Abstract:
1. An IC package device, comprising: first and second package substrates; a first IC chip having solder balls formed on an active region of the first IC chip for electrically coupling the first IC chip to the first package substrate; a second IC chip having solder balls formed on an active region of the second IC chip for electrically coupling the second IC chip to the second package substrate; a heat spreader configured to disperse heat from the first and second IC chips, the heat spreader having a first surface coupled to a side of the first IC chip opposite the active region, and the heat spreader having a second surface coupled to a side of the second IC chip opposite the active region; and a first set of stiffening members coupled between corresponding peripheries of the first package substrate and of the first surface of the heat spreader, and a second set of stiffening members coupled between corresponding peripheries of the second package substrate and of the second surface of the heat spreader, a perimeter edge of the heat spreader extending to outside surfaces of the first and second sets of stiffening members that face away from the IC chips such that the perimeter edge of the heat spreader is accessible from outside the first and second sets of stiffening members.
