Title: Liguo Sun: Innovator in Integrated Passive Devices
Introduction
Liguo Sun is a notable inventor based in Plano, TX (US). He has made significant contributions to the field of integrated passive devices, holding a total of 4 patents. His work focuses on enhancing the performance and reliability of electronic components.
Latest Patents
Liguo Sun's latest patents include innovative designs that address common challenges in the industry. One of his patents describes an integrated passive device (IPD) formed on a silicon substrate covered with an oxide layer. This design effectively renders unwanted accumulated charge at the silicon/oxide interface immobile by creating trapping centers in the silicon surface. These trapping centers are produced by a polysilicon layer interposed between the silicon substrate and the oxide layer. Another significant patent details a thin film Integrated Passive Device (IPD) design that achieves isolation between conductive runners. This is accomplished by shielding the top and bottom regions of a noisy runner with metal shield plates derived from metal interconnect layers. The invention can be implemented by merely modifying the mask pattern for the metal interconnect layers, requiring no added elements or steps to fabricate the IPDs. This innovation is particularly suitable for use in Multi-Chip Modules (MCMs) or other arrangements where digital circuits and RF circuits are in close proximity.
