Polishing pad containing embedded liquid microelements and method of manufacturing the same

A polishing pad which performs a polishing operation by moving in contact with a surface of an object being polished, the polishing pad comprising:

• a polishing layer consisting of a hydrophilic polymeric matrix, and liquid non-water soluble microelements and hollow polymeric microelements embedded in the polymeric matrix,
• wherein open pores defined by the embedded liquid microelements are uniformly distributed across an exterior surface of the polishing layer, and the liquid non-water soluble microelements and the hollow polymeric microelements are uniformly distributed across an interior surface of the polishing layer such that the open pores are not present therein, and
• wherein the liquid material of the polishing pad includes at least one material selected from the group consisting of aliphatic mineral oil, aromatic mineral oil, silicon oil without a hydroxyl group in a molecule, soybean oil, coconut oil, palm oil, cotton seed oil, camellia oil, and hardened oil.
