He has made significant contributions to the field of semiconductor technology, particularly in electrostatic discharge (ESD) protection circuits. With a total of 11 patents to his name, Lu's work has had a substantial impact on the industry.

Latest Patents

One of his latest patents is an ESD tolerant I/O pad circuit that includes a surrounding well. This innovative device features a semiconductor body with a first conductivity type and a pad. The surrounding well, which has a second conductivity type, is designed in a ring to encircle an area for an electrostatic discharge circuit within the semiconductor body. This well is relatively deep and not only defines the area for the ESD circuit but also provides the first terminal of a diode formed with the semiconductor body. Within this area, a diode connected to the pad and a transistor linked to the voltage reference are arranged in series, forming a parasitic device in the semiconductor body.

Another significant patent is the electrostatic discharge protection circuit. This circuit comprises a substrate of a first conductivity type, an annular well region of a second conductivity type, two first regions of the first conductivity type, and at least one transistor of the second conductivity type. The annular well region is positioned in the substrate, while the first regions are located within the substrate and surrounded by the annular well region. The transistor is situated on the substrate between the first regions and includes a source, gate, and drain. The annular well region and the drain are connected to a first voltage source, while the source and one of the first regions are linked to a second voltage source. The other first region is connected to a substrate triggering circuit.
