Abstract:
An etching method using a remote plasma source (RPS) and a method of fabricating a semiconductor device, the etching method including generating a plasma by supplying a process gas to at least one RPS and applying power to the at least one RPS; and etching a first material film including SiNx by supplying the plasma and at least one control gas selected from HBr, HCl, HI, NH 3 , SiH 4 , CHF 3 , and CH 2 F 2  to a process chamber.

Claim (Index 11):
The etching method as claimed in  claim 10 , wherein the at least one control gas is supplied through:\n the first RPS, the second RPS, a passage between the first RPS and the process chamber, a passage between the second RPS and the process chamber, a shower head above the process chamber, or an inlet directly connected to the process chamber.
