Patent number: 6517637Abstract: The present invention provides a method for cleaning wafer surfaces in a scrubber by ion doped deionized water without the electrostatic discharge problem. The method can be carried out by first doping a quantity of deionized water with at least one species of ions from the group consisting of OH−, F−, Cl−, NH4+ and H+ any other suitable ions. The added ions significantly reduce the resistivity of the DI water such that DI water is no longer a perfect insulator and therefore, when sprayed onto wafer surfaces covered by an insulating material, the generation of electrostatic charges is significantly reduced. As a result, the undesirable effect of electrostatic discharge can be significantly reduced or eliminated and the yield of the wafer fabrication process can be improved.Type: GrantFiled: July 23, 1997Date of Patent: February 11, 2003Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Chiang Fu, Yu-Chyi Harn

Patent number: 6494963Abstract: A scraper head of a scraping tool includes (i) a base having a longitudinal axis, longitudinally opposing first and second ends, and an interior threaded surface defining a longitudinally extending cavity within the base, the cavity having an open end at the first base end and a closed end within the base, and (ii) a pair of blades extending from the second base end so as to terminate in respective end portions which converge to a tip aligned with the base axis. The cavity in the base of the scraper head can threadedly and securely receive the threaded end portion of an extension pole. In use, the tip of the scraper head is positioned at the junction between a textured ceiling and a wall, and the scraper head is moved with the extension pole along the junction such that the blade end portions cut away excess texture material. A straight line is created at the junction in preparation for painting of the wall.Type: GrantFiled: October 12, 2001Date of Patent: December 17, 2002Inventor: Kennith P. Holly

Publication number: 20020184720Abstract: A system and methods for substrate preparation are provided. In one example, a wafer processing system includes a system enclosure that contains wafer processing apparatus within an isolated wafer processing environment. The wafer processing apparatus include a pair of immersion tanks in the lower front region of the system with a pair of wafer pickers behind the immersion tanks to extract wafers from the tanks. In the rear of the system, a pair of brush boxes are located in a lower region with a pair of dryer units positioned above the brush boxes. A robot arm is positioned between the pair of immersion tanks and the pair of brush boxes in a middle region of the system, and is configured to transition wafers between the processing apparatus. A pair of output shelves holding output cassettes is positioned over the immersion tanks. The output cassettes receive clean wafers after processing. In another example, a method for preparing a substrate is provided.Type: ApplicationFiled: August 1, 2002Publication date: December 12, 2002Applicant: Lam Research Corp.Inventors: David T. Frost, Oliver David Jones, Mike Wallis

Publication number: 20020187912Abstract: Methods for cleaning screw extruder, especially powder-coating extruders, include filling the extruder barrel with a gel purge formulation comprised of a high-boiling pyrrolidone or piperidone (lactam) solvent (most preferably N-methyl pyrrolidone (NMP)), thickened with 5-50 wt. % of a thermoplastic resin thickening agent, most preferably polystyrene (PS). Once the extruder barrel is filled with the gel purge formulation, the screws are stopped and the gel allowed to soak for between about 10 to about 30 minutes. The screws are then restarted and the gel is discharged from the extruder. Immediately after the gel purge formulation exits the machine, a small amount of a thermoplastic “rinse” polymer (e.g., polyethylene) may be added so as to remove any vestigial amount of the gel purge formulation therefrom.Type: ApplicationFiled: June 6, 2001Publication date: December 12, 2002Inventor: Mark W.

Publication number: 20020179116Abstract: A surface maintenance apparatus is described, having a sweeping system positioned near the front or leading edge of the apparatus. The sweeping system includes a plurality of brushes and a removable hopper for collecting debris. The sweeping system is capable of being raised off the surface being maintained when the sweeping system encounters an obstacle or irregularity on the surface. The brushes are pivotally mounted to the surface maintenance apparatus to allow the brushes to be rotated away from each other, providing access to the removable hopper from the front end of the surface maintenance apparatus.Type: ApplicationFiled: May 29, 2002Publication date: December 5, 2002Inventor: Kevin L. Shinler

Publication number: 20020179115Abstract: A cloth pouch attachment for a scrub brush including an expandable pouch portion dimensioned for receiving a head portion of a scrub brush therein. The pouch portion has an open upper end for receiving the head portion therein. The pouch portion is comprised of a soft cloth material. The bristles are inserted into the pouch portion and the pouch is cinched on the head portion of the scrub brush. The soft cloth material will protect the finish of an automobile from being scratched by the scrub brush when it is used to clean the scratchable surface of the automobile.Type: ApplicationFiled: June 1, 2001Publication date: December 5, 2002Inventor: Angelo Alex
