Abstract
An integrated heat spreader is disclosed in which grooves are formed in a recess of the heat spreader to enhance the stiffness and strength of the integrated heat spreader without increasing production costs or complexity. The integrated heat spreader may be fabricated by providing a metal strip having raised portions thereon to provide a recess therebetween, forming grooves on a bottom surface of the recess, where the grooves extend along a periphery of the bottom surface which is substantially free of the raised portions, and subsequently singulating an integrated heat spreader from the metal strip.
