Paper Title - Electrical Characterization of 3d Stacked Tsv with Voids
Through-silicon via (TSV) is a key component for the vertical interconnection of a 3D IC which can provide a
significant performance improvement with greatly reduced physical length of channels among vertically integrated chips.
TSV technology is used both in three-dimensional stacked ICs (3D-SICs), as well as in so-called 2.5D-SICs and supports
high performance, small footprint and lower power consumption. With increasing demands for smaller, multi-functional
electronic devices, 3D integration with TSV has attracted substantial attention and has been already on the way to
commercialization. A TSV is a conducting copper nail, which provides an electrical connection though the substrate and is
expected to be used extensively to provide high-speed interconnects between the top and bottom of the active dies. Duo to
the TSV fabrication process, the void often exists in the TSV. As the void cannot easily being avoided, the electrical
reliability of TSV integrated circuit (IC) shall be studied deeply for evaluating the electrical performance of the IC products
and enhancing the TSVs reliability issues. This paper evaluates the electrical characteristics of TSV during the change of the
void location and amounts using High Frequency Structure Simulator (HFSS) method.
Keywords- 3D Stacked-ICs, Through Silicon Via (TSV), High Frequency Structure Simulator (HFSS).
