Abstract:
A semiconductor device module comprising:a support base having top and bottom surfaces and having an opening therein which extends from said top surface to said bottom surface, a length and a width of said support base defining a first area;a planar, thermally conductive substrate disposed in said opening in said support base such that a bottom surface of said substrate is disposed to contact an external heatsink located beneath said bottom surface of said support base, a length and a width of said planar, thermally conductive substrate defining a second area such that said first area is at least approximately six times larger than said second area;at least one semiconductor device mounted on a top surface of said thermally conductive substrate;at least one circuit board arranged above and spaced from said top surface of said base and having an opening therein that is situated above said thermally conductive substrate;at least another device mounted on a top surface of said circuit board;said top surface of said circuit board having at least one bonding pad area arranged at a periphery of said opening in said circuit board and being electrically connected to said another device; andat least one bonding wire for connecting said one semiconductor device to said bonding pad.
