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 7):
The planarization method of  claim 1 , wherein the surface treatment comprises adding a corrosion inhibitor to the polishing slurry, the corrosion inhibitor is liable to bond to the surface of the first region than to the surface of the second region, and the corrosion inhibitor has a degree of hydrophobicity or hydrophilicity similar to a degree of hydrophobicity or hydrophilicity of a material of the second region.
