标题 :Triazole- And/Or Triazolium-Based Polymers And Copolymers As Additives For Chemical Mechanical Planarization Slurries
发明人：LARBIG GREGOR; KIRSCH PEER; HENGST MATTHIAS; SHI XIAOBO; STENDER MATTHIAS
权利人:VERSUM MAT US LLC
摘要:Synthesis of triazole- and/or triazolium-based polymers is disclosed. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising triazole- and/or triazolium-based polymers; and water. The use of the synthesized triazole- and/or triazolium-based polymers in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题:Polycationic Polymer Or Copolymer Having Different Cation Types For Slurries In Chemical Mechanical Planarization
发明人：LARBIG GREGOR; SHI XIAOBO
权利人:MERCK PATENT GMBH; VERSUM MAT US LLC
摘要:Synthesis of polycationic polymer or copolymer is disclosed. The polycationic polymer or copolymer are formed by at least one first cationic monomer and at least one second cationic monomer wherein the first cationic monomer and the second cationic monomer have different cationic groups; such as imidazolium group and non-imidazolium group. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising polycationic polymer or copolymer; and water are also disclosed. The use of the synthesized polycationic polymer or copolymer in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.

标 题 :Modified water-soluble polysaccharides having different cation types for slurries in chemical mechanical planarization
发明人：DAVIDI INBAL; LARBIG GREGOR; SHI XIAOBO; MA SANA
权利人:VERSUM MAT US LLC
摘要:Synthesis of cationic-modified water-soluble polysaccharide is disclosed. The cation is pendent to the polysaccharide backbone. Chemical Mechanical Planarization (CMP) slurries comprise abrasives; activator; oxidizing agent; additive comprising cationic-modified water-soluble polysaccharide; and water. The use of the synthesized cationic-modified water-soluble polysaccharide in the CMP slurries reduces dishing and erosion in highly selective tungsten slurries.
