Electronic package with stacked modules with channels passing through metal layers of the modules

Abstract

One aspect of the present invention provides an electronic package, comprising at least a first module and a second module arranged on top of the first module, the modules together in the form of a module stack, wherein the first and second modules are adhesively connected together, each module includes a substrate layer having at least one metal layer, at least one die and a plastic(s) package molding compound layer molded over said die or dice, in each module the die or dice are bonded on said substrate layer via the metal layer, a plurality of channels formed generally vertically acting as vias to connect the metal layers and arranged adjacent to the die or dice in at least one of the modules, some or all the channels provided with an inner surface coated with a conductive material layer or filled with a conductive material for electrical connection whereby the dice are electrically connected together, and means serving as an intermediary for providing electrical, mechanical and thermal connectivity, communication externally and connected to the channels.
