Title: Klaus Roeschlau: Innovator in ESD Protection Technology
Introduction
Klaus Roeschlau is a notable inventor based in Grafing, Germany. He has made significant contributions to the field of electronics, particularly in the area of electrostatic discharge (ESD) protection circuits. With a total of 5 patents to his name, Roeschlau's work has had a considerable impact on integrated circuit design.
Latest Patents
One of his latest inventions is the "Diode-based ESD concept for DEMOS protection." This invention relates to an ESD protection circuit designed for integrated circuits that include a drain-extended MOS device and an output pad requiring protection. The circuit features a first diode connected to the output pad and a bias voltage rail, along with a second diode linked to another bias voltage rail. Additionally, an ESD power clamp is integrated between the two bias voltage rails. This clamp is constructed as a vertical npn transistor, with its base and emitter connected together. The collector of the npn transistor is created using an n-well implantation and a DEMOS n-drain extension, which produces a snapback-based voltage limiting characteristic. The diodes are formed with a lightly p-doped substrate region over a buried n-type layer, along with a p-well implant and an n-well implant separated by intervening substrate. A third diode may also be connected between the two bias voltage rails.
