Patent ID: 8236608

Claim:
A method of forming a semiconductor die assembly, comprising: aligning an inter-connecting bonding pad and a through silicon via of a silicon wafer which includes a first die to a through hole passing through a panel substrate which includes a second die embedded therein, thereby bonding said panel substrate facing to the backside of said silicon wafer, wherein said through silicon via is formed to connect said inter-connecting bonding pad; curing an adhesion dielectric layer that is formed on said panel substrate; sputtering a seed metal layer from the back side of said panel substrate; coating a photo resist from the back side of said panel substrate and opening said through hole area; filling a metal material into said through hole area to couple to said inter-connecting bonding pad of said first die and said through silicon via, and to couple to final terminal pads of said panel substrate; and stripping said photo resist and etching said seed metal layer.
