  The present invention relates to a method of preparing a cerium oxide powder for a CMP slurry and a method of preparing a CMP slurry using the same, and more particularly, to a method of preparing a cerium oxide powder for a CMP slurry and a method of preparing a CMP slurry using the same in which the specific surface area of the powder is increased by preparing a cerium precursor, and then decomposing and calcinating the prepared cerium precursor. The pore distribution is controlled to increase the chemical contact area between a polished film and a polishing material, thereby reducing polishing time while the physical strength of powder is decreased, which remarkably reduces scratches on a polished film.

  本发明涉及一种用于CMP浆料的氧化铈粉末的制备方法以及使用相同的CMP浆料的制备方法，更具体地，本发明涉及一种制备氧化铈粉末的CMP浆料的方法，其中通过制备铈前体，然后分解和煅烧制备的铈前体来增加粉末的比表面积。通过控制孔隙分布来增加抛光膜和抛光材料之间的化学接触面积，从而减少抛光时间，同时降低粉末的物理强度，从而显着减少抛光膜上的划痕。
