Patent number: 10011741Abstract: 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.Type: GrantFiled: March 2, 2016Date of Patent: July 3, 2018Assignee: VERSUM MATERIALS US, LLCInventors: Xiaobo Shi, John Edward Quincy Hughes, Hongjun Zhou, Daniel Hernandez Castillo, II, Jae Ouk Choo, James Allen Schlueter, Jo-Ann Theresa Schwartz, Laura Ledenbach, Steven Charles Winchester, Saifi Usmani, John Anthony Marsella, Martin Kamau Ngigi Mungai
