... approaches to allow for 3D stacking of transistors (the so called “More than Moore”). This complex 3D geometry, with an abundance of opaque layers and interconnects, presents a great challenge for failure analysis (FA). Three-dimensional (3D) magnetic field imaging (MFI) has proven to be a natural, useful...
