Integrated circuits can emit light when activated. Light EMission MIcroscopy (EMMI) uses this physical phenomenon to precisely localize specific areas in the silicon chip. By comparing differences in the emissions, it is possible to localize die level defects.
In addition, we can localize signal propagation failures by performing temporal analysis of the emitted light (TRE, Time Resolved Emission, TRI, Time Resolved Imaging).
