  • Patent number: 11854827
    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.

  • Publication number: 20230321789
    Abstract: A method of operating a chemical mechanical planarization (CMP) tool includes attaching a polishing pad to a first surface of a platen of the CMP tool using a glue; removing the polishing pad from the platen, wherein after removing the polishing pad, residue portions of the glue remain on the first surface of the platen; identifying locations of the residue portions of the glue on the first surface of the platen using a fluorescent material; and removing the residue portions of the glue from the first surface of the platen.

  • Publication number: 20230078573
    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.

  • Patent number: 11373879
    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.

  • Publication number: 20210313190
    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.
