Patent number: 8684015Abstract: Strategies for tool designs and their uses wherein the tools can operate in either closed or open modes of operation. The tools easily transition between open and closed modes on demand. According to one general strategy, environmentally controlled pathway(s) couple the ambient to one or more process chambers.

Alternative flows of nonambient fluids can then be introduced into the process chamber(s) via pathways that are at least partially in common with the pathways used for ambient air introduction. In other strategies, gap(s) between moveable components are sealed at least with flowing gas curtains rather than by relying only upon direct physical contact for sealing.Type: GrantFiled: July 13, 2012Date of Patent: April 1, 2014Assignee: Tel FSI, Inc.Inventors: Jeffrey M.

The substrate is dried after the flowing of inert gas is terminated.Type: GrantFiled: December 7, 2011Date of Patent: February 11, 2014Assignee: Intermolecular, Inc.Inventors: Satbir Kahlon, Frank Ma

Patent number: 8637408Abstract: Apparatus and methods are provided for efficiently reclaiming solvents used to clean surfaces of semiconductor wafers, etc. More particularly, embodiments of the present invention provide an in-situ reclaim approach that utilizes condensing mechanisms to reclaim evaporated solvent components. In these embodiments, the condensing can occur within a proximity head itself and/or along a vacuum line running from the proximity head to a vacuum tank. Other embodiments of the present invention provide an in-situ reclaim approach that prevents the evaporation of solvents at the onset by maintaining appropriate equilibrium gas phase concentrations between the liquid chemistries and gases used to process wafer surfaces.Type: GrantFiled: October 4, 2012Date of Patent: January 28, 2014Assignee: Lam Research CorporationInventor: Robert O'Donnell

Patent number: 8635968Abstract: A substrate subjected to back surface cleaning by a back surface cleaning processing unit is held by a hand of an interface transport mechanism and transported to a cooling unit. The substrate whose temperature has been adjusted by the cooling unit is held by a hand of the interface transport mechanism and transported to an exposure device. The substrate subjected to exposure processing by the exposure device is held by a hand of the interface transport mechanism and transported from the exposure device to a substrate platform.Type: GrantFiled: February 2, 2011Date of Patent: January 28, 2014Assignee: Sokudo Co., Ltd.Inventor: Koji Kaneyama

Patent number: 8627836Abstract: A system and method to clean the pellicle frame and adhesive ring of a photomask reticle are described. One embodiment includes a cover that isolates the photomasks from the pellicle frame. The reticle is secured between a spin chuck and the cover so that the photomasks are isolated and protected from solvents used in a cleaning process. With the reticle secured to the spin chuck, the spin chuck is rotated under a pressurized spray of solvent. The solvent, which is caustic to the photomasks, removes the contaminants from the adhesive ring. After the exposed areas are cleaned, the cover is removed and foreign material from photomasks are removed using less invasive solvents and methods.Type: GrantFiled: November 27, 2007Date of Patent: January 14, 2014Assignee: Micron Technology, Inc.Inventors: Shad Hedges, James Baugh

Patent number: 8617409Abstract: A protective chuck is magnetically levitated on a substrate with a gas layer between the bottom surface of the protective chuck and the substrate surface. The gas layer protects a surface region of the substrate against a fluid layer covering the remaining of the substrate surface without contacting the substrate, reducing or eliminating potential damage to the substrate surface. The magnetically levitated protective chuck can enable combinatorial processing of a substrate, providing multiple isolated processing regions on a single substrate with different material and processing conditions.Type: GrantFiled: November 22, 2011Date of Patent: December 31, 2013Assignee: Intermolecular, Inc.Inventors: Rajesh Kelekar, Kent Riley Child

Patent number: 8613803Abstract: Methods for cleaning a surface of a substrate and for increasing the useable lifetime of a photomask substrate are provided. In one method, the surface of a substrate having a contaminating particulate disposed thereon is cleaned by directing a laser towards the substrate, generating a temperature increase in the substrate and transferring thermal energy from the substrate to the particulate to decompose the particulate. The laser has a wavelength that is substantially the same as a local maximum of the substrate absorption spectrum.Type: GrantFiled: October 22, 2012Date of Patent: December 24, 2013Assignee: Rave, LLCInventors: Jeffrey E. LeClaire, Kenneth G. Roessler, David Brinkley
