Abstract :
One of the most effective ways to deal with the area and capacitance overhead issues with through-silicon vias (TSVs) in 3D ICs is to reduce the size of TSVs themselves. Today, the diameter of the smallest TSV available is around 1 μm, and this is expected to reach sub-micron dimensions in a few years. This downscaling of TSVs requires research on the impact of nano-scale TSVs on the quality of 3D IC designs to provide academia and industry with the quantified effects. In this paper, we investigate, for the first time, the impact of nano-scale TSVs on the area, wirelength, delay, and power quality of today and future 3D IC designs. For our future process technology, we develop a 22nm standard cell and interconnect library. We also use four sets of TSV-related dimensions in our GDSII-level 3D IC layouts. Based on these resources, we present a thorough study on the impact of nano-scale TSVs on the design quality of today and future 3D ICs.
