... in advanced technology nodes, due to the size, and design complexity. Several of the traditional methods (nanoprobing, OBIRCH, etc.) are shown to be inadequate to find defects in SRAM cells, either due to resolution, or time required. In recent years, the Electron Beam Induced Resistance Change (EBIRCH...
