摘要: A polishing pad may include a base and a plurality of polishing protrusions on a surface of the base. Each polishing protrusion may include a sidewall defining an opening in a surface of the polishing protrusion opposite the base. In addition, portions of the sidewall opposite the base may define a contact surface.

摘要: Provided is a chemical mechanical polishing (CMP) apparatus. The CMP apparatus may include a polishing pad including a plurality of concave regions. These concave regions may be two-dimensionally arranged in the polishing pad in a first direction and a second direction that are not perpendicular to each other and not parallel to each other. The concave regions arranged in the first direction may have a first pitch, and the concave regions arranged in the second direction may have a second pitch equal to the first pitch.
