Abstract:
The present invention relates to a method for selectively etching a silicon oxide film by using a low-temperature process in a semiconductor manufacturing process and, more specifically, the method comprises the steps of: putting, into a reactor, a substrate having a silicon oxide film and a silicon nitride film formed thereon; setting process conditions including a process temperature having a range of 0° C. to 30° C. below zero; and supplying process gas into the reactor under the process conditions so as to selectively etch the silicon oxide film with respect to the silicon nitride film.

Claim (Index 8):
The method of  claim 6 , wherein the process pressure in the reactor is maintained in the range of 50 to 150 Torr and the process temperature is maintained in the range of 10\u00b0 C. below zero to 30\u00b0 C. below zero.
