摘要

利用两种不同的亚微米分辨率x射线衍射技术,对硅中间层中tsv诱导应力进行了广泛的研究。通过模拟来解释实验应变结果。在室温下,硅中的应力和应变很小,而在退火温度(400°C)下的测量和模拟支持铜在TSV的某些区域的塑性行为。

Effect of the temperature on the strain distribution induced in silicon interposer by TSVs: A comparison between micro-Laue and monochromatic nanodiffraction
TSV-induced stress is extensively studied in silicon interposer by using two different submicron resolution X-ray diffraction techniques. Simulations are performed to interpret the experimental strain results. Stress and strain in silicon are found to be small at room temperature, while measurements and simulations at annealing temperature (400 °C) support a plastic behavior of copper in some regions of the TSV.
