Abstract: A method for forming a semiconductor device structure is provided. The method includes forming a first metal layer over a substrate, forming a dielectric layer over the first metal layer. The method includes forming a trench in the dielectric layer, and performing a surface treatment process on a sidewall surface of the trench to form a hydrophobic layer. The hydrophobic layer is formed on a sidewall surface of the dielectric layer. The method further includes depositing a metal material in the trench and over the hydrophobic layer to form a via structure.

Abstract: A chemical-mechanical polishing (CMP) system includes a head, a polishing pad, and a magnetic system. The slurry used in the CMP process contains magnetizable abrasives. Application and control of a magnetic field, by the magnetic system, allows precise control over how the magnetizable abrasives in the slurry may be drawn toward the wafer or toward the polishing pad.

Abstract: A planarization method includes: providing a substrate, wherein the substrate includes a first region and a second region having different degrees of hydrophobicity or hydrophilicity, the second region covering an upper surface of the first region; polishing the substrate with a polishing slurry until the upper surface of the first region is exposed; and continuing polishing and performing a surface treatment by the polishing slurry to adjust the degree of hydrophobicity or hydrophilicity of at least one of the first region and the second region. The polishing slurry and the upper surface of the second region have a first contact angle, and the polishing slurry and the upper surface of the first region have a second contact angle. The surface treatment keeps a contact angle difference between the first contact angle and the second contact angle being equal to or less than 30 degrees during the polishing.

Abstract: Methods of manufacturing a chemical-mechanical polishing (CMP) slurry and methods of performing CMP process on a substrate comprising metal features are described herein. The CMP slurry may be manufactured using a balanced concentration ratio of chelator additives to inhibitor additives, the ratio being determined based on an electro potential (Ev) value of a metal material of the substrate. The CMP process may be performed on the substrate based on the balanced concentration ratio of chelator additives to inhibitor additives of the CMP slurry.

Abstract: A cleaning apparatus and a method of using the cleaning apparatus are provided. The method includes first moving a pencil pad into contact with a top surface of a wafer, wherein the pencil pad is connected to a pivot arm and second moving the pivot arm in a sweeping motion from a first zone to a second zone, the first zone being closer to a center of the top surface of the wafer than the second zone, wherein the sweeping motion is controlled by a controller, the pivot arm moves at a first speed in the first zone and the pivot arm moves at a second speed in the second zone, wherein the first speed is different from the second speed.

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.
