Title: Innovations by Yan Yun Xue

Introduction

Yan Yun Xue is an accomplished inventor based in Los Gatos, CA. He holds a total of 3 patents that showcase his expertise in semiconductor technology. His innovative designs have contributed significantly to the field, particularly in the development of advanced semiconductor devices.

Latest Patents

One of his latest patents is for a combined packaged power semiconductor device. This device features a flipped top source low-side MOSFET that is electrically connected to the top surface of a die paddle. It includes a first metal interconnection plate that connects the bottom drain of a high-side MOSFET or the top source of a flipped high-side MOSFET to the bottom drain of the low-side MOSFET. Additionally, a second metal interconnection plate is stacked on top of the high-side MOSFET chip. This three-dimensional packaging reduces the overall size of semiconductor devices while maximizing the chip's size within a package of the same dimensions, thereby improving performance. The design also simplifies the shape of the exposed bottom surface of the die paddle, enhancing heat dissipation.

Another significant patent is for a dual-side exposed semiconductor package with an ultra-thin die and its manufacturing method. In this innovation, a die with a source electrode and a gate electrode on the top surface is flipped and attached to a die paddle of a lead frame. It is then encapsulated with a first molding compound, which is ground down to reduce thickness. A mask is applied to expose the back of the flipped die, allowing for a metal layer to be deposited. A metal clip is attached to the back of the flipped die, and a second molding compound is deposited, exposing the top surface of the metal clip and the bottom surface of the lead frame.
