Abstract:
A unitary refining element having a plurality of discrete refining members for refining a semiconductor wafer comprising:discrete refining members wherein: each discrete refining member has a surface area of less than the surface area of the semiconductor wafer being finished; each discrete refining member has a discrete refining member refining surface and a refining member body; each refining member body is comprised of a continuous region of organic synthetic resin; and a ratio of the shortest distance across in centimeters of the discrete refining member body to the thickness in centimeters of each discrete refining member body is at least 10/1; a unitary resilient body comprised of an organic polymer wherein the unitary resilient body has a plurality of discrete refining members attached to the unitary resilient body in such a manner that each discrete refining member is separated in space from its nearest discrete refining member; and the organic polymer of the unitary resilient body has a different flexural modulus than the organic synthetic resin in the continuous region of the refining member body.
