A composite, dual-hardness polishing pad for use in a linear chemical mechanical polishing apparatus and a method for forming the pad are described. In the composite, dual-hardness polishing pad, a pad body is first provided which has a leading edge and a trailing edge for mounting to a linear belt immediately adjacent to a second polishing pad. The pad body is fabricated of a material that has a first hardness, the leading edge contacts an object being polished on the composite polishing pad before the trailing edge when the linear belt turns in a linear polishing process. The composite polishing pad further includes a buffer pad that is adhesively joined to the leading edge of the pad body for contacting the object that is being polished, the buffer pad may be fabricated of a material that has a second hardness which is at least 20% smaller than the first hardness such that impact on the object being polished is minimized during a linear polishing process. The present invention is further directed to a method for adhesively joining a buffer pad to a pad body of a polishing pad.
