Abstract

In one example, an electronic device comprises a substrate comprising a conductive structure and an inner side and an outer side, a first electronic component over the inner side of the substrate and coupled with the conductive structure, a lid over the substrate and the first electronic component and comprising a first hole in the lid, and a thermal interface material between the first electronic component and the lid. The thermal interface material is in the first hole. Other examples and related methods are also disclosed herein.
