Abstract
A semiconductor device assembly includes a semiconductor die, a substrate, and a spacer directly coupled to the substrate. The spacer includes a flexible main body and a support structure embedded in the flexible main body, wherein the support structure has a higher stiffness than the flexible main body. The spacer carries the semiconductor die. The flexible main body of the spacer mitigates the effects of thermomechanical stress, for example caused by a mismatch between the coefficient of thermal expansion of the semiconductor die and the substrate. The embedded support structure provides strength needed to support the semiconductor die during assembly.
