Abstract

Systems and methods for measuring and predicting the strength of semiconductor devices and packaging are disclosed. In some embodiments, a semiconductor device assembly comprises a package substrate, a semiconductor die electrically coupled to the package substrate, and a molding covering at least a portion of the semiconductor die, where the molding includes a through-mold via (TMV) extending from an upper surface into the mold material to a depth. The semiconductor device assembly can include a strain gauge disposed in the molding at the depth of the TMV and be electrically coupled to the TMV. For example, the TMV can extend to the surface of the semiconductor die, to the package substrate, or other critical areas of the semiconductor device assembly, enabling strain to be measured at these depths. The semiconductor device assembly can be used in testing to predict the strength of the die and packaging in real-world scenarios, such as being dropped, bent, or crushed.
