The adoption of SOI structure into 90 nm IC devices makes the characterization very challenging. TEM characterization becomes more critical, challenging and indispensable in the failure analysis of such devices. To illustrate the application of TEM in this area, several unique examples including both cross-sectional and planar analysis are given here
Passive voltage contrast (PVC) using electron beam (E-beam) is the popular technique of the failure analysis procedure of real integrated circuit (IC) products. When the sample is exposed on the different energy electron beam, the surface of sample is charged positively or negatively. The charging characteristic is dependent on the secondary electron yield, but that is just qualitative analysis of...
