Patent ID: 7008302

Claim:
A chemical mechanical polishing equipment, comprising: a polishing pad, having a polishing surface; a holder, implemented above the polishing pad for holding a wafer facing the polishing surface; a slurry supplier, implemented above the polishing pad; a conditioner, implemented above the polishing pad, capable of moving along a conditioning path on the polishing surface, wherein the conditioner comprises: a supporting rod having a longitudinal axis; and a plurality of conditioning blocks facing the polishing surface, implemented on the supporting rod, wherein the conditioning blocks are non-rotatable along the supporting rod and are spaced by a clearance between adjacent conditioning blocks, wherein at least part of a conditioning surface of one block overlaps at least part of a conditioning surface of an adjacent block along the direction of the longitudinal axis, so that the entire polishing surface is conditioned when conditioner moves along the conditioning path on the polishing surface.
