Abstract :
In the title paper, Janet al. applied the Kane-Mindlin theory to solve the strain field of a unit through silicon via (TSV) model in response to thermal loading ΔT. We comment on this paper by clarifying why the thermal strain αΔT cannot affect the mobility of electrons. We also demonstrate that a 2 × 2 TSV array would suffice to predict the maximum stress.
