Patent ID: 7932800

Claim:
An integrated three-dimensional module comprising: at passives layer comprising at least one of an LTCC capacitor and a planar LTCC high conductance inductor, said LTCC high conductance inductor having ferromagnetic or ferrimagnetic ceramic sheets sintered together, an elongated conductor extending within one or more of the ferromagnetic or ferrimagnetic ceramic sheets, the elongated conductor having a height substantially the same as a height of at least one of the ferromagnetic or ferrimagnetic ceramic sheets, a connection pad having a surface exposed at an external surface of said three-dimensional module, and an inductor connection extending from said connection pad through at least one of the ceramic sheets to said elongated conductor; a planar heat spreader layer arranged on said passives layer, said heat spreader layer being comprised of materials different from said passives layer, and an actives layer located adjacent to said heat spreader layer, said actives layer having electrical connections on at least one side thereof and recesses in which active devices may be partially disposed.
