Publication number: 20100248597Abstract: The equipment for cleaning polishing cloth is capable of increasing pressure of washing water received by the polishing cloth, securely removing deposits from the polishing cloth and improving polishing efficiency. The equipment is used in a polishing apparatus, in which a work piece is pressed onto the polishing cloth adhered on a polishing plate and the work piece is relatively moved with respect to the polishing plate with supplying slurry to the polishing cloth so as to polish the work piece. The equipment comprises a nozzle unit having a nozzle capable of spraying high-pressure washing water toward the polishing cloth so as to clean the polishing cloth. The nozzle is a straight nozzle capable of linearly spraying the washing water and perpendicularly spraying the washing water with respect to the polishing cloth.Type: ApplicationFiled: March 26, 2010Publication date: September 30, 2010Inventor: Kentaro SAKATA

Publication number: 20100062696Abstract: A retractable water dispenser arm system for a grinder/polisher includes a flexible hose formed, in part in a loop and affixed at at least one location to a base of the grinder polisher. A spout is mounted to an end of the flexible hose. A biased tension arm engages the hose at the loop, and is moveable, along with movement of the hose, to maintain the hose in tension. The biased tension arm includes a roller over which the hose traverses. A mount on the base is configured to receive the spout and is further configured for traverse of the hose therethrough. The mount includes a mount roller operably mounted thereto for guiding the hose through the mount.Type: ApplicationFiled: July 13, 2009Publication date: March 11, 2010Applicant: ILLINOIS TOOL WORKS INC.Inventor: Michael F.

Patent number: 7674156Abstract: A cleaning device for chemical-mechanical equipment, which includes: an irrotatable center shaft irrotatably coupled with a spindle which is rotated, the irrotatable center shaft including a first channel and a second channel formed in an interior of the irrotatable center shaft, cleaning liquid flowing into the first channel and compressed gas flowing into the second channel; and a nozzle block coupled with the spindle so as to revolve about the irrotatable center shaft above a polishing pad, the nozzle block mixing cleaning liquid supplied through the first channel with compressed gas supplied through the second channel so as to generate twin-fluid, and pressure-injecting the mixed twin-fluid on the polishing pad. Accordingly, cleaning liquid is pressurized so as to be rapidly injected on a polishing pad so that slurry particles and alien substances on the polishing pad are completely removed. Furthermore, wafer scratch can be prevented and the life of the polishing pad can also be increased.Type: GrantFiled: October 8, 2007Date of Patent: March 9, 2010Assignee: K.C. Tech Co., LtdInventors: Jun Ho Son, Sung Bum Seo

Publication number: 20100035525Abstract: Polishing pads used in CMP machines are consumable components that are typically replaced after a specific number of wafers have been processed. The life of a polishing pad is optimized by controlling the rate of material removal from the polishing pad by the conditioning disk. The conditioning disk removes enough material so the polishing surface can properly process the wafers but does not remove any excess material. Preventing excess material removal extends the life of the polishing pad. During CMP processing, the controller receives data concerning the torque applied to the conditioning disk and the torque applied to the arm to sweep the conditioning disk across the polishing pad. Based upon the detected operating conditions, the system can predict the rate of material removal and adjust the forces applied to the conditioning disk so that the life of the polishing pad is optimized.Type: ApplicationFiled: August 7, 2008Publication date: February 11, 2010Inventors: SAMEER Deshpande, Shou-Sung Chang, Hung Chih Chen, Roy C. Nangoy, Stan D. Tsai

Patent number: 7641538Abstract: An abrasive article includes a plurality of abrasive particles securely affixed to a substrate with a corrosion resistant matrix material. The matrix material includes a sintered corrosion resistant powder and a brazing alloy. The brazing alloy includes an element which reacts with and forms a chemical bond with the abrasive particles, thereby securely holding the abrasive particles in place. A method of forming the abrasive article includes arranging the abrasive particles in the matrix material, and applying sufficient heat and pressure to the mixture of abrasive particles and matrix material to cause the corrosion resistant powder to sinter, the brazing alloy to flow around, react with, and form chemical bonds with the abrasive particles, and allow the brazing alloy to flow through the interstices of the sintered corrosion resistant powder and form an inter-metallic compound therewith.Type: GrantFiled: March 15, 2004Date of Patent: January 5, 2010Assignee: 3M Innovative Properties CompanyInventor: Brian D.

Publication number: 20090275274Abstract: The invention provides a polishing pad conditioner that enables stabilization of brazing metal melting point, minimization of abrasive grain detachment by uniformizing and stabilizing abrasive grain brazing condition, and enhancement of flatness by minimizing thermal deformation of the metal support. The polishing pad conditioner is fabricated by brazing multiple abrasive grains to the surface of a metal support with brazing metal, wherein the composition of the brazing metal expressed in mass % is such that 70%?Ni+Fe?90% (provided that 0?Fe/(Ni+Fe)?0.4), 1%?Cr?25%, 2%?Si+B?15% (provided that 0?B/(Si+B)?0.8), and 0.1%?P?8%.Type: ApplicationFiled: August 17, 2006Publication date: November 5, 2009Inventors: Hiroaki Sakamoto, Toshiya Kinoshita

Publication number: 20090264054Abstract: A pedestal pad (workpiece supporting table pad) is arranged on the top of a pedestal (workpiece supporting table) for temporarily placing and holding a pre-polished or post-polished wafer (workpiece). This pedestal pad is formed of resin, and at least a surface of the pedestal pad which comes into contact with the wafer is non-absorbable to a fluid. The tissue of the pedestal pad is dense and smooth, and does not have any cavity, such as fine holes, which holds the fluid.Type: ApplicationFiled: July 1, 2009Publication date: October 22, 2009Applicant: FUJITSU MICROELECTRONICS LIMITEDInventors: Tetsuya SHIRASU, Katsuhiko AOYAMA, Fumihiko AKABOSHI, Kunichirou GOTOH

Publication number: 20090247054Abstract: A method of planarizing a semiconductor structure comprises moving a conditioning element on a surface of a polishing member, rotating the semiconductor structure relative to the polishing member against the surface of the polishing member, and rinsing the surface of the polishing member and the semiconductor structure. While the conditioning element is moved over the surface of the polishing member and the semiconductor structure is rotated against the surface of the polishing member, slurry is directed onto the polishing member. The step of rinsing comprises contacting the conditioning element to the surface of the polishing member.Type: ApplicationFiled: March 31, 2009Publication date: October 1, 2009Applicants: TEXAS INSTRUMENTS DEUTSCHLAND GMBH, TEXAS INSTRUMENTS INCORPORATEDInventors: Eugene C.
