POLYURETHANE COMPOSITION FOR CMP PADS AND METHOD OF MANUFACTURING SAME |
摘要 |
<p>Polyurethane composition based on a certain polyether and polyester prepolymer reaction mixture, wherein the composition is utilized in manufacturing chemical mechanical polishing/planarizing (CMP) pads. The CMP pads have low rebound and can dissipate irregular energy as well as stabilize polishing to yield improved uniformity and less dishing of the substrate.</p> |
