Patent ID: 11380624

Abstract:
A device package and a method of forming the device package are described. The device package includes a substrate having a ground plane and dies disposed on the substrate. The dies are electrically coupled to the substrate with solder balls or bumps surrounded by an underfill layer. The device package has a mold layer disposed over and around the dies, the underfill layer, and the substrate. The device package further includes an additively manufactured electromagnetic interference (EMI) shield layer disposed on an outer surface of the mold layer. The additively manufactured EMI shield layer is electrically coupled to the ground plane of the substrate. The outer surface of the mold layer may include a topmost surface and one or more sidewalls that are covered with the additively manufactured EMI shield layer. The additively manufactured EMI shield may include a first and second additively manufactured EMI shield layers and an additively manufactured EMI shield frame.
