Lujt. Ogbuji et Dr. Harding, A NOVEL METHOD FOR DETERMINING THE STRENGTH OF PECVD SILICON (OXY)NITRIDE FILMS, Thin solid films, 263(2), 1995, pp. 194-197
A technique is described for determining the strength of plasma-enhanc
ed chemical vapor-deposited (PECVD) thin films from the bursting size
of microscopic bubbles formed by escaping volatiles upon annealing. Th
e strength of a PECVD SiOxNy (silicon oxynitride) film is estimated us
ing this approach.
