    Abstract: PROBLEM TO BE SOLVED: To provide a chemical mechanical polishing (CMP) pad conditioner for solving the problem that an uneven face is formed during CMP process and the uneven faces are piled up in the following steps. SOLUTION: A conditioner 40 includes non uniform conditioning faces having a plurality of conditioning elements 44. The nonuniform conditioning face includes a first section 46 having a first cutting amount/unit width, and a second section 50 having a second cutting amount/unit width different from the first cutting amount/unit width. The difference of the cutting amount is given according to a different projection width of each conditioning element and according to the difference in linear density between the two sections.
