Classification: CPC B  H | IPC B  H

Claim 7:
8. A method of fabricating a semiconductor device, comprising:
providing a polishing pad with a surface that has plural recess portions, wherein an average width of the recess portions at one area of the surface in a direction parallel to the surface is 20 μm or less, and an average density of the recess portions at one area of the surface is 1,300/mm2 or more;
after providing the polishing pad, dressing the surface of the polishing pad with a dresser;
after dressing the surface of the polishing pad, holding the dressed polishing pad on a polishing table, wherein the dressed polishing pad includes the surface having the plural recess portions;
after holding the dressed polishing pad, supplying a slurry to the surface of the dressed polishing pad; and
after supplying the slurry, polishing a substrate with the slurry in a gap between the dressed polishing pad that includes the surface having the plural recess portions and the substrate.
