Deprocessing of integrated circuits (ICs) is often the final step for defect validation in failure analysis (FA) cases with limited fault-isolation information and is an essential process for reverse engineering for design verification and competitive analysis... A new concept, based on plasma FIB deprocessing of devices from the silicon substrate backside, is now introduced to enable a greater success rate on lower- metal interconnects and high-density transistor levels.

How Our Software Was Used

Dragonfly was used for image analysis, stitching, and visualization in a near-real-time environment.
