Abstract:
A method of finishing of a semiconductor wafer surface being finished comprising the steps of:a) providing an abrasive finishing element having an abrasive finishing surface and wherein the abrasive finishing surface comprises: a continuous phase comprising a synthetic resin polymer â€œAâ€ ; unconnected, discrete synthetic resin particles comprising a synthetic resin polymer â€œBâ€  having-a plurality of abrasive particles dispersed therein, the discrete synthetic resin particles comprising the synthetic resin polymer â€œBâ€  being dispersed in the continuous phase of synthetic resin polymer â€œAâ€ ; and a compatibilizing polymer â€œCâ€  coupling the discrete synthetic resin polymer â€œBâ€  particles with the continuous phase of the synthetic resin polymer â€œAâ€ ; and the synthetic resin polymer â€œBâ€  has a different the flexural modulus than that of the synthetic resin polymer â€œAâ€ ; and wherein b) positioning the semiconductor wafer surface being finished proximate to the abrasive finishing surface; and c) applying an operative finishing motion between the semiconductor wafer surface being finished and the abrasive finishing surface wherein the discrete synthetic resin particles are in finishing contact with the semiconductor wafer surface being finished.
