Abstract
The present invention relates to a method for manufacturing a chemical mechanical polishing conditioner, comprising: (A) providing a non-planar substrate; (B) providing a binding layer disposed on the surface of the non-planar substrate; (C) providing a plurality of abrasive particles embedded in a surface of the binding layer, and (D) heat curing the binding layer, such that the non-planar substrate is deformed into a planar substrate during curing the binding layer, and the abrasive particles are fixed to a surface of the planar substrate by the binding layer; wherein, after step (D), tips of the abrasive particles have a leveled height. Therefore, the present can effectively improve the problem of thermal deformation of the substrate of the chemical mechanical polishing conditioner during a heat curing process, and enhance surface flatness of the chemical mechanical polishing conditioner.
