Patent ID: 8247909

Claim:
A method for packaging a semiconductor package device with a cavity structure, comprising: providing a first die having an active surface and a back surface and a plurality of pads disposed on said active surface; providing a carrier substrate having a top surface and a back surface; attaching said first die on said carrier substrate, said active surface of said first die being disposed upward and said back surface of said first die being attached on said top surface of said carrier substrate; providing a second die having a top surface and a back surface, and a cavity structure being disposed on said top surface of said second die; attaching said second die on said active surface, said top surface of said second die being downward and attached on said active surface of said first die so as to said cavity structure being an inverse U-type which being disposed between said active surface of said first die and said top surface of said second die; performing a wire bonding process to form a plurality of conductive wires to electrically connect said plurality of pads on said active surface of said first die with said top surface of said carrier substrate; performing a molding process to form a polymer material to encapsulate said first die, said second die, said plurality of conductive wires and said top surface of said carrier substrate to form a package body; and forming a plurality of connecting components on said back surface of said carrier surface and being electrically connected said back surface of said carrier surface.
