Ultra Fine Fiber Polishing Pad |
摘要 |
A polishing pad includes a body having a polymer layer and a polishing layer. The polymer layer has opposite first and second faces. The polymer layer includes a plurality of first ultrafine fibers and a polymer bonding the first ultrafine fibers together. The polishing layer is formed on the first face of the polymer layer. The polishing layer includes a plurality of second ultrafine fibers and is free of the polymer. The first and second ultrafine fibers are identical to each other. The second ultrafine fibers have a concentration of ultrafine fibers by volume higher than 80% and higher than that of the first ultrafine fibers of the polymer layer.
