Pre-bond testing is directed to detecting defects that are inherent in the manufacture of the TSV itself, such as impurities or voids, while post-bond testing is directed to detecting faults caused by thinning, alignment, and bonding.
In this direction, two main approaches have been explored: pre-bond probing and built-in self test (BIST) techniques. Pre-bond probing is challenging since TSVs ...
Aug 7, 2015 · This paper proposes a BIST technique based on a simple unbalanced circuit comparing the behavior of two TSVs. Electrical simulation results show ...
Missing: Pre- bond
This paper presents an innovative pre-bond test method for TSVs in a 3D IC. The logic is devised around the cascadable arrangement of Cellular Automata (CA), ...

A new BIST (Built-in Self-Test) architecture has been developed to detect defects in TSVs (Through Silicon Vias) during the pre-bond phase.
The detection of defective TSVs in the earliest process step is of major concern. Hence, testing TSVs is usually done at different stages of the fabrication ...
In this context, this work proposes a simple pre-bond GIST architecture to improve the detection of hard and weak defects. ... Prebond Testing of Weak Defects in ...
