Abstract:
A unitary finishing element having a plurality of discrete finishing members for finishing a semiconductor wafer surface comprising:discrete finishing members wherein: each discrete finishing member has a surface area of less than the surface area of the semiconductor wafer surface being finished; each discrete finishing member has a discrete finishing member finishing surface and a finishing member body; each finishing member body is comprised of a continuous region of higher flexural modulus organic synthetic resin; and a ratio of the shortest distance across in centimeters of the discrete finishing member body to the thickness in centimeters of each discrete finishing 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 finishing members fixedly attached to the unitary resilient body in such a manner that each discrete finishing member is separate from its nearest discrete finishing member; and the unitary resilient body of organic polymer has a lower flexural modulus than the higher flexural modulus organic synthetic resin in the finishing member body.
