Chemical mechanical polishing is essential for achieving global and local planarization of wafers in the IC manufacturing process, in which Chemical mechanical polishing (CMP) slurries are the main processing chemicals used. Depending on the objects of polishing, Anji’s chemical mechanical polishing slurries include copper slurries, barrier slurries, dielectric (silica-based and ceria-based abrasive) slurries, tungsten slurries, slurries for various substrates, formulated wet chemicals, and polishing slurries for new materials and applications. Currently, Anji’s copper and barrier slurries can meet the needs of chip manufacturers in China and has penetrated overseas markets. Other related polishing slurries are supplied to numerous chip manufacturers in China and abroad, and their production scale will be adapted to the needs of clients.
Used for the removal and planarization of copper and copper barrier layers in the integrated circuit manufacturing processes. Products have been used in mass production of logic chips . Development and validation of products continue for future technology nodes.
Used for the removal and planarization of tungsten in the integrated circuit manufacturing processes. Products have been used in mass production of logic chips etc. Development and validation of products continue for technology nodes under 28nm.
Used for the removal and planarization of intermediate electrical materials such as silicon dioxide and silicon nitride in the integrated circuit manufacturing processes.
Based on ceria abrasives, such slurries feature high-speed silica removal, high selectivity and high planarization efficiency, which are used for shallow trench isolation in IC manufacturing processes and other polishing processes where high-speed silica removal is required. Also, a wide range of new products have been developed to meet customer requirements.
Used for the polishing of silicon substrates and other semiconductor substrate materials. This product line includes silicon rough polishing slurries, silicon finishing slurries, silicon carbide slurries, gallium nitride slurries, etc.
To meet customers’s process requirements, Anji has developed various new technologies and processes based on chemical mechanical polishing slurries and the existing product platform. Included are through-silicon-via (TSV) slurries and hybrid bonding polishing slurries for 3D integration processes and special polishing slurries for new materials, such as polymers and carbon. A number of products have been mass-produced and supplied.
