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.

摘要： A combined packaged power semiconductor device includes flipped top source low-side MOSFET electrically connected to top surface of a die paddle, first metal interconnection plate connecting between bottom drain of a high-side MOSFET or top source of a flipped high-side MOSFET to bottom drain of the low-side MOSFET, and second metal interconnection plate stacked on top of the high-side MOSFET chip. The high-side, low-side MOSFET and the IC controller can be packaged three-dimensionally reducing the overall size of semiconductor devices and can maximize the chip's size within a package of the same size and improves the performance of the semiconductor devices. The top source of flipped low-side MOSFET is connected to the top surface of the die paddle and thus is grounded through the exposed bottom surface of die paddle, which simplifies the shape of exposed bottom surface of the die paddle and maximizes the area to facilitate heat dissipation.
