摘要： A polishing pad comprising at least a polishing layer and a cushion layer, wherein a groove is formed on a polishing surface of the polishing pad, at least one of angles formed by the polishing surface and a side surface of the groove which continues to the polishing surface is 105-150° inclusive, and the cushion layer has a strain constant of 7.3×10−6 to 4.4×10−4 μm/Pa inclusive. The use of the polishing pad can achieve a purpose of preventing the fluctuation in a polishing rate while keeping the polishing rate at a high level.
摘要翻译：一种抛光垫，至少包括抛光层和缓冲层，其中在所述抛光垫的抛光表面上形成有由研磨表面和所述槽的侧表面形成的至少一个角度，所述至少一个角度继续进行抛光表面为105-150°，缓冲层的应变常数为7.3×10 -6〜4.4×10 -4μm/ Pa。抛光垫的使用可以达到在保持抛光速率高的同时防止抛光速度波动的目的。
