Method for bringing up lower level metal nodes of multi-layered integrated circuits for signal acquisition
 A method for bringing up lower level metal nodes of multi-layered IC devices (200) includes a step of boring a passage (210) down through the obstructing or non-target metal layers (220) exposing these layers, through the Inter Layer Dielectric layers (230), stopping at the target metal layer (240), and a step of depositing Gallium implanted insulator (250, 260) forming a node structure (280) with a conductive core (250) and an insulative sheath (260). The conductive core (250) brings up the target metal node or layer (240) and the insulative sheath (260) isolates the exposed non-target metal nodes or layers (220) from the target metal node (240) and the conductive core (250).
