The chemical mechanical polishing (CMP) is generally consisted of pad, slurry including abrasives and so on. However, there are some problems in a general CMP: defects, a high Cost of Consumable (CoC), an environmental problem. The slurry including abrasives especially gives rise to not only increase a CoC, but also prohibition from achieving an eco-process. This paper introduces an abrasive capsulation pad to achieve an eco-process decreasing abrasives used is CMP. The binder wth a water a water swelling and a water soluble characteristic is used for an auto-conditioning, and the $CeO_2$abrasive is selected for an abrasive capsulation pad. Comparing with a conventional CMP, an abrasive capsulation pad appears good characteristics in ILD CMP and is able to achieve an eco-process decreasing wasted slurry.
