抄録

We have observed a stress relaxation of a silicon oxide film made by plasma oxidation with the following nitridation. The radical nitridation reduces the compressive surface stress of the film expansion about 40-80%. This relaxation is larger than that of electron irradiation on the oxide film, which can reduce a disorder-induced surface stress. AES measurement shows the concentration of nitrogen does not precipitate on the SiO2/Si interface but is uniform in the film and is only 3 atom.% in the film.
