). The water pressure is at least about 100 p.s.i. and is preferably between 100 p.s.i. and 2000 p.s.i. The nozzles that discharge the streams (14,16) maybe movable relative to the object(s) that receives the high pressure water and ozone/water (FIG. 1). Or, they may be fixed and the object may be movable relative to them (FIG. 4).Type: GrantFiled: January 9, 2004Date of Patent: August 8, 2006Assignee: Ozone International LLCInventor: Daniel W. Lynn

Patent number: 7000623Abstract: Methods and systems for preparing a substrate implementing a surface tension reducing process are provided. In one example, a substrate preparation system includes a chuck which fingers for edge gripping the substrate. The chuck is hollow to provide simultaneous access to both active and backside surfaces of the substrate, and is configured to rotate the substrate. The system includes dispense arms positioned over the substrate surfaces. The dispense arms are capable of moving between a center region and a periphery of the substrate surfaces, and each dispense arm includes a pair of supply lines for delivering fluids over the substrate surfaces. A connection couples the upper dispense arm with the lower dispense arm so that the dispense arms synchronously move between the center region and the periphery of the substrate, and remain aligned on opposite surfaces of the substrate.Type: GrantFiled: May 17, 2002Date of Patent: February 21, 2006Assignee: Lam Research CorporationInventors: Christopher M.
