High oxide vs nitride selectivity, low and uniform oxide trench dishing in shallow trench isolation (sti) chemical mechanical planarization polishing (cmp) |
| abstract |
Present invention provides Chemical Mechanical Planarization Polishing(CMP) compositions for Shallow Trench Isolation(STI) applications. The CMP compositions contain ceria coated inorganic oxide particles as abrasives, such as ceria-coated silica particles or any other ceria-coated inorganic metal oxide particles as core particles; suitable chemical additives comprising at least one organic carboxylic acid group, at least one carboxylate salt group or at least one carboxylic ester group and two or more hydroxyl functional groups in the same molecule; and a water soluble solvent; and optionally biocide and pH adjuster; wherein the composition has a pH of 2 to 12, preferably 3 to 10, and more preferably 4 to 9. |
