Abstract: A packaged power device involves no soft solder and no wire bonds. The direct-bonded metal layers of two direct metal bonded ceramic substrate assemblies, such as Direct Bonded Aluminum (DBA) substrates, are provided with sintered silver pads. Silver nanoparticle paste is applied to pads on the frontside of a die and the paste is sintered to form silver pads. Silver formed by an evaporative process covers the backside of the die. The die is pressed between the two DBAs such that direct silver-to-silver bonds are formed between sintered silver pads on the frontside of the die and corresponding sintered silver pads of one of the DBAs, and such that a direct silver-to-silver bond is formed between the backside silver of the die and a sintered silver pad of the other DBA. After leadforming, leadtrimming and encapsulation, the finished device has exposed ceramic of both DBAs on outside package surfaces.

Abstract: The invention generally relates to a packaging method of an ultra-thin chip, more specifically, the invention relates to a method for packaging the ultra-thin chip with solder ball thermo-compression in wafer level packaging process. The method starts with disposing solder balls on metal pads arranged on the front surface of semiconductor chips that are formed at the front surface of a semiconductor wafer. The solder balls are soften by heating the wafer, a compression plate is applied with a pressure on the top ends of the solder balls thus forming a co-planar top surface at the top ends of the solder balls. A molding compound is deposited on the front surface of the wafer with the top ends of the solder balls exposed. The wafer is then ground from its back surface to reduce its thickness to achieve ultra-thin chip.

Abstract: A semiconductor chip packaging on a flexible substrate is disclosed. The chip and the flexible substrate are provided with corresponding raised and indented micron-scale contact pads with the indented contact pads partially filled with a liquid amalgam. After low temperature amalgam curing, the chip and the substrate form a flexible substrate IC packaging with high conductivity, controllable interface layer thickness, micron-scale contact density and low process temperature. Adhesion between the chip and the substrate can be further enhanced by coating other areas with non-conducting adhesive.
