  • Publication number: 20190105752
    Abstract: A surface treatment process of a CMP (chemical mechanical polishing) polishing pad includes steps of rough-machining, fine-machining and finish-machining a substrate in sequence with an abrasive belt with a particle size of 120-mesh, an abrasive belt with a particle size of 240-mesh and an abrasive belt with a particle size of 400-mesh, respectively till a target thickness of the substrate is obtained. In each processing stage, the surface of the substrate is sanded through effectively adjusting the height of the corresponding abrasive belt so as to effectively control a surface roughness of the substrate. Moreover, through the surface treatment process provided by the present invention, the initial surface roughness is consistent with the surface roughness in the usage process of the substrate, so as to solve the problem that the initial grinding rate is unstable, thereby significantly improving the stability of the substrate in the CMP process.
