Abstract:
A method for fabricating semiconductor device includes the steps of: providing a material layer having a contact pad therein; forming a dielectric layer on the material layer and the contact pad; forming a doped oxide layer on the dielectric layer; forming an oxide layer on the doped oxide layer; performing a first etching process to remove part of the oxide layer, part of the doped oxide layer, and part of the dielectric layer to form a first contact hole; performing a second etching process to remove part of the doped oxide layer to form a second contact hole; and forming a conductive layer in the second contact hole to form a contact plug.

Claim (Index 5):
The method of  claim 1 , wherein the second etching process uses a gas selected from the group consisting of ammonia (NH 3 ) and nitrogen trifluoride (NF 3 ).
