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 9):
A chemical mechanical polishing (CMP) method, comprising:\n providing a substrate having a first material and a second material formed thereon, wherein the second material is over a side surface and an upper surface of the first material, and a degree of hydrophobicity or hydrophilicity of the first material is different from that of the second material; providing a polishing slurry on the substrate; performing a CMP operation to remove the second material over the upper surface of the first material to expose the upper surface of the first material and an upper surface of the second material, wherein the polishing slurry and the upper surface of the second material have a first contact angle, and the polishing slurry and the upper surface of the first material have a second contact angle; modifying the upper surface of the second material to make a contact angle difference between the first contact angle and the second contact angle equal to or less than 30 degrees; and continuing to perform the CMP operation on the first material and the second material with the polishing slurry.
