Abstract:
A composition for etching may include phosphoric acid, an ammonium-based compound, at least one of hydrochloric acid or a polyphosphate-based compound, and a silicon-containing compound.

Claim (Index 14):
A method for manufacturing a semiconductor device, the method comprising:\n forming a stacked structure by alternately and repeatedly forming insulating layers and sacrificing layers on a substrate; forming a trench penetrating the stacked structure; and removing the sacrificing layers by performing an etching process using a composition for etching, wherein the composition for etching comprises:\n phosphoric acid; \n an ammonium-based compound; \n hydrochloric acid or a polyphosphate-based compound; and \n a silicon-containing compound represented by Formula 1: \n wherein in Formula 1:\n R 2  is any one selected from hydrogen, an alkyl group of 1 to 10 carbon atoms, an amino alkyl group of 1 to 10 carbon atoms, an amino alkoxy group of 1 to 10 carbon atoms, and an alkoxy amino group of 1 to 10 carbon atoms, \n each of R 3 , R 4  and R 5  is hydrogen, an alkyl group of 1 to 10 carbon atoms, an amino alkyl group of 1 to 10 carbon atoms, an amino alkoxy group of 1 to 10 carbon atoms, an alkoxy amino group of 1 to 10 carbon atoms, or an amino group of 1 to 10 carbon atoms unsubstituted or substituted with an alkyl group, \n at least one of R 3 , R 4  or R 5  is an alkoxy amino group of 1 to 10 carbon atoms or an alkyl substituted or unsubstituted amino group of 1 to 10 carbon atoms, and \n n is 2 or 3.
