    摘要: A pad conditioner is provided for conditioning a polishing pad in chemical mechanical planarization (CMP). The pad conditioner comprises a plastic abrasive portion having a first hardness and optionally a brush portion having a second hardness less than the first hardness. The plastic abrasive portion comprises a base plate and a plurality of plastic nodules formed on a surface of the base plate, each of the plastic nodules having a planar top surface, wherein the planar top surface is positioned to substantially contact a polishing pad. The brush portion may be positioned adjacent to the plastic abrasive portion, the brush portion having a plurality of brush elements positioned to substantially contact the pad.
