Title:
CHEMICAL MECHANICAL POLISHING SLURRY AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/114309
Kind Code:
A1
Abstract:
Disclosed in the present invention are a chemical mechanical polishing slurry and an application thereof, the polishing slurry comprising: (a) grinding particles, (b) aminosilane coupling agent, (c) azole compound, (d) complexing agent, (e) organic phosphoric acid, (f) oxidizing agent, and (g) water. The chemical mechanical polishing slurry of the present invention is used for polishing through-silicon vias (TSV) and IC blocking layers, and is capable of meeting the requirements with respect to polishing rates and selection ratio for various materials. The polishing slurry has a strong correcting ability for a surface of a silicon wafer device, can achieve rapid planarization, and prevent local and overall corrosion that occurs in the metal polishing process, thus improving work efficiency and reducing production cost.
