Abstract
A semiconductor device has a differential height substrate including a first section and a second section thinner than the first section. The first section may include contact fingers for electrically coupling the semiconductor device to a connector in a slot of a host device. The second section may include one or more semiconductor dies and other components. Mold compound may encapsulate the semiconductor dies and other components, leaving the contact fingers in the first section of the substrate exposed. A second layer of mold compound may also be applied to a second, uniformly planar surface of the differential height substrate opposite a surface including the one or more semiconductor dies.
