The location and size of defects in a silicon dioxide film can be detected through the use of an electroluminescent layer. Referring to the figure, a layer of silicon dioxide 10 is grown silicon substrate 12. On top of the silicon dioxide layer 10, a thin film 14 of a suitably doped phosphor, such as ZnS with Cu and Cl, is deposited, followed by a thin, optically transparent metallic layer 16 (i.e., silver, gold, etc.).
