In this work, we know that the Roughness on a CMP pad can present the status of a CMP Pad. If we manage a roughness of CMP pad, we can get a good CMP performance at an initial Pad life time. As a result of this work, we can get new generation Pad, called a Pre-Conditioned Pad. Based on experimental results, it is revealed that it can reduce a back up time of a CMP tool after changing its consumables. Because, it can improve the removal rate & defectivity at an initial pad life time.
