摘要： A semiconductor package is provided with an Aluminum alloy lead-frame without noble metal plated on the Aluminum base lead-frame. Aluminum alloy material with proper alloy composition and ratio for making an aluminum alloy lead-frame is provided. The aluminum alloy lead-frame is electroplated with a first metal electroplating layer, a second electroplating layer and a third electroplating layer in a sequence. The lead-frame electroplated with the first, second and third metal electroplating layers is then used in the fabrication process of a power semiconductor package including chip connecting, wire bonding, and plastic molding. After the molding process, the area of the lead-frame not covered by the molding compound is electroplated with a fourth metal electroplating layer that is not easy to be oxidized when exposing to air.

摘要： 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.

摘要： A package structure for DC-DC converter disclosed herein can reduce the number of encapsulated elements as a low-side MOSFET chip can be stacked above the high-side MOSFET chip of a first die pad, through die pads of different thicknesses or interposers with joint parts of different thicknesses; moreover, it further reduces the size of the entire semiconductor package as a number of bond wires are contained in the space between the controller and the low-side MOSFET chip. Moreover, electrical connection between the top source electrode pin and the bottom source electrode pin of the low-side MOSFET chip is realized with a metal joint plate, such that when the DC-DC converter is sealed with plastic, the metal joint plate can be exposed outside to improve the thermal performance and effectively reduce the thickness of the semiconductor package.
