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.

The present invention is directed to a method of making a three-dimensional fixed abrasive article, and a three dimensional fixed abrasive made thereby. The method comprises providing an abrasive composition comprising a plurality of abrasive particles and a binder precursor. The binder precursor comprises a polymerizable material consisting essentially of an ethylenically unsaturated material having one or more terminal functional groups of the same type of reactive functionality, a photoinitiator, and a thermal initiator. The abrasive composition is then applied onto a backing. The method then comprises at least partially curing the binder precursor by activating the photoinitiator, and further curing the binder precursor by activating the thermal initiator to provide a three-dimensional fixed abrasive.

The present invention provides an abrasive article that has abrasive composite members secured firmly in recesses in a backing sheet in a precise pattern whereby there is desired lateral spacing between each abrasive composite member. The present invention also provides a method for preparing the abrasive article comprising the steps of providing an embossed backing sheet having a plurality of recesses in the front surface of the backing sheet. The recesses are filled with an abrasive slurry that includes a plurality of abrasive grains dispersed in a binder precursor. An expanding agent is also provided in the recesses, either separate from the slurry or dispersed in the slurry. The expanding agent, when activated, expands the abrasive slurry outward and above the front surface of the embossed backing sheet. After the binder precursor of the abrasive slurry is hardened, individual abrasive composite members extend above the front surface of the embossed backing sheet. An alternative embodiment provides recesses that extend completely through the embossed backing sheet, so that abrasive composite members protrude from the front surface and from the back surface of the embossed backing sheet.

An energy sensitive composition comprising a monomeric organometallic complex essentially free of nucleophilic groups and which, upon exposure to energy, bonds to basic reactive sites on a substrate via the metal center, leaving the polymerizable group of the complex unreacted and unrestricted; an energy sensitive composition at least one energy sensitive organometallic group is incorporated in or appended to the backbone of a polymer, such that the resulting coordinatively unsaturated organometallic group or groups bond to basic reactive sites on a substrate, thus forming permanent bonds, and further, the adherent compositions are useful in applications such as adhesion of polymers to substrates, protective coatings, printing plates, durable release coatings, primers, binders, and paints.
