Abstract: Through silicon via (TSV) technology is a key technology used in 3D integrated packaging to achieve high-density and high-performance interconnection, the thermal-mechanical reliability of TSV has a direct impact on the performance and lifetime of 3D integrated packaging. The thermal-mechanical reliability of TSV 3D interconnection is investigated from the aspects of TSV fabrication process, structural layout, material reliability and evaluation method, and the research methods and current research status are summarized and elaborated. In addition, in response to the development trend of reducing the size of TSV to the nanoscale, the reliability challenges faced by nanoscale TSV in the application of advanced chip backside power supply and higher density chip integration are discussed.

Key words: packaging technology, through silicon via, 3D interconnection, thermal-mechanical reliability
