Abstract:
A method of modifying a surface of a wafer suited for fabrication of a semiconductor device comprising the steps of:a) providing a wafer comprising at least a first material having a surface etched to form a pattern and at least a second material deployed over the surface of the first material;b) contacting the second material of the wafer to a plurality of three-dimensional abrasive composites fixed to an abrasive article, the three-dimensional abrasive composites comprising a plurality of abrasive particles fixed and dispersed in a binder; andc) relatively moving the wafer while the second material is in contact with the plurality of abrasive composites until an exposed surface of the wafer is planar and comprises at least one area of exposed first material and one area of exposed second material.
