3-D integration has been touted as an approach to reducing the lengths of critical paths in field-programmable gate arrays (FPGAs). A 3-D chip stacks a number of 2-D FPGA bare dies, interconnected by through-silicon vias (TSVs) and micro bumps, to attain a high packing density. However, the technology also introduces new types of defects, such as TSV void and microbump misalignment. Testing the interconnection...
The three-dimensional (3D) integration technology using through silicon via (TSV) provides many benefits over the 2D integration technology. Although many different manufacturing technologies for 3D integrated circuits (ICs) have been presented, some challenges should be overcome before the volume production of 3D ICs. One of the challenges is the testing of 3D ICs. This paper proposes test integration...
