Abstract :
This article discusses a design-for-test (DFT) architecture for detecting and repairing faulty interconnects in 3-D IC circuits utilizing through silicon via (TSV) and interposer technology. The yield of such circuits depends highly on the ability to have functioning interconnects which connect the various dies. The authors also propose a built-in-self-test (BIST) framework to enable at-speed testing of such interconnects.
