• The effect of the calcination process for cerium carbonate, a precursor of ceria, on the degree of synthesis and colloidal properties of ceria particles in aqueous media, which greatly influence shallow trench isolation (STI) chemical mechanical planarization (CMP) performance, was investigated. A two-step calcination process, consisting of decarbonation and crystal growth, resulted in a higher degree of synthesis for the same crystal size, a narrower particle size distribution, and better dispersion of the ceria particles, than conventional one-step calcination. These properties enhanced certain aspects of STI CMP performance, leading to a higher oxide removal rate, a better selectivity between oxide and nitride, and fewer defects, including remaining particles.
