摘要:
Three-dimensional Integrated Circuit (3D IC) based on through silicon via (TSV) has brought a drastic change in the IC technology. Since TSVs connect different layers of 3D stacks, their proper functioning is an essential prerequisite for the system operation. So, testing of TSV is essential for 3D IC. In this paper a cost-effective Built-in Self-Test (BIST) mechanism is proposed for the post-bond test of TSVs in 3D ICs. The test method aims at identifying single and multiple defective TSVs using low test time with minimum hardware. The time cycle needed for testing is calculated and is compared with previous proposed methods. The simulation result shows that the proposed BIST circuit is beneficial over prior BIST technology in terms of test time cycle and hardware requirement.
