Abstract
A semiconductor device includes a substrate, a semiconductor chip, and an array of contact elements electrically coupling the substrate to the semiconductor chip. The semiconductor device includes an underfill material between the substrate and the semiconductor chip and between the contact elements. A patterned structure is arranged on the substrate and extends from under the semiconductor chip through a keep-out zone around an edge of the semiconductor chip. The patterned structure provides a reservoir for the underfill material.
