ABSTRACT:
A process for reducing intrinsic stress and/or hydrogen content of a SiO.sub.x film grown by ECR chemical vapor deposition, wherein a vapor phase etchant is introduced while growing the silicon dioxide film. The presence of the etchant during the plasma deposition process allows for selective removal of high energy silicon dioxide molecules in the growing film thus reducing intrinsic stress within the film. The use of halogen etchants further reduces the amount of hydrogen present as hydroxyl within the film.
