Title: Chester Leung: Innovator in ESD Protection and RF IC Integration
Introduction
Chester Leung is a notable inventor based in Northfield, GB. He has made significant contributions to the field of electronics, particularly in the areas of electrostatic discharge (ESD) protection systems and integrated circuit component integration. With a total of 2 patents, his work showcases innovative solutions for high-frequency applications.
Latest Patents
Chester's latest patents include an ESD protection system for high-frequency applications. This system provides electrostatic discharge protection for circuits that utilize multiple power supply rails, ensuring that Vdd busses remain completely isolated while Vss busses are connected by pairs of complementary polarity diodes. This design effectively keeps Vss busses isolated from each other. Additionally, the I/O diodes of high-frequency I/O pads are arranged in a square layout to optimize the current/capacitance ratio. Each pair of power rails is equipped with its own power shunt circuit, which is strategically placed near the I/O pad it protects. The shunts are designed to clamp at a very low voltage during an ESD event, primarily using PMOS transistors. The protection circuit is configured to ensure that the worst-case ESD event will flow at most between two I/O pads and one power shunt.
Another significant patent is the single damascene method for RF IC passive component integration in the copper interconnect process. This method involves several steps, including providing a wafer with an exposed top-most planar copper interconnect. The wafer is divided into areas for a spiral inductor, a MIM capacitor, and a precision resistor. Each component is formed within its designated area, showcasing Chester's innovative approach to integrated circuit design.
