Vertically packaged MOSFET and IC power devices as integrated module using 3D interconnected laminates

摘要

An electronic package for containing at least a top packaging module vertically stacked on a bottom packaging module. Each of the packaging modules includes a semiconductor chip packaged and connected by via connectors and connectors disposed on a laminated board fabricated with a standard printed-circuit board process wherein the top and bottom packaging module further configured as a surface mountable modules for conveniently stacking and mounting to prearranged electrical contacts without using a leadframe. At least one of the top and bottom packaging modules is a multi-chip module (MCM) containing at least two semiconductor chips. At least one of the top and bottom packaging modules includes a ball grid array (BGA) for surface mounting onto the prearranged electrical contacts. At least one of the top and bottom packaging modules includes a plurality of solder bumps on one of the semiconductor chips for surface mounting onto the prearranged electrical contacts. The laminated board of the bottom packaging modules further has a thermal expansion coefficient substantially the same as a printed circuit board (PCB) whereby a surface mount onto the PCB is less impacted by a temperature change
