Abstract:
An electronic package includes a carrier, semiconductor chip, a lid, and a lid-ring. The carrier includes a top surface and a bottom surface configured to be electrically connected to a system board. The semiconductor chip is electrically connected to the top surface. The lid is attached to the top surface enclosing semiconductor chip and includes a perimeter recess. The lid-ring is juxtaposed within the perimeter recess. The lid-ring exerts a reverse bending moment upon the lid to limit warpage of the electronic package.
