  • Patent number: 9224614
    Abstract: A method and associated composition for CMP processing of noble metal-containing substrates (such as ruthenium-containing substrates) afford both high removal rates of the noble metal and are tunable with respect to rate of noble metal removal in relation to removal of other films. Low levels of an oxidizing agent containing one or more peroxy-functional group(s) can be used along with a novel ligand to effectively polish noble metal substrates.

  • Publication number: 20150247063
    Abstract: Methods for removing, reducing or treating the trace metal contaminants and the smaller fine sized cerium oxide particles from cerium oxide particles, cerium oxide slurry or chemical mechanical polishing (CMP) compositions for Shallow Trench Isolation (STI) process are applied. The treated chemical mechanical polishing (CMP) compositions, or the CMP polishing compositions prepared by using the treated cerium oxide particles or the treated cerium oxide slurry are used to polish substrate that contains at least a surface comprising silicon dioxide film for STI (Shallow trench isolation) processing and applications. The reduced nano-sized particle related defects have been observed due to the reduced trace metal ion contaminants and reduced very smaller fine cerium oxide particles in the Shallow Trench Isolation (STI) CMP polishing.

  • Publication number: 20150132956
    Abstract: Provided are novel chemical mechanical polishing (CMP) slurry compositions for polishing copper substrates and method of using the CMP compositions. The CMP slurry compositions deliver superior planarization with high and tunable removal rates and low defects when polishing bulk copper layers of the nanostructures of IC chips. The CMP slurry compositions also offer the high selectivity for polishing copper relative to the other materials (such as Ti, TiN, Ta, TaN, and Si), suitable for through-silicon via (TSV) CMP process which demands high copper film removal rates.

  • Publication number: 20140315386
    Abstract: Solid metal compound coated colloidal particles are made through a process by coating metal compounds onto colloidal particle surfaces. More specifically, metal compound precursors react with the base solution to form solid metal compounds. The solid metal compounds are deposited onto the colloidal particle surfaces through bonding. Excess ions are removed by ultrafiltration to obtain the stable metal compound coated colloidal particle solutions. Chemical mechanical polishing (CMP) polishing compositions using the metal compound coated colloidal particles prepared by the process as the solid state catalyst, or as both catalyst and abrasive, provide uniform removal profiles across the whole wafer.
