Abrasive Article Having A Window System For Polishing Wafers, And Methods

View page
US Patent:
6604985, Aug 12, 2003
Filed:
Nov 7, 2002
Appl. No.:
10/289750
Inventors:
Michael J. Muilenburg - Minneapolis MN
Jerry J. Fizel - River Falls WI
Richard J. Webb - Inver Grove Heights MN
John J. Gagliardi - Hudson WI
Robert J. Streifel - Woodbury MN
Wesley J. Bruxvoort - Woodbury MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B24B 4900
US Classification:
451 6, 451 10, 451 11, 451 41
Abstract:
A process for planarizing, polishing, or providing other modification of a wafer surface or other workpiece. The process includes using an abrasive article having a textured abrasive coating affixed to a backing. The abrasive article includes a monitoring element, such as a window, to allow transmission of radiation therethrough. The radiation level is monitored throughout the planarization process to determine the approach of the desired endpoint. The window in the abrasive coating can be an area devoid of abrasive coating or having minimal or a thinned abrasive coating.

US Patent:
62645331, Jul 24, 2001
Filed:
May 28, 1999
Appl. No.:
9/322559
Inventors:
Charles R. Kummeth - Hudson WI
Michael J. Muilenburg - Minneapolis MN
Gary B. Forsberg - Eagan MN
Robert J. Streifel - Woodbury MN
Daniel B. Pendergrass - Mendota Heights MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B24B 4900
B24B 5100
US Classification:
451 8
Abstract:
An apparatus and method for abrasively processing an article involves the use of an abrasive product provided with a machine discernable pattern representative of information of varying types. The pattern is read while the abrasive product moves relative to the article, and is used to control the movement of the abrasive product relative to the article. The pattern may include one or more of a machine discernable electrical characteristic, optical characteristic, topographic characteristic or magnetic characteristic. Reading the pattern may involve one or more of electrically, optically, mechanically or magnetically reading the machine discernable pattern provided on the abrasive product. The pattern may include one or more of indicia, protrusions, depressions, holes, voids, color or pigment variations, bar codes, magnetic transitions or periodic markings. The pattern may include one or more of indexing information, servo information, alignment information or abrasive product identification information.
