All-Silicon Optical Technology for Contactless Testing of Integrated Circuits
- 367 Downloads
The uniqueness of the “all-silicon optical testing methodology” lies in the fact that it is fully an optical technique utilizing visible light, and it is completely compatible with standard silicon IC processing. It uses optical signals transmitted to the circuit for “inputting” the stimulus data and also uses optical signals from the circuit for observation of the logic output. In addition, this approach is fully compatible with the simultaneous use of mechanical probes for power and other signals. The approach avoids many of the limitations of other contactless techniques.
