Publication number: 20120073599Abstract: A rinsing liquid adheres to a substrate subjected to a cleaning process. The rinsing liquid on the substrate is first replaced with IPA liquid. While the substrate covered with the IPA liquid is held in a dryer chamber, liquid carbon dioxide is supplied to the surface of the substrate. Liquid nitrogen is supplied to cool down the interior of the dryer chamber. This solidifies the liquid carbon dioxide on the substrate into solid carbon dioxide. Thereafter, the pressure in the dryer chamber is returned to atmospheric pressure, and gaseous nitrogen is supplied into the dryer chamber. Thus, the temperature in the dryer chamber increases.

Patent number: 8029622Abstract: A cooling gas is discharged from a cooling gas discharge nozzle toward a local section of a front surface of a substrate on which a liquid film is formed. And then the cooling gas discharge nozzle moves from a rotational center position of the substrate toward an edge position of the substrate along a moving trajectory while the substrate is rotated. As a result, of the surface region of the front surface of the substrate, an area where the liquid film has been frozen (frozen area) expands toward the periphery edge from the center of the front surface of the substrate. It is therefore possible to form a frozen film all over the front surface of the substrate while suppressing deterioration of the durability of the substrate peripheral members since a section receiving supply of the cooling gas is limited to a local area on the front surface of the substrate.Type: GrantFiled: August 13, 2007Date of Patent: October 4, 2011Assignee: Dainippon Screen Mfg.

Patent number: 7942976Abstract: A rinsing liquid supplier includes a temperature adjuster. The temperature adjuster cools DIW to a temperature lower than room temperature. This temperature adjuster cools down DIW to a temperature not more than 10 degrees centigrade for instance, and cooling down to an even lower temperature of 5 degrees centigrade or below is more preferable. Meanwhile, the temperature adjuster maintains DIW at not less than 0 degrees centigrade, which prevents freezing of the DIW. The cooled DIW supplied to a rinsing liquid pipe is discharged from the rinsing liquid discharge nozzle toward the top surface of the substrate, to thereby form a liquid film. Further, the cooled DIW is discharged toward the rear surface of the substrate from the liquid discharge nozzle via the liquid supply pipe, to thereby form the liquid film on the rear surface. Since the liquid films are already cooled, they are frozen in a short time when the cooling gas is discharged toward the top surface and the rear surface of the substrate.Type: GrantFiled: October 3, 2007Date of Patent: May 17, 2011Assignee: Dainippon Screen Mfg. Co., Ltd.Inventors: Katsuhiko Miya, Akira Izumi

Patent number: 7892361Abstract: An in-chamber member to use in the chamber of a plasma processing vessel has a coating film formed by a coating agent. The in-chamber member having deposits formed on the coating film is separated from the chamber and is immersed into a peeling solvent, e.g., acetone. Since the coating agent is made of a resist formed of a main component of, e.g., cyclized rubber-bisazide and a photosensitive component, the deposits can be separated from the in-chamber member together with the coating film being separated.Type: GrantFiled: April 2, 2008Date of Patent: February 22, 2011Assignee: Tokyo Electron LimitedInventors: Nobuyuki Nagayama, Kouji Mitsuhashi, Hiroyuki Nakayama

Patent number: 7867337Abstract: A substrate having a liquid film formed by pre-processing unit is transported by a substrate transport robot from the pre-processing unit to a freeze processing unit disposed away from the pre-processing unit. In the freeze-processing unit, the liquid film is frozen. This causes the adhesion power of contaminants adhering to the surface of the substrate reduce, and therefore the contaminants is detached from the surface of the substrate. Subsequently, the substrate which was subjected to the freezing process, is transported from the freeze processing unit to a post-processing unit which is disposed away from the pre-processing unit and the freeze processing. In the post-processing unit, a cleaning liquid is supplied to the frozen film on the rotating substrate, thereby easily removing the contaminants adhering to the substrate together with the frozen film.Type: GrantFiled: December 6, 2006Date of Patent: January 11, 2011Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Akira Izumi

Patent number: 7846266Abstract: Cleaning and reclaiming nano-imprint templates using environment friendly methods and systems is disclosed. A template may be cleaned by a combination of exposure to activated gaseous species followed by rinsing with oxygenated or hydrogenated DI water and exposure to reactive plasma to remove organic contaminant. Contaminant may be removed by forming a coating film of a water soluble polymer on the template and then peeling off the coating film. Organic residue from the film may be removed using oxygenated plasma.Type: GrantFiled: February 17, 2006Date of Patent: December 7, 2010Assignee: KLA-Tencor Technologies CorporationInventor: Tony Dibiase

Patent number: 7829146Abstract: Compositions, methods, apparatuses, kits, and combinations are described for neutralizing a stain on a surface. The compositions useful in the present disclosure include a composition that is formulated to be applied and affixed to a surface. If desired, the composition may be substantially removed from the surface to remove a portion or substantially all of the stain before being affixed to the surface. If a user desires to remove the composition from the surface, the composition is formulated to be removed by a number of methods including, for example, vacuuming, wet extraction, chemical application, and the like. If the user desires to affix the composition to the surface in a permanent or semi-permanent manner, the composition may be affixed to the surface by applying energy thereto in the form of, for example, heat, pressure, emitted waves, an emitted electrical field, a magnetic field, and/or a chemical.Type: GrantFiled: December 23, 2008Date of Patent: November 9, 2010Assignee: S.C. Johnson & Son, Inc.Inventors: Ketan N. Shah, James F. Kimball, Marcia L. Santaga, Eric J. Minor

Publication number: 20100229890Abstract: Apparatus and methods for removing particle contaminants from a surface of a substrate includes coating a layer of a viscoelastic material on the surface. The viscoelastic material is coated as a thin film and exhibits substantial liquid-like characteristic. An external force is applied to a first area of the surface coated with the viscoelastic material such that a second area of the surface coated with the viscoelastic material is not substantially subjected to the applied force. The force is applied for a time duration that is shorter than a intrinsic time of the viscoelastic material so as to access solid-like characteristic of the viscoelastic material. The viscoelastic material exhibiting solid-like characteristic interacts at least partially with at least some of the particle contaminants present on the surface.Type: ApplicationFiled: March 10, 2009Publication date: September 16, 2010Applicant: Lam Research Corp.Inventors: Yizhak T.

Patent number: 7790508Abstract: Method for constructing a line or dotted structure on a support, especially for constructing strip-like electrically conducting contacts on a semiconductor component such as a solar cell, by applying an electrically conducting paste-like substance containing a solvent adhering to a support and subsequent hardening of the substance. After the substance is applied to the support, a medium containing a polar molecule is applied on the support and/or the substance, through which the solvent contained in the substance is extracted.Type: GrantFiled: March 8, 2005Date of Patent: September 7, 2010Assignee: Schott Solar AGInventors: Ingo Schwirtlich, Hilmar Von Campe
