The new standard allows die makers to design dies which, if compliant to this standard, constitute, once stacked in a 3D-IC by a stack integrator, a consistent stack-level test access architecture. The standardization effort of the 3D-DfT (design-for-test) was initiated by imec. 3D-ICs exploit the vertical dimension for furth...
