Abstract:
A semiconductor module comprising:a module board having semiconductor devices stacked on its top and bottom opposing surfaces; an upper heat sink thermally connected to a top surface of the semiconductor devices stacked on the top surface of the module board and enclosing the top surface of the module board; a lower heat sink thermally connected to a top surface of the semiconductor devices stacked on the bottom surface of the module board and enclosing the bottom surface of the module board; and a linking means for fixing the upper and lower heat sinks to the module board when the module board is placed between the upper and lower heat sinks, wherein the module board and the heat sinks include an opening formed therethrough configured to receive the linking means in such a manner that a gap is formed therebetween to absorb variations of thermal contraction and expansion of the upper and lower heat sinks and the module board.
