Patent ID: 6972479

Claim:
A package with stacked substrates, comprising: a first substrate, having a first surface; at least a first element, connected to the surface of the first substrate; at least a conductive column, such that one end of the conductive column is connected to the surface of the first substrate; a second substrate, having a front surface and a back surface such that the back surface of the second substrate is connected to the other end of the conductive column, wherein the second substrate and the first substrate are located at different levels; at least a second element, connected to the front surface or the back surface of the second substrate; a lead-frame, having at least a lead, at least a down-set portion and at least an up-set portion such that the down-set portion is connected to the first substrate and the up-set portion is connected to the second substrate; and a molding compound, encapsulating part of the first substrate, the first element, the conductive column, part of the second substrate, and the down-set portion and the up-set portion of the lead-frame.
