Abstract

A comprehensive study of different fundamental aspects of light emission from defects in Si semiconductor devices is presented. Based on an experimental analysis, using a new highly sensitive spectroscopic photon emission microscope (SPEM) for continuous wavelength analysis (2.5 eV-1.2 eV), a unique assignment of the spectrum of the emitted light and the corresponding failure mechanism is established. Three distinguishable basic spectral categories were identified. They were attributed to gate oxide breakdown, metal shorts, and electro-static discharge caused junction spiking. The focused ion beam technique was used to look at the damage sites for confirmation of the SPEM results.
