摘要:
Disclosed are semiconductor die packages constructed from modules of embedded semiconductor dice and electrical components. In one embodiment, a semiconductor die package comprises a first module and a second module attached to the first module. One or more semiconductor dice are embedded in the first module, and one or more electrical components, such as surface-mounted components, are embedded in the second module. The first module may be formed by a lamination process, and the second module may be formed by a lamination process or a molding process. Patterned metal layers and vias provide electrical interconnections to the package and among the die and components of the package. The second module may be attached to the first module by coupling interconnect lands of separately manufactured modules to one another, or may be directly attached by lamination or molding.

A two tier power module has, in one form thereof, a PC board having upper and lower traces with an opening in the insulating material that contains a power device which has upward extending solder bump connections. An upper leadframe is mounted on the solder bumps and the upper tracks of the PC board. Vias in the PC board connect selected upper and lower traces. A control device is mounted atop the leadframe and wire bonded to the leadframe, and the assembly is encapsulated leaving exposed the bottom surfaces of the lower traces of the PC board as external connections. In another form the PC board is replaced by a planar leadframe and the upper leadframe has stepped sections which make connections with the planar leadframe, the bottom surfaces of the planar leadframe forming external connections of the module.
