Abstract
This document discloses techniques, apparatuses, and systems for a semiconductor device with a porous air vent. The semiconductor device includes a semiconductor die mounted to a substrate at one or more contact pads. Underfill material is disposed between the semiconductor die and the substrate. The substrate includes a porous portion composed of a porous material. The porous material is such that air, but not the underfill material, may pass from an area between the semiconductor die and the substrate to an area below the substrate. As a result, air may pass through the porous portion during the underfill process and the underfill material may be retained. Thus, voids and back contamination may be limited to assemble a reliable semiconductor device
