WebDec 24, 2009 · Chemical mechanical polishing (CMP) of copper in ammonium hydroxide based slurry in the presence of hydrogen peroxide was investigated. The polishing trend was found to be similar to that exhibited by other slurries containing hydrogen peroxide and various complexing agents used for Cu CMP. When the hydrogen peroxide … WebMar 27, 2003 · However, the polish rate increased dramatically to about 103 nm/min when a MAS containing 3 wt % colloidal ceria and 1.5 wt % calcined alumina particles was used at pH 10, but providing a polish rate selectivity between oxide and nitride for this composition of only about 2.8. A much higher value is desirable for effective application to STI CMP.
