Effects of TSVs (through-silicon vias) on thermal performances of 3D IC integration system-in-package (SiP)
نویسندگان
چکیده
Thermal performances of 3D IC integration system-in-package (SiP) with TSV (through silicon via) interposer/chip are investigated based on heat-transfer and CFD (computational fluid dynamic) analyses. Emphases are placed on the determination of (1) the equivalent thermal conductivity of interposers/chips with various copper-filled, aluminum-filled, and polymer w/o filler filled TSV diameters, pitches, and aspect ratios, (2) the junction temperature and thermal resistance of 3D IC SiP with various TSV interposers, (3) the junction temperature and thermal resistance of 3D stacking of up to 8 TSV memory chips, and (4) the effect of thickness of the TSV chip on its hot spot temperature. Useful design charts and guidelines are provided for engineering practice convenient. 2012 Elsevier Ltd. All rights reserved.

3D stacked chips have become a promising integration technology for modern systems. The complexity reached in multi-processor systems has increased the communication delays between processing cores, and an effective way to diminish this impact on communication is the 3D integration technology and the use of through-silicon vias (TSVs) for inter-layer communication. However, 3D chips present imp...

After many years as a hypothetical possibility, 3D integrated circuits (3D IC) stacking has emerged as a potential key enabler for maintaining semiconductor performance trends. Implementing 3D, however, will almost certainly require development of through-silicon vias (TSVs), which in the past few years have been elevated by the semiconductor industry to the status of a crucial mainstream techn...

In order to embed more functionality and performance into the same design space, 3D IC integration technology is one of the routes towards further miniaturization of ICs and consequently, printed circuit boards. 3D TSV (through silicon via) stacking of wafers or dies requires die-to-die interconnections to conduct electricity and heat. Typically micro bump contacts with solder (e.g. AgSn) and C...
متن کاملA Study on the Impact of Nano-Scale TSVs on 3D IC Designs
One of the most effective ways to minimize the area and capacitance overhead caused by 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 1μm, and it is expected to reach sub-micron dimensions in a few years. This downscaling of TSVs requires research on the impact of nanoscale TSVs on the quality of 3D IC ...
