Abstract
With the advancement of technology, semiconductor devices become more complex to satisfy the need for more features while reducing the size. For a component with varying material parts such as the semiconductor package, it is prone to warpage because of the different material properties present in the materials, mainly the thermal expansion coefficient. Package warpage emerge from varying temperatures from assembly processes which affects the performance of the device. This paper evaluates the product warpage by considering material selection through varying the material properties of different components. A validated model was employed using the material properties and dimensions from a previous study that compared a two-dimensional finite element model results to actual experimental data. The results have shown to be not significantly different from the two-dimensional model and experimental results. The developed model was then used to assess various material properties and identify the factors that could greatly affect the deformation in the semiconductor package. © 2019 IEEE.
