1. A method for assembling a heat spreader system, comprising:
providing a plurality of bottom microporous wicks recessed in a bottom substrate; bonding a center substrate to said bottom substrate; bonding a top substrate having a top chamber portion to said center substrate to establish a first vapor chamber with said plurality of bottom microporous wicks; etching a bottom substrate side port along one side of said bottom substrate; etching a top substrate side port along one side of said top substrate; providing a center substrate side port in said center substrate; and aligning said bottom substrate side port, top substrate side port and center substrate side port to one another prior to said bonding said center substrate and said bonding said top subtrate.
