An improved method of in-situ conditioning of a polishing pad for use with a stationary pad conditioner during chemical mechanical polishing is described. A polishing table having a polishing pad on its surface is rotated in a first direction during polishing of a semiconductor wafer. A polishing pad conditioner is adjustably attached to the rotating polishing table such that the conditioner is stationary in relation to the rotating polishing table. The conditioner has a roughened surface which is in contact with the polishing pad providing in-situ conditioning during polishing of a semiconductor wafer.
