Patent ID: 7758404

Claim:
An apparatus for cleaning an edge of a substrate, comprising: a composite applicator, including, a support material, the support material defining a body for the composite applicator, and the body being compliant when applied to the edge of the substrate so as to compress when contacting the edge of the substrate so that the edge of the substrate is at least partially pressed into the support material; a plurality of abrasive particles distributed throughout and within the support material, the support material defining a contact surface that will expose one or more of the plurality of abrasive particles that are to be placed in frictional contact with the edge of the substrate, each of the plurality of abrasive particles having a hardness level that is less than a hardness level of the substrate, and a fluid distributor embedded in the support material to enable introduction and distribution of fluids to the support material from the inside so as to assist in cleaning the edge of the substrate.
