Neocera Magma C30/C20
SQUID/GMR Current imaging system / 超导电流显像仪
It is the best known method for imaging weak buried currents in a non-destructive way for 3DIC or TSV (Through-Silicon Via) process or package. This enables us to measure currents and find defects through packaging and other materials. Equipment for non-destructive, high sensitivity and high resolution current imaging for failure analysis The Magma tool series has unique capability for isolating failures in complex devices, advanced packages, and full assemblies without de-capsulation or de-processing. The equipment is available in two configurations, either as C20 with a superconducting quantum interference device (SQUID) sensor, or as C30 with both SQUID and giant magnetoresistance (GMR) sensors build into the measurement head. While the SQUID sensor provides extremely high current sensitivity, to below 500 nA, and a lateral resolution down to 3 um, the GMR sensor is less current sensitive but delivers excellent lateral resolution to below 300 nm.
