Abstract
A method for detecting dielectric breakdown in the signal of cathodoluminescence in SEM is compared with both capacitive and secondary-emission methods. In the investigated samples of glass dielectrics, breakdowns of two types are found: surface and emission. The prospects for using cathodoluminescence to detect and localize defects in insulators that lower the breakdown voltage are discussed.
