Abstract

The invention provides an etchant composition for polishing a semiconductor wafer, a method for preparing the etchant composition, and a method for polishing a semiconductor wafer by using the composition are provided to suppress the generation of particle, to obtain satisfactory surface smoothness and to improve polishing velocity. An etchant composition is an aqueous solution having the buffer solution composition comprising a weak acid and a quaternary ammonium, wherein the weak acid has pKa of 8.0-12.5 at 25 deg. C and the aqueous solution shows a buffer action at a pH range of 9.5-12 when diluted to 100 times. Also the etchant composition is an aqueous solution having the buffer solution composition comprising a weak acid, a quaternary ammonium and potassium wherein the weak acid has pKa of 8.0-12.5 at 25 deg. C and the aqueous solution shows a buffer action at a pH range of 9.5-12 when diluted to 100 times.
