Abstract
- The influence of the body layout on the charged device model (CDM) failure site and the robustness of the input buffer is explored. The failure analysis results confirm that the gate oxide is damaged. The failure site can be moved from the region above the channel to the overlap region between the source and the gate once the body layout is cut from a ring into a small segment, providing direct evidence demonstrating that the CDM current flows through the gate oxide via the body and the source of the transistor, since both connect to the Vss bus line. Otherwise, changing the body layout of the input buffer transistor does not vary the failure location. [ABSTRACT FROM AUTHOR]
