TTSV array can not only reduce the thermal concentration more efficiently, but also lower the probability of thermo-mechanical failure.

To obtain the temperature and thermal stress distribution of the improved TTSVs, the heat conduction and thermal stress equations should be solved numerically.
Both our N-FEM code and commercial FEM software ANSYS are run for the case of single-layer TTSVs with Fin mentioned below.
1 shows the schematic of single-layer TTSVs and extended three-layer TTSVs [18].
As the TTSVs with Fin structure get closer to the hotspot, the corresponding maximum temperature of single-layer TTSVs is obtained, as shown in Fig.
Here, three-layer TTSVs are modeled to study thermal coupling among heat sources in different layers of a 3-D stack.
Utilizing the temperature dependent properties of various materials listed in Table 1, nonlinear maximum temperature of three-layer TTSVs with overlapped hotspots and staggered hotspots are also provided in Fig.
9(a) and (b) demonstrate steady-state 3-D thermal stress distribution of single and three-layer TTSVs, respectively.
In our Fin structure model, Fin is connected to the liner of TTSVs. By replacing Si[O.sub.2] of liner with BCB, we get the maximum thermal stress for Si[O.sub.2] and BCB depending on the thickness of liner in Fig.
