Through silicon vias (TSVs) play an important role in 3-D chip integration. Effective and efficient testing for correct operation of TSVs is essential for 3-D integrated circuit design. This paper addresses the post-bond test and diagnosis of crosstalk faults among TSVs considering different impact ranges, and proposes a TSV grouping method for rectangular and hexagonal TSV placements such that as many TSVs as possible are tested simultaneously. Based on the results of the TSV grouping, we implement a high-efficiency, low-area-overhead TSV test architecture that reuses the existing boundary scan or IEEE 1500 wrapper cells typically present for prebond testing. Experimental results show the short test and diagnosis time as well as the low area overhead of the proposed test architecture.

TSV-based 3D-IC design can reduce the connection length of stacked ICs and enhance I/O bandwidth of heterogeneous integrated circuits. However the testing of 3D ICs is more complicated than that of 2D ICs. This paper presents an efficient on-chip 3D-IC test framework that can embed the test procedure of TSVs into the memory BIST process. By using the same test patterns generated from the memory BIST mechanism, the faults in both memories and TSVs can be detected simultaneously without extra time to test TSVs. The area overhead for on-chip testing can also be reduced significantly. Experimental results show that the proposed test framework can gain a good performance in test time reduction with very low area overhead penalty for a memory-logic stacked IC.
