Abstract:
A planarization method and a CMP method are provided. The planarization method includes providing a substrate with a first region and a second region having different degrees of hydrophobicity or hydrophilicity and performing a surface treatment to the first region to render the degrees of hydrophobicity or hydrophilicity in proximity to that of the second region. The CMP method includes providing a substrate with a first region and a second region; providing a polishing slurry on the substrate, wherein the polishing slurry and the surface of the first region have a first contact angle, and the polishing slurry and the surface of the first region have a second contact angle; modifying the surface of the first region to make a contact angle difference between the first contact angle and the second contact angle equal to or less than 30 degrees.

Claim (Index 17):
A chemical mechanical polishing (CMP) method, comprising:\n providing a substrate having a dielectric material and a metal material formed thereon, wherein the metal material is over a side surface and an upper surface of the dielectric material, and the dielectric material and the metal material have different degrees of hydrophobicity or hydrophilicity; providing a polishing slurry over the substrate; performing a CMP operation to remove the metal material over the upper surface of the dielectric material to expose the upper surface of the dielectric material and an upper surface of the metal material; performing a surface treatment to the metal material to render the degree of hydrophobicity or hydrophilicity of the metal material in proximity to that of the dielectric material, such that the polishing slurry is uniformly dispensed on the upper surface of the dielectric material and the upper surface of the metal material; and continuing to perform the CMP operation on the dielectric material and the metal material with the polishing slurry uniformly dispensed on the upper surface of the dielectric material and the upper surface of the metal material.
