Abstract: Embodiments relate to a polishing pad, which comprises a window having a hardness similar to that of its polishing layer. Since the polishing pad comprises a window having a hardness and a polishing rate similar to those of its polishing layer, it can produce an effect of preventing scratches on a wafer during a CMP process. In addition, the polishing layer and the window of the polishing pad have a similar rate of change in hardness with respect to temperature, so that they can maintain a similar hardness despite a change in temperature during the CMP process.
