Patent ID: 8754522

Claim:
A device, comprising: a first body comprising a first semiconductor chip and a first metal layer; a second body comprising a second semiconductor chip and a second metal layer, wherein the first body is attached to the second body along a first plane, the first plane perpendicular to the first semiconductor chip and the second semiconductor chip; and an electrically conductive bulge arranged in the first plane and electrically coupling the first metal layer to the second metal layer, the electrically conductive bulge directly contacting a first surface of the first metal layer, the first surface of the first metal layer parallel to the first plane, and the electrically conductive bulge directly contacting a first surface of the second metal layer, the first surface of the second metal layer parallel to the first plane, wherein the first semiconductor chip is embedded in a first electrically insulating material, the second semiconductor chip is embedded in a second electrically insulating material, and the first electrically insulating material is attached to the second electrically insulating material via a third electrically insulating material along the first plane.
